UIAlertView and UIActionSheet not displaying properly in iOS 8 - objective-c

Question

UIAlertView and UIActionSheet not displaying properly in iOS 8, its hiding the view controller, also In alert view title is not displaying. I am running the app from Xcode 5.1.1.

Answer 1

Did you added any category for ViewController in your application. like below shown
#implementation UIViewController (CustomeAction)
- (void)setTitle:(NSString *)title{
// YOU CODE///
}
#end
This may the issue. I have solved by removing this category - (void)setTitle:(NSString *)title.
Note: From iOS 8, UIAlertViewController is inherited from UIViewController. If you use category method, it will be effect on UIAlertView & UIActionSheet titles.
You can refer apple docs at UIAlertController Class Reference

Answer 2

It should be noted, that UIAlertView and UIActionSheet is deprecated in iOS 8. You can check out this question or the apple link. May be it will help you.

Answer 3

You can use following code using UIAlerController for XCode 6 and IOS 8
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Title"
message:#"Your Message"
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction* ok = [UIAlertAction
actionWithTitle:#"OK"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
UIAlertAction* cancel = [UIAlertAction
actionWithTitle:#"Cancel"
style:UIAlertActionStyleDefault
handler:^(UIAlertAction * action)
{
[alert dismissViewControllerAnimated:YES completion:nil];
}];
[alert addAction:ok];
[alert addAction:cancel];
[self presentViewController:alert animated:YES completion:nil];
For ActionSheet
UIAlertController * alert= [UIAlertController
alertControllerWithTitle:#"Title"
message:#"Your Message"
preferredStyle:UIAlertControllerStyleActionSheet];
