swift - 如何在 Swift 中为状态设置属性标题颜色

Question

我可以为 UIControlState 设置 attributedTitle，但是如何为 UIControlState 设置属性标题的颜色？

Answer 1

// create the button
let button = UIButton(frame: CGRect(x: 0, y: 0, width: 100, height: 50))
button.backgroundColor = UIColor.yellowColor()

// set the attributed title for different states

// .Selected
let mySelectedAttributedTitle = NSAttributedString(string: "Click Here",
    attributes: [NSForegroundColorAttributeName : UIColor.greenColor()])
button.setAttributedTitle(mySelectedAttributedTitle, forState: .Selected)

// .Normal
let myNormalAttributedTitle = NSAttributedString(string: "Click Here",
    attributes: [NSForegroundColorAttributeName : UIColor.blueColor()])
button.setAttributedTitle(myNormalAttributedTitle, forState: .Normal)
