iOS8.0之后的UIAlertController

UIAlertView is deprecated. Use UIAlertController with a preferredStyle of UIAlertControllerStyleAlert instead.

可以通过以下方法进行替换：

UIAlertController * alert=   [UIAlertController                                 alertControllerWithTitle:@"Title"                                 message:@"Message"                                 preferredStyle:UIAlertControllerStyleAlert];   UIAlertAction* yesButton = [UIAlertAction                        actionWithTitle:@"Yes, please"                        style:UIAlertActionStyleDefault                        handler:^(UIAlertAction * action)                        {                            //Handel your yes please button action here                        }];   UIAlertAction* noButton = [UIAlertAction                            actionWithTitle:@"No, thanks"                           style:UIAlertActionStyleDefault                           handler:^(UIAlertAction * action)                           {                               //Handel no, thanks button                           }];   [alert addAction:yesButton];   [alert addAction:noButton];   [self presentViewController:alert animated:YES completion:nil];
