按下按钮时更改文本的颜色？

Question

我知道如何更改背景颜色,但实际文本呢？UIButton上似乎没有成员称为"颜色"或类似的东西.我的代码:

@IBAction func yellowBtnClicked(sender: UIButton) {
        gameboard.image = UIImage(named: "Yellow_gb")
        resultsView.image = UIImage(named: "Yellow_results")
        colorsView.image = UIImage(named: "Yellow_colors")
        colorsBtn.color = UIColor.brownColor() //This line has the issue

    }

Answer 1

没有的属性设置color在UIButton.改为使用.setTitleColor写入viewWillAppear

colorsBtn.setTitleColor(UIColor.brownColor(), forState: UIControlState.Normal)

这会将标题颜色更改为棕色 UIControlState.Normal

设置title按钮处于Highlighted状态时的颜色

colorsBtn.setTitleColor(UIColor.brownColor(), forState: UIControlState.Highlighted)

Answer 2

Swift 3.0示例:

    colorsBtn.setTitleColor(UIColor .white, for: UIControlState.normal)
    colorsBtn.setTitleColor(UIColor .black, for: UIControlState.highlighted)
