Hi there,

UIActionSheet and UIAlertView are deprecated from iOS 8 and above. If you want to use these type of views, you must use UIAlertController and set the style to either UIAlertControllerStyleAlertSheet or UIAlertControllerStyleAlert.

This is from the Apple Docs: https://developer.apple.com/library/prerelease/ios/documentation/UIKit/Reference/UIAlertController_class/

UIAlertController* alert = [UIAlertController alertControllerWithTitle:@"My Alert"
                               message:@"This is an alert."
                               preferredStyle:UIAlertControllerStyleAlert];

UIAlertAction* defaultAction = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
   handler:^(UIAlertAction * action) {
     // CODE WHEN BUTTON WAS PRESSED

}];

[alert addAction:defaultAction];
[self presentViewController:alert animated:YES completion:nil];

You must add UIAlertAction's (which are the buttons of those views). With UIAlertController, you dont need to use a delegate to determine which button was pressed, you put the code you want inside handler of those UIAlertAction, then add them to the UIAlertController.

Good luck!

Danny Y.

This is my updated code for the video. However I'm not sure if this is the correct way to implement the "Cancel" button. Ash Furrow 

- (void)promptForSource {
    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Image Source"
                                                                   message:@"This is an alert."
                                                            preferredStyle:UIAlertControllerStyleAlert];

    UIAlertAction *camera = [UIAlertAction actionWithTitle:@"Camera" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action) {
                                                       [self promptForCamera];
                                                   }];

    UIAlertAction *photoRoll = [UIAlertAction actionWithTitle:@"Photo Roll" style:UIAlertActionStyleDefault
                                                      handler:^(UIAlertAction * action) {
                                                          [self promptForPhotoRoll];
                                                      }];

    UIAlertAction *cancel = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleDefault
                                                   handler:^(UIAlertAction * action) {
                                                       [self.presentedViewController dismissViewControllerAnimated:NO completion:nil];
                                                   }];

    [alert addAction:camera];
    [alert addAction:photoRoll];
    [alert addAction:cancel];
    [self presentViewController:alert animated:YES completion:nil];
}

I was going to post this exact code but I'm 5 months late :P There is a different style for cancel: UIAlertActionStyleCancel, this creates a separate cancel bubble button with darker text. I then just had the handler be nil since it automatically dismisses the view.
