Summary: If you attempt to show a UIAlertView on iOS 8.3, and already have the keyboard open (e.g., a UITextField is first responder), and the alertViewStyle = UIAlertViewStylePlainTextInput, then the app will crash with a NSInternalInconsistencyException Steps to Reproduce: 1. Create UITextField and becomeFirstResponder 2. Create UIAlertView 3. Set alertViewStyle = UIAlertViewStylePlainTextInput 4. Show alert view (on iOS 8.3) Expected Results: It displays Actual Results: It crashes: *** Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'The layout constraints still need update after sending -updateConstraints to <_UIKeyboardLayoutAlignmentView: 0x10030ed40; frame = (0 0; 0 0); userInteractionEnabled = NO; layer = <CALayer: 0x17402c3e0>>. _UIKeyboardLayoutAlignmentView or one of its superclasses may have overridden -updateConstraints without calling super. Or, something may have dirtied layout constraints in the middle of updating them. Both are programming errors. Version: iOS 8.3 (12F70) Notes: I'm aware that UIAlertView has been deprecated in iOS 8, but for backwards compatibility with iOS 7 it's still convenient to use it. UIAlertController does not have this bug, and I can also workaround it by resigning the first responder before showing the UIAlertView. Configuration: iPhone 6
