无法在 swift 中的循环内更改 textColor 和字体大小

Question

我不知道为什么字体大小和文本颜色在循环中没有任何效果...有人帮忙吗？？这是我的代码：

var buttons = ["N","F","S","D","C","A","R"]


    for button in buttons
        {

            var Button:UIButton = UIButton()

            Button = UIButton(frame: CGRect(x:10, y: 20, width: 80, height: 80))
            Button.frame.origin = ButtonPosition
            ButtonPosition.x = ButtonPosition.x + buttonIncrement
            Button.layer.cornerRadius = 3
            Button.clipsToBounds = true
            Button.backgroundColor = UIColor.groupTableViewBackgroundColor()
            Button.setTitle("\(button)", forState: UIControlState.Normal)
            Button.titleLabel?.text = "\(button)"
            Button.titleLabel?.font = UIFont(name:"Chalkboard SE Regular", size: 30)
            Button.titleLabel?.textColor = UIColor.blackColor()
            Button.setBackgroundImage(UIImage.imageWithColor(UIColor.colorWithHex("#b8b4af", alpha: 0.5)), forState: .Highlighted)

            Button.addTarget(self, action: "check:", forControlEvents: UIControlEvents.TouchUpInside)

        buttonView.addSubview(Button)  

    }

    return buttonView

Answer 1

您应该直接编辑按钮，而不是 titleLabel，像这样：

Button.setTitle("\(button)", forState: .Normal)
Button.setTitleColor(UIColor.blackColor(), forState: .Normal)

Answer 2

首先删除行Button.titleLabel?.text = "\(button)"。这个就够了Button.setTitle("\(button)", forState: UIControlState.Normal).

那么你应该使用按钮中的 setTitleColor 方法来改变它。 Button.setTitleColor(UIColor. blackColor(), forState: UIControlState.Normal)

最后你的字体名称弄错了： Button.titleLabel?.font = UIFont(name:"ChalkboardSE-Regular", size: 30.0)

就是这样！
