更改UIActionSheet按钮背景颜色和按钮字体 [英] Change UIActionSheet buttons background color and button font

问题描述

我的应用程序中有一个UIActionSheet。我想更改操作表按钮的背景颜色和按钮的字体。我在下面的代码中找到了一个搜索：

I have a UIActionSheet in my application. I want to change the background color of actionsheet buttons and the font of the buttons. I made a search found below code:

for (UIView *_currentView in actionSheet.subviews)
        {
            if ([_currentView isKindOfClass:[UIButton class]])
            {
               //DO YOUR WORK
            }
        }

但此代码不适用于ios 8.对于ios我也在以下代码中找到：

but this code is not working on ios 8. for ios I found below code too:

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

但此代码仅更改按钮的字体颜色。

but this code only changes the button's font color.

有没有办法改变按钮的背景颜色？

Is there a way for changing the button's background color too?

推荐答案

基本上你要做的是什么你不应该做，也不应该做。 UIActionSheet和U​​IAlertController提供具有极少数变体和完全标准外观的标准视图。你不应该试图弄乱它。

Basically what you are trying to do is something you should not do and should never have been doing. UIActionSheet and UIAlertController provide standard views with a very small number of variants and a completely standard appearance. You should not attempt to mess with that.

然而，不要放弃希望！没有什么可以阻止你设计你想要的自己的视图。在iOS 8（和iOS 7）上，这非常简单，因为您可以制作一个呈现的视图控制器，其视图滑动到屏幕上并仅部分覆盖它，就像警报表一样。因此，请继续创建您自己的非标准按钮列，而不是尝试修改Apple的标准。

However, don't give up hope! Nothing stops you from devising your own view that looks however you want. And on iOS 8 (and iOS 7) this is very easy, because you are allowed to make a presented view controller whose view slides onto the screen and covers it only partially, just like an alert sheet. So go ahead and create your own non-standard column of buttons, rather than trying to modify Apple's standard.
