I created a custom class MyButtonextended from UIButton. Then added this inside the Identity Inspector:
我创建了一个自定义类myButton的距离延长UIButton。然后在里面添加了这个Identity Inspector：
After this, change the button type to Custom:
在此之后，将按钮类型更改为Custom：
Then you can set attributes like textColorand UIFontfor your UIButtonfor the different states:
然后，您可以为不同的状态设置类似textColor和UIFont适合您的属性UIButton：
Then I also created two methods inside MyButtonclass which I have to call inside my code when I want a UIButtonto be displayed as highlighted:
然后我还在MyButton类中创建了两个方法，当我希望 aUIButton显示为突出显示时，我必须在我的代码中调用它们：
- (void)changeColorAsUnselection{
[self setTitleColor:[UIColor colorFromHexString:acColorGreyDark]
forState:UIControlStateNormal &
UIControlStateSelected &
UIControlStateHighlighted];
}
- (void)changeColorAsSelection{
[self setTitleColor:[UIColor colorFromHexString:acColorYellow]
forState:UIControlStateNormal &
UIControlStateHighlighted &
UIControlStateSelected];
}
You have to set the titleColorfor normal, highlight and selected UIControlStatebecause there can be more than one state at a time according to the documentation of UIControlState.
If you don't create these methods, the UIButtonwill display selection or highlighting but they won't stay in the UIColoryou setup inside the UIInterface Builderbecause they are just available for a short display of a selection, not for displaying selection itself.
您必须设置titleColorfor normal、highlight 和 selected，UIControlState因为根据UIControlState. 如果您不创建这些方法，它们UIButton将显示选择或突出显示，但它们不会保留在UIColor您设置的内部，UIInterface Builder因为它们仅可用于简短显示选择，而不用于显示选择本身。

在斯威夫特：
Changing the label text color is quite different than changing it for a UIButton. To change the text color for a UIButtonuse this method:
更改标签文本颜色与更改UIButton. 要更改UIButton使用此方法的文本颜色：
self.headingButton.setTitleColor(UIColor(red: 107.0/255.0, green: 199.0/255.0, blue: 217.0/255.0), forState: UIControlState.Normal)
