颜色着色UIButton图像

I noticed that when I place a white or black UIImage into a UISegmentedControl it automatically color masks it to match the tint of the segmented control. I thought this was really cool, and was wondering if I could do this elsewhere as well. For example, I have a bunch of buttons that have a uniform shape but varied colors. Instead of making a PNG for each button, could I somehow use this color masking to use the same image for all of them but then set a tint color or something to change their actual color?

Swift 4与customType:

let button = UIButton(frame: aRectHere)
    let buttonImage = UIImage(named: "imageName")
    button.setImage(buttonImage?.withRenderingMode(.alwaysTemplate), for: .normal)
    button.tintColor = .white

    let image = UIImage(named:"NoConnection")!

 warningButton = UIButton(type: .system)        
    warningButton.setImage(image, for: .normal)
    warningButton.tintColor = UIColor.lightText
    warningButton.frame = CGRect(origin: CGPoint(x:-100,y:0), size: CGSize(width: 59, height: 56))

    self.addSubview(warningButton)

以上都不适合我，因为点击后色调被清除。我必须使用

button.setImageTintColor(Palette.darkGray(), for: UIControlState())

改变按钮图像或图像视图色调颜色

btn.imageView?.image = btn.imageView?.image?.withRenderingMode(.alwaysTemplate)

btn.imageView?.tintColor = #colorLiteral(red: 0, green: 0, blue: 0, alpha: 1)

为了在按钮上设置白色的图像(箭头图标)，我们使用:

let imageOnButton = UIImage(named: "navForwardArrow")?.imageWithColor(color: UIColor.white)
button.setImage(imageOnButton, for: .normal)

已知问题:当按下按钮时，图标会失去白色。

自定义按钮以各自的图像颜色显示。在故事板中将按钮类型设置为“System”(或者在代码中设置为UIButtonTypeSystem)，将以默认的色调呈现按钮的图像。

(在iOS9, Xcode 7.3上测试)
