Question

With the latest iOS 8.3 release, our app starts to have a weird behavior.

After finishing textfield editing, the user can click the close button which brings up an

Answer 1

I too, had a keyboard popping up (with the cursor in the last-used textView) after closing a UIAlertController and here is a very simple fix:

Immediately before building and presenting the UIAlertController,

Using [_activeTextView resignFirstResponder]; the keyboard will reappear. Using [self.view endEditing:YES]; the keyboard will NOT reappear.

I hope this helps you.

Answer 2

If your deployment target is iOS 8+, try UIAlertController.

Here's a quick fix for UIAlertView: delay the invocation of showing the alert view when your text field or text view resigns first responder.

[self performSelector:@selector(showAlertView) withObject:nil afterDelay:0.6];

Answer 3

Try using the below code. It works fine for iOS 8 and below version

if (IS_OS_8_OR_LATER) {
        UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:title message:msg preferredStyle:UIAlertControllerStyleAlert];

        UIAlertAction *cancelAction = [UIAlertAction
                                     actionWithTitle:@"OK"
                                     style:UIAlertActionStyleCancel
                                     handler:^(UIAlertAction *action)
                                     {

                                     }];
        [alertVC addAction:cancelAction];

        [[[[[UIApplication sharedApplication] windows] objectAtIndex:0] rootViewController] presentViewController:alertVC animated:YES completion:^{

        }];
    }
    else{
        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil, nil];
        [alert show];
    }

}

you need to change alert for ios 8.3

first put this in your view

#define IS_IOS8 [[UIDevice currentDevice].systemVersion floatValue] >= 8.0

then

if (IS_IOS8) {

        UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:@"Unsaved Changes" message:@"Your changes have not been saved. Discard changes?" preferredStyle:UIAlertControllerStyleAlert];

        UIAlertAction *saveAction = [UIAlertAction
                                    actionWithTitle:@"Save"
                                    style:UIAlertActionStyleCancel
                                    handler:^(UIAlertAction *action)
                                    {
                                        [self save];
                                    }];

        UIAlertAction *cancelAction = [UIAlertAction
                                   actionWithTitle:@"Cancel"
                                   style:UIAlertActionStyleCancel
                                   handler:^(UIAlertAction *action)
                                   {
                                       [alertVC dismissViewControllerAnimated:YES completion:nil];
                                   }];


        UIAlertAction *discardAction = [UIAlertAction
                                   actionWithTitle:@"Discard"
                                   style:UIAlertActionStyleCancel
                                   handler:^(UIAlertAction *action)
                                   {
                                       [alertVC dismissViewControllerAnimated:YES completion:nil];
                                   }];



        [alertVC addAction:saveAction];
        [alertVC addAction:cancelAction];
        [alertVC addAction:discardAction];
        [self.view.window.rootViewController presentViewController:alertVC animated:YES completion:nil];

this will help you as it helps me in same problem. above code is compatible with both ios 7 & 8

Answer 5

I've noticed some weird behavior with textField keyboards and alertViews as well... Maybe make a bool called disableKeyboard and use it like this:

- (BOOL)textFieldShouldBeginEditing:(UITextField *)textField {

    if (disableKeyBoard) {

        disableKeyboard = NO;
        return NO;

    } else {

        return YES;

    }

}

- (void)alertView:(UIAlertView *)alertView willDismissWithButtonIndex:(NSInteger)buttonIndex {

    disableKeyboard = YES;

}

This is just a workaround and doesn't address the core issue, whatever it is. For this method to work you need to set the alertView and textField delegate methods in your header.

If anyone struggles with this, I hope this will help:

if (NSClassFromString(@"UIAlertController")) {
    UIAlertController* alert = ...
}
else {
    UIAlertView* alert = ...
}
