Hello everyone, I'm working on an iOS application using Objective-C and UITabBarController. My app has more than 5 tabs, so the additional tabs are placed under the "More" tab. However, I've encountered an issue specific to iOS 18 where the first item in the "More" tab does not show up properly. This issue does not occur in iOS 17 or earlier versions. Here's my setup method: (void)mainTabbarSetUp { NSMutableArray *tabItemArray = [NSMutableArray array]; UIViewController *viewController1, *viewController2, *viewController3, *viewController4, *viewController5, *viewController6, *viewController7; UINavigationController *navviewController1, *navviewController2, *navviewController3, *navviewController4, *navviewController5, *navviewController6, *navviewController7; viewController1 = [[UIViewController alloc] init]; navviewController1 = [[UINavigationController alloc] initWithRootViewController:viewController1]; navviewController1.tabBarItem.title = @"Watch List"; navviewController1.tabBarItem.image = [UIImage imageNamed:@"tab_icn_watchlist"]; [tabItemArray addObject:navviewController1]; // Similarly adding other view controllers... viewController6 = [[UIViewController alloc] init]; navviewController6 = [[UINavigationController alloc] initWithRootViewController:viewController6]; navviewController6.tabBarItem.title = @"Cancelled"; navviewController6.tabBarItem.image = [UIImage imageNamed:@"tab_icn_cancelled"]; [tabItemArray addObject:navviewController6]; self.mainTabBarController.viewControllers = tabItemArray; } What I've Tried: Verified that each view controller is correctly initialized and assigned to a UINavigationController before being added to the tab array. Logged the contents of the moreNavigationController to confirm that it contains the correct view controllers. Tested by reducing the number of view controllers to less than 5, and the issue does not occur. Ensured that all UINavigationControllers are configured consistently (e.g., translucency, bar style, etc.).

My view controller has this property: @property NSMutableArray *tableCities; Whenever I press a button a new city object is added to this array, it consists of a dictionary of NSStrings containing the name and state of the city being added. Now, I have an NSPopUpButton that I'd like to bind to the city name of all cities in this NSMutableArray, how exactly can I achieve this with the Bindings Inspector?

I understand the mvc thing kinda, theres an array as a model, a tableview as a control, and the interface as a control (right?) so like, I drag an array controller on to the form display thing, assign a delegate to it the view and app module/header, add data to it and the tableview updates after I add a function to it? in vs the events are in the event browser, do I just copy and paste the code from the tutorial? how do I add controls and do all the advanced stuff? the documentation on developer.apple.com isnt that detailed, and most books are outdated or n/a since its objective c tutorials would be nice, some home grown method would be cool too thank you unidef warrell yashizzo

For a Cocoa project I have this table view controller: @interface TableViewController : NSObject <NSTableViewDataSource, NSTableViewDelegate> @property (nonatomic, strong) NSMutableArray *numbers; @property (nonatomic, strong) NSMutableArray *letters; @end #import "TableViewController.h" @implementation TableViewController - (NSMutableArray *)numbers { if (!_numbers) { _numbers = [NSMutableArray arrayWithArray:@[@"1", @"2", @"3", @"4", @"5", @"6", @"7", @"8", @"9", @"10"]]; } return _numbers; } - (NSMutableArray *)letters { if (!_letters) { _letters = [NSMutableArray arrayWithArray: @[@"a", @"b", @"c", @"d", @"e", @"f", @"g", @"h", @"i", @"j"]]; } return _letters; } // NSTableViewDataSource Protocol Method - (NSInteger)numberOfRowsInTableView:(NSTableView *)tableView { return self.numbers.count; } // NSTableViewDelegate Protocol Method -(NSView *)tableView:(NSTableView *)tableView viewForTableColumn:(NSTableColumn *)tableColumn row:(NSInteger)row { NSString *identifier = tableColumn.identifier; NSTableCellView *cell = [tableView makeViewWithIdentifier:identifier owner:self]; if ([identifier isEqualToString:@"numbers"]) { cell.textField.stringValue = [self.numbers objectAtIndex:row]; } else { cell.textField.stringValue = [self.letters objectAtIndex:row]; } return cell; } In the storyboard I created a NSTableView and set up the connection, after running it I get what I expected: okay, cool, but I have a question: why is this working even though I haven't created a NSTableView as a property for my ViewController or for my TableViewController? Also, there's another problem, now I want to add a button to this window such that, every time I click it, a new item should be added to this table(for now it can be anything) So I created a button and a method for this and linked the action to the story board: -(IBAction) addNewNumber:(id)sender { [_numbers addObject:@"1234"]; [_letters addObject:@"testing"]; } Now, every time I click this button I can see that this method is indeed being called and that indeed IT IS adding a new member to these arrays, the thing is, the table is not being updated, what gives? Any advice on how I can fix this behavior?

I understand we can use MPSImageBatch as input to [MPSNNGraph encodeBatchToCommandBuffer: ...] method. That being said, all inputs to the MPSNNGraph need to be encapsulated in a MPSImage(s). Suppose I have an machine learning application that trains/infers on thousands of input data where each input has 4 feature channels. Metal Performance Shaders is chosen as the primary AI backbone for real-time use. Due to the nature of encodeBatchToCommandBuffer method, I will have to create a MTLTexture first as a 2D texture array. The texture has pixel width of 1, height of 1 and pixel format being RGBA32f. The general set up will be: #define NumInputDims 4 MPSImageBatch * infBatch = @[]; const uint32_t totalFeatureSets = N; // Each slice is 4 (RGBA) channels. const uint32_t totalSlices = (totalFeatureSets * NumInputDims + 3) / 4; MTLTextureDescriptor * descriptor = [MTLTextureDescriptor texture2DDescriptorWithPixelFormat: MTLPixelFormatRGBA32Float width: 1 height: 1 mipmapped: NO]; descriptor.textureType = MTLTextureType2DArray descriptor.arrayLength = totalSlices; id<MTLTexture> texture = [mDevice newTextureWithDescriptor: descriptor]; // bytes per row is `4 * sizeof(float)` since we're doing one pixel of RGBA32F. [texture replaceRegion: MTLRegionMake3D(0, 0, 0, 1, 1, totalSlices) mipmapLevel: 0 withBytes: inputFeatureBuffers[0].data() bytesPerRow: 4 * sizeof(float)]; MPSImage * infQueryImage = [[MPSImage alloc] initWithTexture: texture featureChannels: NumInputDims]; infBatch = [infBatch arrayByAddingObject: infQueryImage]; The training/inference will be: MPSNNGraph * mInferenceGraph = /*some MPSNNGraph setup*/; MPSImageBatch * returnImage = [mInferenceGraph encodeBatchToCommandBuffer: commandBuffer sourceImages: @[infBatch] sourceStates: nil intermediateImages: nil destinationStates: nil]; // Commit and wait... // Read the return image for the inferred result. As you can see, the setup is really ad hoc - a lot of 1x1 pixels just for this sole purpose. Is there any better way I can achieve the same result while still on Metal Performance Shaders? I guess a further question will be: can MPS handle general machine learning cases other than CNN? I can see the APIs are revolved around convolution network, both from online documentations and header files. Any response will be helpful, thank you.

I have a Cocoa application and I'm trying to set up an NSImageView without using story board (using storyboard works just fine tho). Also, I'm kinda new to Cocoa so any advice is appreciated. Anyway so here's the deal, I created a class to encapsulate this image: @interface MyView : NSView { @private NSImageView* imageView; } @end @implementation MyView -(id) initWithFrame:(NSRect)frameRect { self = [super initWithFrame:frameRect]; if(self) { NSRect rect = NSMakeRect(10, 10, 100, 200); imageView = [[NSImageView alloc] initWithFrame:rect]; NSImage* image = [NSImage imageNamed:@"bob.jpeg"]; [imageView setImageScaling:NSImageScaleNone]; [imageView setImage: image]; [self addSubview: imageView]; } return self; } -(id) init { return [self initWithFrame:NSMakeRect(10, 10, 100, 100)]; } - (void)drawRect:(NSRect)dirtyRect { [super drawRect:dirtyRect]; // Drawing code here. } @end Now, in the view controller file, in the viewDidLoad I tried to load add this as a subview to get it to display my image: - (void)viewDidLoad { [super viewDidLoad]; MyView *customView = [[MyView alloc] init]; [self.view addSubview:customView]; } This kinda works, except that it loads the image twice, I ended up with two images instead of just one like I intended, what gives? what am I doing wrong here?

We're trying to implement a backup/restore data feature in our business productivity iPad app using UIDocumentPickerViewController and AppleArchive, but discovered odd behavior of [UIDocumentPickerViewController initForOpeningContentTypes: asCopy:YES] when reading large archive files from a USB drive. We've duplicated this behavior with iPadOS 16.6.1 and 17.7 when building our app with Xcode 15.4 targeting minimum deployment of iPadOS 16. We haven't tested this with bleeding edge iPadOS 18. Here's our Objective-C code which presents the picker: NSArray* contentTypeArray = @[UTTypeAppleArchive]; UIDocumentPickerViewController* docPickerVC = [[UIDocumentPickerViewController alloc] initForOpeningContentTypes:contentTypeArray asCopy:YES]; docPickerVC.delegate = self; docPickerVC.allowsMultipleSelection = NO; docPickerVC.shouldShowFileExtensions = YES; docPickerVC.modalPresentationStyle = UIModalPresentationPopover; docPickerVC.popoverPresentationController.sourceView = self.view; [self presentViewController:docPickerVC animated:YES completion:nil]; The UIDocumentPickerViewController remains visible until the selected external archive file has been copied from the USB drive to the app's local tmp sandbox. This may take several seconds due to the slow access speed of the USB drive. During this time the UIDocumentPickerViewController does NOT disable its tableview rows displaying files found on the USB drive. Even the most patient user will tap the desired filename a second (or third or fourth) time since the user's initial tap appears to have been ignored by UIDocumentPickerViewController, which lacks sufficient UI feedback showing it's busy copying the selected file. When the user taps the file a second time, UIDocumentPickerViewController apparently begins to copy the archive file once again. The end result is a truncated copy of the selected file based on the time between taps. For instance, a 788 MB source archive may be copied as a 56 MB file. Here, the UIDocumentPickerDelegate receives a 56 MB file instead of the original 788 MB of data. Not surprisingly, AppleArchive fails to decrypt the local copy of the archive because it's missing data. Instead of failing gracefully, AppleArchive crashes in AAArchiveStreamClose() (see forums post 765102 for details). Does anyone know if there's a workaround for this strange behavior of UIDocumentPickerViewController?

I am trying to set my UITextView as the first responder with [self.textView becomeFirstResponder] when my view controller called viewDidAppear. But sometimes it will cause crash with the error: [__NSPlaceholderArray initWithObjects:count:]: attempt to insert nil object from objects[0] all I did is just: - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; [self.textView becomeFirstResponder]; } So if anyone can tell me what happened and how to do? when I call the [self.textView becomeFirstResponder], what will be insert into the responders list? self.textView itself? Thanks very much!

I have an object that is an NSRuleEditorDelegate for an NSRuleEditor whose nestingMode is NSRuleEditorNestingModeList. There are 8 different possible criteria. Each criterion is optional but at least 1 is required (ruleEditor.canRemoveAllRows = NO). Each criterion should only be added once. How can I limit adding a criterion for a row if it is already in the editor at a different row? Thanks!

I've implemented Push Provisioning, but am having trouble testing it. When I try to add a payment pass with my activationData, encryptedPassData, and ephemeralPublicKey, I see the "Add Card to Apple Pay" screen, but then when I click "Add Card", I get a "Could Not Add Card" message. When I inspect the error from didFinishAddingPaymentPass, it reads "The operation couldn’t be completed. (PKPassKitErrorDomain error 2.)". Is this error PKPassKitError.Code.unsupportedVersionError? What does this error means? Additional context: We use cordova-apple-wallet to generate certificates and add payment pass.

We have developed an iOS app in objective-C and added integrations for shortcuts app - more specific the "automation" part of the app. Basically, user opens shortcuts app, select automation and when scanning NFC tag, user can select an action and our app shows 3 different actions. User select action, opens the app and action is executed. That all done in Obj-C and was working very well with no complaints till users start to update to iOS18. Now, when user starts to add automation, only thing they can do is select "open app". Our app actions are not showing any more. Is there something new in iOS 18 we have to update our app. I know Obje-C is considered "old", but the cost of upgrading an existing app and time is not available at the moment. Here's a code snippet of our shortcutIntent: <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>com.apple.security.application-groups</key> <array> <string>group.lw.grp1</string> <string>group.lw.grp2</string> </array> </dict> </plist> Shortcut Info-plist <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>NSExtension</key> <dict> <key>NSExtensionAttributes</key> <dict> <key>IntentsRestrictedWhileLocked</key> <array/> <key>IntentsRestrictedWhileProtectedDataUnavailable</key> <array/> <key>IntentsSupported</key> <array> <string>LockIntent</string> <string>TrunkIntent</string> <string>UnlockIntent</string> </array> </dict> <key>NSExtensionPointIdentifier</key> <string>com.apple.intents-service</string> <key>NSExtensionPrincipalClass</key> <string>IntentHandler</string> </dict> </dict> </plist> IntentHandler -(id)init{ self = [super init]; self.started = false; self.handler = [[AppIntentHandler alloc] init]; self.handler.userInfo = [[NSMutableDictionary alloc] init]; return self; } - (id)handlerForIntent:(INIntent *)intent { // This is the default implementation. If you want different objects to handle different intents, // you can override this and return the handler you want for that particular intent. if(!self.started){ self.started = YES; if([intent isKindOfClass:[LockIntent class]]){ NSLog(@"*intent lock selected*"); self.handler.userInfo = [self assignUserInfo:@"lock"]; }else if([intent isKindOfClass:[UnlockIntent class]]){ NSLog(@"*intent unlock selected*"); self.handler.userInfo = [self assignUserInfo:@"unlock"]; }else if([intent isKindOfClass:[TrunkIntent class]]){ NSLog(@"*intent trunk selected*"); self.handler.userInfo = [self assignUserInfo:@"trunk"]; } }else{ self.started = NO; } return self.handler; } A custom class to handle each intent @implementation AppIntentHandler #pragma mark - response handlers - (void)handleLock:(nonnull LockIntent *)intent completion:(nonnull void (^)(LockIntentResponse * _Nonnull))completion { LockIntentResponse *response = [[LockIntentResponse alloc] initWithCode:LockIntentResponseCodeContinueInApp userActivity:[self lockUserActivity]]; completion(response); } - (void)handleUnlock:(nonnull UnlockIntent *)intent completion:(nonnull void (^)(UnlockIntentResponse * _Nonnull))completion { UnlockIntentResponse *response = [[UnlockIntentResponse alloc] initWithCode:UnlockIntentResponseCodeContinueInApp userActivity:[self unlockUserActivity]]; completion(response); } - (void)handleTrunk:(nonnull TrunkIntent *)intent completion:(nonnull void (^)(TrunkIntentResponse * _Nonnull))completion { TrunkIntentResponse *response = [[TrunkIntentResponse alloc] initWithCode:TrunkIntentResponseCodeContinueInApp userActivity:[self trunkUserActivity]]; completion(response); } What have changed and what needs to be done to make our app's actions show in shortcuts app again. Could anyone point me to the right direction, documentations, blog post or code snippet? Thanks in advance for taking the time to help!

In Xcode 16.0 and 16.1 beta 2, running on macOS 15.1 beta 4, Developer Documentation for Objective-C is (at least partially) missing in the Navigator. Many of the entries appear to be for Swift. In Xcode 16.1 beta (i.e. beta 1), the documentation is normal. I did not find any posts in this forum about this, which is surprising and makes me wonder if the issue is isolated to particular configurations. In any event, I would appreciate any information anyone may have about this.

My project use manual reference counting and crash with UIAlertController when touch to Action Button: UIAlertController alert = [[UIAlertController alertControllerWithTitle:@"fsđs" message:@"fsđs" preferredStyle:UIAlertControllerStyleAlert ]autorelease]; UIAlertAction actionOk = [UIAlertAction actionWithTitle:@"Ok" style:UIAlertActionStyleDefault handler:nil]; [alert addAction:actionOk]; [self.window.rootViewController presentViewController:alert animated:YES completion:^{ }];

Hello we have created a function that is expanding copy module to support html format. Everything inside that function works fine but on 17.4+ IOS version copying the html element strike-through tag is not working (other HTML elements are working fine) . Looking the logs seems like are getting stripped. Also list that have indents won't work on paste indent is missing. Here is the code: void copyToClipboard(NSString *htmlContent) { UIPasteboard *pasteboard = [UIPasteboard generalPasteboard]; [pasteboard setValue:htmlContent forPasteboardType:@"public.html"]; } Does anyone know fix for this or when this will be fixed or will it be fixed in next update?

I am working with a React Native application that needs CPU usage data for debugging in a Production Release. Currently the module I wrote works for development but when the application is built for release that specific module errors out. I need help with configuring my Xcode project to include this module when building for release

I have a simple cocoa project, it has the default files like AppDelegate.m, AppDelegate.h , ViewController.h and ViewController.m what I want is to set the Window title to the dimension of the current window and update it as the user resizes it. My Storyboard has an Application Scene, a Window Controller Scene and a test Scene which contains my view: how do I go about this? should my ViewController or AppController implement NSWindowDelegate ?

I have an application with storyboard and I'm trying to set a constraint for the minimum size of my window (the view), but now matter what I do the constraint window is always grayed out, how do I go about this?

After upgrading to Xcode16RC, in an old project based on ObjC, I directly used the following controller code in AppDelegate: - (void)viewDidLoad { [super viewDidLoad]; // Do any additional setup after loading the view. UIButton *b = [[UIButton alloc]initWithFrame:CGRectMake(100, 100, 44, 44)]; [b setTitle:@"title" forState:UIControlStateNormal]; [self.view addSubview:b]; [b addTarget:self action:@selector(onB:) forControlEvents:UIControlEventTouchUpInside]; } - (IBAction)onB:(id)sender{ PHPickerConfiguration *config = [[PHPickerConfiguration alloc]initWithPhotoLibrary:PHPhotoLibrary.sharedPhotoLibrary]; config.preferredAssetRepresentationMode = PHPickerConfigurationAssetRepresentationModeCurrent; config.selectionLimit = 1; config.filter = nil; PHPickerViewController *picker = [[PHPickerViewController alloc]initWithConfiguration:config]; picker.modalPresentationStyle = UIModalPresentationFullScreen; picker.delegate = self; [self presentViewController:picker animated:true completion:nil]; } - (void)picker:(PHPickerViewController *)picker didFinishPicking:(NSArray<PHPickerResult *> *)results{ } Environment: Simulator iPhone 15 Pro (iOS18) Before this version (iOS17.4), clicking the button to pop up the system photo picker interface was normal (the top boundary was within the SafeAreaGuide area), but now the top boundary of the interface aligns directly to the top of the window, and clicking the photo cell is unresponsive. If I create a new Target, using the same codes, the photo picker page does not have the above problem. Therefore, I suspect it may be due to the old project’s .proj file’s info.plist, buildSetting, or buildPhase lacking some default configuration key value required by the new version, (My project was built years ago may be from iOS13 or earlier ) but I cannot confirm the final cause. iOS18.0 has the additional messages: objc[79039]: Class UIAccessibilityLoaderWebShared is implemented in both /Library/Developer/CoreSimulator/Volumes/iOS_22A3351/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 18.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/AccessibilityBundles/WebCore.axbundle/WebCore (0x198028328) and /Library/Developer/CoreSimulator/Volumes/iOS_22A3351/Library/Developer/CoreSimulator/Profiles/Runtimes/iOS 18.0.simruntime/Contents/Resources/RuntimeRoot/System/Library/AccessibilityBundles/WebKit.axbundle/WebKit (0x1980fc398). One of the two will be used. Which one is undefined. AX Safe category class 'SLHighlightDisambiguationPillViewAccessibility' was not found! Has anyone encountered the same issue as me?
