iOS中的警报控制器按钮颜色

我有以下实现，它实际上是一个带有两个按钮的警报。它工作正常，功能正常

唯一的问题是，我必须给这两个按钮不同的颜色。现在，它只有一种颜色，那就是红色。但我希望其中一个是绿色的，另一个是红色的

UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Message" message:nil preferredStyle:UIAlertControllerStyleAlert];

[alert addAction:[UIAlertAction
                  actionWithTitle:@"Cancel"
                  style:UIAlertActionStyleDefault
                  handler:^(UIAlertAction * action)
                  {

                  }]];


[alert addAction:[UIAlertAction
                  actionWithTitle:@"Apply"
                  style:UIAlertActionStyleDefault
                  handler:^(UIAlertAction * action)
                  {
                  }]];

alert.view.tintColor = [UIColor redColor];

您可以这样做：

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


  UIAlertController *alertController = [UIAlertController alertControllerWithTitle:@"Message" message:nil preferredStyle:UIAlertControllerStyleAlert];

  UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:@"Default" style:UIAlertActionStyleDefault handler:nil];
  [defaultAction setValue:[UIColor redColor] forKey:@"_titleTextColor"];


  UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil];
  [cancelAction setValue:[UIColor greenColor] forKey:@"_titleTextColor"];

  [alertController addAction:defaultAction];
  [alertController addAction:cancelAction];

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

)；否则，如果使用UIAlertView而不是UIAlertController，则需要自定义警报视图

  [cancelAction setValue:[UIColor greenColor] forKey:@"_titleTextColor"];

  [alertController addAction:defaultAction];
  [alertController addAction:cancelAction];

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

没有支持您所需内容的公共API。您需要自定义警报视图。没有支持所需内容的公共API。您需要自定义警报视图。
