Ios 在单个标签中使用多种字体 colored颜色

发布于01月01日

在iOS中，有没有办法在一个标签中使用两种、甚至三种字体 colored颜色？

如果以文字"hello，are are you"为例，那么"hello"将是蓝色的，而"hello are you"将是绿色的.

这是可能的吗，这看起来比创建多个标签更容易吗？

推荐答案

首先，初始化NSString和NSMutableAttributedString，如下所示.

var myString:NSString = "I AM KIRIT MODI"
var myMutableString = NSMutableAttributedString()

在ViewDidLoad个月内

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()
}

OUTPUT

MULTIPLE COLOR个

在ViewDidLoad中添加下面的行代码，以获得字符串中的多种 colored颜色 .

 myMutableString.addAttribute(NSForegroundColorAttributeName, value: UIColor.greenColor(), range: NSRange(location:10,length:5))

Multiple color OUTPUT

Swift 4个

var myMutableString = NSMutableAttributedString(string: str, attributes: [NSAttributedStringKey.font :UIFont(name: "Georgia", size: 18.0)!])
myMutableString.addAttribute(NSAttributedStringKey.foregroundColor, value: UIColor.red, range: NSRange(location:2,length:4))

Swift 5.0个

 var myMutableString = NSMutableAttributedString(string: str, attributes: [NSAttributedString.Key.font :UIFont(name: "Georgia", size: 18.0)!])
 myMutableString.addAttribute(NSAttributedString.Key.foregroundColor, value: UIColor.red, range: NSRange(location:2,length:4))
