在单个标签中使用多种字体颜色 [英] Use multiple font colors in a single label

问题描述

有没有办法在iOS中的单个标签中使用两种甚至三种字体颜色？

Is there a way to use two, or even three font colors in a single label in iOS?

如果使用你好，你好吗这样的文字作为例子，你好将是蓝色，你好吗将是绿色？

If the text "hello, how are you" were used as an example, the "hello," would be blue, and the "how are you" would be green?

这可能，比创建多个标签更容易吗？

Is this possible, it seems easier than creating multiple labels?

推荐答案

首先初始化你 NSString 和 NSMutableAttributedString ，如下所示。

First of all initialize of you NSString and NSMutableAttributedString as below.

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()
}

**您的输出：**

多种颜色

在ViewDidLoad中添加以下行代码以获取字符串中的多种颜色。
