UIButton will highlighted on click, so check button setting Change the title color in highlight state config to same as default state Or you can set:
UIButton 将在单击时突出显示，因此请检查按钮设置将突出显示状态配置中的标题颜色更改为与默认状态相同，或者您可以设置：
[button setTitleColor:[UIColor blackColor] forState:UIControlStateHighlighted];
If you want to control Highlighted by code, you can disable normal highlighted by subclass Button and disable in touchesBegin:
如果你想通过代码来控制高亮，你可以禁用子类Button的正常高亮并在touchesBegin中禁用：
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event{
if (self.state == UIControlStateHighlighted) {
[self setHighlighted:NO];
}
}

You could also make the UIButton type : custom from StoryBoard
您还可以制作 UIButton 类型：来自 StoryBoard 的自定义
This should strip down any system behavior for you. (I think)
这应该为您剥离任何系统行为。（我认为）

This is a solution for buttons that have images. In the storyboard, there is a property called HighlightedAdjustsImagewhich is On by default. Disable that and your button image will not show any highlighted properties.
这是具有图像的按钮的解决方案。在故事板中，有一个名为的属性HighlightedAdjustsImage，默认情况下为 On。禁用它，您的按钮图像将不会显示任何突出显示的属性。

Just uncheck "Highlighted Adjust Image"and if you want to remove disabled background uncheck "Disabled Adjust Image"too.
只需取消选中“突出显示的调整图像”，如果您想删除禁用的背景，也不要选中“禁用的调整图像”。
First ensure your button type is "Custom"
首先确保您的按钮类型是“自定义”

None of the solutions I found online worked for me (including these ones listed here), so I ended up doing this in my custom UIButtonsubclass:
我在网上找到的所有解决方案都不适合我（包括此处列出的这些），因此我最终在我的自定义UIButton子类中执行了此操作：
// swift:
override var isHighlighted: Bool {
didSet { if isHighlighted { isHighlighted = false } }
}
I also have the buttonTypeset to .custom, but it probably makes no difference here.
我也有buttonType设置为.custom，但在这里可能没有区别。
And now: no more weird highlighting or colour animations!
现在：不再有奇怪的突出显示或彩色动画！

My 2 cents ;) Swift 3 ready
我的 2 美分 ;) Swift 3 准备好了
class CustomButton: UIButton {
override var isHighlighted: Bool {
didSet {
if (isHighlighted) {
super.isHighlighted = false
}
}
}
}
Situation and History
情况和历史
I had set images for UIControlState.normaland UIControlState.selected, so setting UIButton.isSelected = trueshows selected image, else the normal image.
我已经为UIControlState.normal和设置了图像UIControlState.selected，因此设置UIButton.isSelected = true显示所选图像，否则显示正常图像。
The issue we discovered was when UIButton.isSelected = true, and during highlight/focus (by tap hold the button and discard tap by swiping away)button shows image for UIControlState.normal, that looked pretty ugly to my boss :D
我们发现的问题是UIButton.isSelected = true在高亮/聚焦期间（通过点击按住按钮并通过滑动放弃点击）按钮显示 的图像UIControlState.normal，这对我的老板来说看起来很丑陋：D
I tried several solutions, such as UIButton(type: UIButtonType.custom)and UIButton.adjustsImageWhenHighlighted = false, none helped :(
我尝试了几种解决方案，例如UIButton(type: UIButtonType.custom)and UIButton.adjustsImageWhenHighlighted = false，都没有帮助:(
