是否可以在iOS8的新XCode中自定义UIAlertController的字体和外观？ [英] Is it possible to customize the font and appearance of a UIAlertController in the new XCode w/ iOS8?

问题描述

我想知道是否可以使用UIAlertController自定义应用提醒。我没有看到任何明确表示你能做到的事情。有没有人知道我可以添加自定义外观的方式，特别是这些警报上的字体？

I'm wondering if it's possible to customize in app alerts with the UIAlertController. I haven't seen anything that explicitly says that you can. Does anyone know of a way I can add a custom appearance, particularly with fonts on these alerts?

推荐答案

你可以用appearanceWhenContainedIn。要设置背景颜色，这里有一个例子：

You can do it with appearanceWhenContainedIn. To set up background color, here's an example:

[[UIView appearanceWhenContainedIn:UIAlertController.class, nil] setBackgroundColor:[UIColor yellowColor]];

或淡色：

[[UIView appearanceWhenContainedIn:UIAlertController.class, nil] setTintColor:[UIColor whiteColor]];
