The Travis Weerts answer should work if you are using a UIAlertController. For those using UIAlertView, you can use the UIView appearance settings.

如果您使用的是UIAlertController,Travis Weerts的答案应该有效。对于使用UIAlertView的用户,可以使用UIView外观设置。

You can aim the alerts component this way on iOS < 9 :

您可以在iOS <9上以这种方式瞄准警报组件:

[[UIView appearanceWhenContainedIn:[UIAlertView class], nil] setTintColor:[UIColor redColor]];
[[UIView appearanceWhenContainedIn:[UIAlertController class], nil] setTintColor:[UIColor redColor]];

And on iOS 9 :

在iOS 9上:

[[UIView appearanceWhenContainedInInstancesOfClasses:@[[UIAlertView class]]] setTintColor:[UIColor redColor]];
[[UIView appearanceWhenContainedInInstancesOfClasses:@[[UIAlertController class]]] setTintColor:[UIColor redColor]];

The best way (And easiest) is the following:

最好的方法(也是最简单的)如下:

alert = UIAlertController(title: "foo", message: "foo", preferredStyle: UIAlertControllerStyle.Alert)
alert.addAction.... foo
...foo
alert.view.backgroundColor = UIColor.orangeColor()
alert.view.tintColor = UIColor.orangeColor()
alert.view.layer.cornerRadius = 0.5 * alert.view.bounds.size.width

It gives also a plus effect of a "round faded orange circle" in the background.

它还在背景中给出了“圆形褪色橙色圆圈”的加号效果。

Hope it helps
