How to remove UIButton selected background color?
提问by TommyG
I am looking for a solution to this problem that does NOT require using images/PNGs. I am looking for a way to remove the UIButton's blue background color when it's in selected state, and I just cannot find a way to do that without using images. I am basically trying to do something like that in case of a UITableViewCell:
我正在寻找不需要使用图像/PNG 的解决方案。我正在寻找一种方法来UIButton在它处于选定状态时删除的蓝色背景颜色，但我找不到不使用图像的方法。我基本上是在尝试做类似的事情，以防万一UITableViewCell：
cell.selectionStyle = UITableViewCellSelectionStyleNone;

Unfortunately I'm away from my test machine at the moment, but there are two things you could try.
不幸的是，我目前不在我的测试机旁，但是您可以尝试两件事。
First would be to set the following property:
首先是设置以下属性：
button.adjustsImageWhenHighlighted = NO;
Or uncheck "Highlight adjusts image" in Interface Builder.
或者在 Interface Builder 中取消选中“突出显示调整图像”。
If that doesn't work like you expect it to, you can deselect the button in the action you tied it to, like so:
如果这不像您期望的那样工作，您可以在绑定它的操作中取消选择按钮，如下所示：
- (IBAction)yourButtonAction:(id)sender {
[sender setHighlighted:NO];
}

I had this same issue and I resolve it by changing the UIButton type from "System" to "Custom". The blue background color does not show up in selected state when it is a "Custom" type.
我遇到了同样的问题，我通过将 UIButton 类型从“系统”更改为“自定义”来解决它。当它是“自定义”类型时，蓝色背景颜色不会在选定状态下显示。

Change the alpha of the tintColor to zero, works if iOS is 5.0 or later
将 tintColor 的 alpha 更改为零，适用于 iOS 5.0 或更高版本
UIColor *color = [[UIColor alloc] initWithRed:0.0 green:0.0 blue:0.0 alpha:0.0];
button.tintColor = color;

Very simple, in storyBoard, select your UIButtonand open attribute inspector. Now scroll down to Viewsection and change Tintproperty to Clear Coloror any specific color if u want.
很简单，在storyBoard，选择你的UIButton并打开attribute inspector。现在向下滚动到View部分并根据需要将Tint属性更改为Clear Color或任何特定颜色。

UIButton also with customtype, we can set it in xcodeas-
UIButton 也有custom类型，我们可以将它设置为xcode-
ORBy programmatically as-
或以编程方式作为-
let customButton = UIButton(type: .custom)
customButton.setTitle("this is Button", for: .normal)
customButton.setTitleColor(UIColor.blue, for: .normal)
customButton.frame = CGRect(x: 15, y: 50, width: 300, height: 500)
self.view.addSubview( customButton)
Now there is no more UIButton's blue background color
现在不再有UIButton 的蓝色背景色了

Not a direct answer to OP's question but to remove this colour in a UIButtonsubclass you can do this:
不是对 OP 问题的直接回答，而是要在UIButton子类中删除此颜色，您可以执行以下操作：
override func layoutSubviews() {
tintColor = .clear
super.layoutSubviews()
}

What did it for me was changing the button.tintColor in the highlighted state. This is swift 3, iOS 10
对我来说是什么改变了突出显示状态的 button.tintColor。这是 swift 3, iOS 10
override public var isHighlighted: Bool {
didSet {
self.tintColor = UIColor(red: 255/255, green: 255/255, blue: 255/255, alpha: 1.0)
}
}
Or you can do the same in the interface builder
或者您可以在界面构建器中执行相同操作

Not sure if this is the best way. But you could have an invisible button or view ontop of the actual button then recognize when the top button/view has been clicked.
不确定这是否是最好的方法。但是您可以在实际按钮的顶部有一个不可见的按钮或视图，然后识别何时单击了顶部按钮/视图。
