When long pressing delete button on system keyboard, UITextView's delegate method textView:shouldChangeTextInRange:replacementText: is only called once for the first charater
Code to reproduce
- (void)viewDidLoad {
[super viewDidLoad];
UITextView *textView = [[UITextView alloc] initWithFrame:self.view.bounds];
textView.delegate = self;
[self.view addSubview:textView];
}
- (BOOL)textView:(UITextView *)textView shouldChangeTextInRange:(NSRange)range replacementText:(NSString *)text
{
NSLog(@"%@, %@", NSStringFromSelector(_cmd), NSStringFromRange(range));
return YES;
}

Hi,
One of our user reports his iPhone(iOS 14.5.1, iPhone12,1) reboot several times while using our app. We are using AudioUnit and Metal APIs in his situation. On his iPhone, I found these panic logs. Will it be a bug of newly released iOS 14.5.1
panic log - https://developer.apple.com/forums/content/attachment/2af54c5a-ce23-4b94-8143-2c1c3e232b8c
We are using AudioUnit and AUGraph to provide recording feature for millions of users. For a long time, we have been receiving user feedbacks about recording failures. Most of user logs show that AudioOutputUnitStart returns 1852797029 (kAudioCodecIllegalOperationError).It seems that once this error happens, AudioOutputUnitStart will always return this error code unit rebooting device or sometimes rebooting won't do the trick. Does anyone experience this error code or know the possible cause of it
