我在这个问题中学到了 NAlexN 的答案（在 UILabel 的 NSAttributedString 中创建可点击的“链接”？），并自己编写了一个演示。然而，我很不幸地完成了这个演示。这是我的代码：（大家可以直接将以下代码复制到新项目中进行测试）

#import "ViewController.h"

@interface ViewController ()

    NSTextContainer *textContainer;
    NSLayoutManager *layoutManager;

    label.userInteractionEnabled = YES;
    UITapGestureRecognizer*  tap=[[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(handleTapOnLabel:)];
    [tap setNumberOfTapsRequired:1];
    [label addGestureRecognizer:tap];
    [self.view addSubview:label];

    NSMutableAttributedString *attributedString =[[NSMutableAttributedString alloc] initWithString:@"String with a link" attributes:nil];
    NSRange linkRange = NSMakeRange(14, 4); // for the word "link" in the string above
    NSDictionary *linkAttributes = @{ NSForegroundColorAttributeName …
