iOS 8中的UIAlertView按鈕標題變白白

Question

我正在使用一個具有大量警報視圖的舊應用程序。此應用程序在iOS7中工作正常，但在iOS8中警報視圖按鈕文本顏色變白並且不可見。功能明智，它也在iOS8中工作。 請參閱屏幕截圖瞭解更多信息。

你試試這個代碼

- (void)viewDidLoad { 
     [super viewDidLoad]; 
     // Do any additional setup after loading the view from its nib. 

     UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Alrt" message:@"This is the Message" preferredStyle:UIAlertControllerStyleAlert]; 
     UIAlertAction *cancelAction = [UIAlertAction 
             actionWithTitle:NSLocalizedString(@"Cancel", @"Cancel action") 
             style:UIAlertActionStyleCancel 
             handler:^(UIAlertAction *action) 
             { 
              NSLog(@"Cancel action"); 
             }]; 

     UIAlertAction *okAction = [UIAlertAction 
            actionWithTitle:NSLocalizedString(@"OK", @"OK action") 
            style:UIAlertActionStyleDefault 
            handler:^(UIAlertAction *action) 
            { 
             NSLog(@"OK action"); 
            }]; 

     [alertController addAction:cancelAction]; 
     [alertController addAction:okAction]; 

     [self presentViewController:alertController animated:YES completion:nil]; 
    }
