It has been 2 years since I updated one of my apps. I am trying to create a distribution provisioning profile. I am seeing that the generic wildcard profile is no longer an option. If I have 30 apps do I need to create 30 distribution profiles? Is wildcard truly not an option?

When I first wrote my simple program using in-app purchase (I did not rewrite this app from C to Swift) when the user selects a purchase from the view controller this calls a simple purchase routine. If there are purchases it will update the state of the view controller's buyButton to allow a purchase. It also updates the productTitle and productDescription.
This used to work, but with the newer Xcode I am not allowed to change the state of the button from within the thread: "Modifications to the layout engine must not be performed from a background thread after it has been accessed from the main thread."
How do I enable the button then? Is using dispatch_async the correct solution?
Below is the routine that is called from the paymentQueue:
(void) productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
NSArray *products = response.products;
NSLog(@"in productsRequest");
myProduct = products;
if (products.count != 0)
{
_product = products[0];
//THIS IS WHAT IS CAUSING THE ISSUE *******
buyButton.enabled = YES;
_productTitle.text = _product.localizedTitle;
_productDescription.text = _product.localizedDescription;
}
else{
_productTitle.text = @"Product not found";
}
products = response.invalidProductIdentifiers;
for (SKProduct *product in products)
{
NSLog(@"Product not found: %@", product);
}
}
Should I be doing something like this for the UI changes:
dispatch_async(dispatch_get_main_queue(), ^{
self->buyButton.enabled = YES;
self->_productTitle.text = self->_product.localizedTitle;
self->_productDescription.text = self->_product.localizedDescription;
});

Does Xcode or Swift allow VOIP programming? If so, would someone point me in the right direction how I can write an app to do this. Does it require access to a service provider to allow telecommunication?

I have a piece of code that works on the iPhone. I load a UIImageView, make it invisible with an alpah = 0, and then play a video over it using AVPlayerLayer. When the video is done I remove the playerLayer (in a Notification) and change my alpha of myImage to 1.Two different things happen when I use an iPad.First, the alpha property does not do anything. The UIImage is visible.Second, setting the playerLayer frame to the size of the myImage from only works when I use[playerLayer setFrame:CGRectMake(0, 0, width, height)];instead of just usingplayerLayer.frame = myImage.frameHere is the code. Thanks for anyone that can clear this up for me.-(void)playMovie2: (NSString *) fileName{ #define degreesToRadian(x) (M_PI*(x)/180.0) CGFloat height, width; NSLog(@"in playMovie2 simulation!"); NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource: fileName ofType:@"mov"]]; AVPlayer *player = [AVPlayer playerWithURL:url]; playerLayer = [AVPlayerLayer playerLayerWithPlayer:player]; //cgrectmake: xfloat, yfloat, width, height if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){ height = self.view.frame.size.height; width = self.view.frame.size.width; [myImage setFrame:CGRectMake(0, 0, width, height)]; NSLog(@"iPhone %f %f",width, height); } else{ //we need this because I only used one XIB file for the iPhone and iPad //we need to get the dimension from the device height = [UIScreen mainScreen].currentMode.size.height; width = [UIScreen mainScreen].currentMode.size.width; height = (height/2); width = (width/2); [myImage setFrame:CGRectMake(0, 0, width, height)]; NSLog(@"iPad %f %f",width, height); } self.myImage.alpha = 0; //[playerLayer setFrame:CGRectMake(0, 0, width, height)]; // For some reason I need to use this playerLayer.frame = myImage.frame; //instead of this for iPad [self.view.layer addSublayer:playerLayer]; [player play];}
When I load a jpeg image into an imageview is the default action to just rescale the width and height of the image to fill the UIImageView? If I want to maintain the aspect ratio of the original image file is using something likeimageview.contentmode = UIViewContentModeAspectFit the step to take?

In objective C, how would I pass a playerLayer to an NSNotification observer? Do I need to use NSDictionary?
I'm refitting old moviePlayer code to the AVPlayer. I had a part when a user selected a movie from a list of choices the movie player would appear showing the clip along with a "done" button that would take the person back to the tableview.I've gotten the movie to play but I am having trouble figuring out how to have a "back/done" buttont to dismiss the Player. Here is what I have so far:-(void)playMovie: (NSString *) fileName{ NSLog(@"in playMovie second"); NSURL *url = [NSURL fileURLWithPath:[[NSBundle mainBundle] pathForResource: fileName ofType:@"mp4"]]; AVPlayer *player = [AVPlayer playerWithURL:url]; AVPlayerViewController *avMovie = [[AVPlayerViewController alloc]init]; //AVPlayerLayer *playerLayer = [AVPlayerLayer playerLayerWithPlayer:player]; avMovie.view.frame = self.view.bounds; avMovie.player = player; //playerLayer.frame = self.view.bounds; //[playerLayer setVideoGravity:AVLayerVideoGravityResizeAspect]; //[self.view.layer addSublayer:playerLayer]; [player play]; //show view controller [self addChildViewController:avMovie]; [self.view addSubview:avMovie.view]; }

I read data from a file and append it to a textView. I can then bring up the keyboard to edit the data. I save the data when exiting. If I used [self.myTextView resignFirstResponder] to remove the keybard and then come back to the textView I can no longer access the textView field. If I comment out the [self.myTextView resignFirstResponder] the keyboard never goes away, but the data is properly written to the textView field.Any ideas why the resignFirstResponder is causing an issue?
