回答1:

Actually, you can change the tint color of the view of the UIAlertController in iOS8.

UIAlertController *alertController = ....
[alertController.view setTintColor:[UIColor greenColor]];

回答2:

for Swift 3, use:

alertController.view.tintColor = UIColor.red

AFTER you present your alert controller

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

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

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

And on iOS 9 :

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

The best way (And easiest) is the following:

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.

Hope it helps

Can't customize the appearance of alert views.

For more info UIAlertView Class Reference:

The UIAlertView class is intended to be used as-is and does not support subclassing. The view hierarchy for this class is private and must not be modified.

You can't change alert views. If you really needed you can use custom ones.
