Change color of text when button is pushed?
提问by skyguy
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:
我知道如何更改背景颜色，但实际文本呢？UIButton 上似乎没有名为“颜色”或类似名称的成员。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
}

There is no property setter colorin UIButton. use instead setTitleColor.Write this in viewWillAppear
没有的属性设置color在UIButton。改用setTitleColor.Write this inviewWillAppear
colorsBtn.setTitleColor(UIColor.brownColor(), forState: UIControlState.Normal)
This will change title color to brown for UIControlState.Normal
这会将标题颜色更改为棕色 UIControlState.Normal
To set the color of titlewhen button is in Highlightedstate use
设置title按钮处于Highlighted状态时的颜色使用
colorsBtn.setTitleColor(UIColor.brownColor(), forState: UIControlState.Highlighted)
