I have a UIViewController. In this controller I programmatically create a UITextView and set its delegate as my controller. I do this because I dont want to start editing the textView when I tap it.
ViewDidLoad method
UITextView* textView = [[UITextView alloc] initWithFrame:CGRectMake(9, 10, 302, 200)];
[textView setDelegate:self];
[self.view addSubview:textView];
[textView release];
I implemented the textViewShouldBeginEditing method to return NO here to disable the keyboard from showing up.
textViewShouldBeginEditing method
- (BOOL)textViewShouldBeginEditing:(UITextView *)textView
{
NSLog(@"Shouldbegin");
return NO;
}
The problem that appears
When I tap the textView it works once, but if i tap it again it will crash the application without any log. The weird thing when I hold the textView and release it, it will work like I want it to work. A normal single tap on the other hand doesn’t work a second time.
Edit
Single tapping quickly after each other also seems to work, so it seems that it wont work after i wait x seconds.
After some testing I found out it seems to be an iOS 5.X > bug. When running my App in a 4.3 device/simulator it works like it should. The error log on a iOS 5.1 device says the following:

Look in my main post where i edited the logfile.
