Keyboard pops up after UIAlertView is dismissed on iOS 8.3 for iPad

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];

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

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

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
