NSInteralInconsistencyException - UIKeyboardLayoutAlignmentView

Question

I am getting the follow crash in my reports but I don\'t have a clue as to where to start looking! - any help appreciated. I have no calls or reference to UIKeyboardLayoutA

Answer 1

Ok, problem found an fixed. On iOS8.3 if you the keyboard is being displayed and then you try to display a UIAlertView or UIAlertController that has an input field you will get this crash.

Simple solution (for me) was to insert

[self.window endEditing:YES]; 

or

[self.view endEditing:YES];

in front of any alerts that do this and it no longer crashes

Update

In some cases I have also needed the following line (as outlined by Oren below), with the endEditing AND this line I have zero issues - but with one OR the other I have seen the odd crash which is weird - but the combo attack seems to work !

UITextField *txtEmail = [alertView textFieldAtIndex:0];
[txtEmail becomeFirstResponder];

This might help someone with the same issue. I came here to check out your answer, but it didn't work for me.

iOS 8.3 UIAlertController crashes when trying to add a textfield

To reiterate what's on the other thread, I solved it by setting the animated flag to "NO" when presenting the UIAlertController

[self presentViewController:alert animated:NO completion:nil];

Answer 3

I had the same issue using the Cordova Dialogs plugin in an Ionic app. It seems as of iOS 8.3 whenever a notification or alert is called and the keyboard is already visible, it tries to open another keyboard which causes the crash. I added this one line to the CDVNotification.m file in the plugin.

 if ([dialogType isEqualToString:DIALOG_TYPE_PROMPT]) {
    alertView.alertViewStyle = UIAlertViewStylePlainTextInput;
    UITextField* textField = [alertView textFieldAtIndex:0];
    **[textField becomeFirstResponder];** //added this line to Fix :)
    textField.text = defaultText;
}

This is definitely a bug with iOS8.3 when showing a UIAlertView or UIAlertController when the keyboard is already shown.

A workaround is to assign the alert view's textfield as the first responder. This works better than hiding the keyboard via resignFirstResponder or endEditing because the keyboard won't flicker.

UIAlertView *alertView = [[UIAlertView alloc] initWithTitle.......
alertView.alertViewStyle = UIAlertViewStylePlainTextInput;

UITextField *txtEmail = [alertView textFieldAtIndex:0];
[txtEmail becomeFirstResponder];

[alertView show];
