按下按钮时改变文字颜色?

I know how to change the background color but what about the actual text? There doesn't seem to be a member on a UIButton called "color" or anything like that. My code:

我知道如何改变背景颜色，但是实际的文本呢?似乎UIButton中没有一个成员叫做"color"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

    }

2 个解决方案

#1

There is no property setter color in UIButton. use instead setTitleColor.Write this in viewWillAppear

UIButton中没有属性setter颜色。使用相反setTitleColor。写这篇文章进行处理

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

This will change title color to brown for UIControlState.Normal

这将把uicontrolstate的标题颜色改为棕色

To set the color of title when button is in Highlighted state use

当按钮处于突出显示状态时，设置标题的颜色

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

Swift 3.0 example:

斯威夫特3.0的例子:

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