首先初始化你的 NSString 和 NSMutableAttributedString,如下所示。
var myString:NSString = "I AM KIRIT MODI"
var myMutableString = NSMutableAttributedString()
在ViewDidLoad
override func viewDidLoad() {
myMutableString = NSMutableAttributedString(string: myString, attributes: [NSFontAttributeName:UIFont(name: "Georgia", size: 18.0)!])
myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.redColor(), range: NSRange(location:2,length:4))
// set label Attribute
labName.attributedText = myMutableString
super.viewDidLoad()
}
输出
多种颜色
在您的 ViewDidLoad 中添加以下行代码以获取字符串中的多种颜色。
myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.greenColor(), range: NSRange(location:10,length:5))
多色输出
