我只是创建了UILabel的一个子类来专门处理这样的用例。您可以轻松地添加多个链接并为它们定义不同的处理程序。它还支持突出显示按下的链接时，你触摸触摸反馈。请参考https://github.com/null09264/FRHyperLabel。

在你的例子中，代码可能是这样的:

FRHyperLabel *label = [FRHyperLabel new];

NSString *string = @"This morph was generated with Face Dancer, Click to view in the app store.";
NSDictionary *attributes = @{NSFontAttributeName: [UIFont preferredFontForTextStyle:UIFontTextStyleHeadline]};

label.attributedText = [[NSAttributedString alloc]initWithString:string attributes:attributes];

[label setLinkForSubstring:@"Face Dancer" withLinkHandler:^(FRHyperLabel *label, NSString *substring){
    [[UIApplication sharedApplication] openURL:aURL];
}];

示例截图(在这种情况下，处理程序被设置为弹出警报而不是打开url)

如果你想在UITextView中使用NSLinkAttributeName，那么你可以考虑使用AttributedTextView库。它是一个UITextView子类，它让处理这些变得很容易。更多信息请参见:https://github.com/evermeer/AttributedTextView

你可以让文本的任何部分像这样交互(其中textView1是一个UITextView IBoutlet):

textView1.attributer =
    "1. ".red
    .append("This is the first test. ").green
    .append("Click on ").black
    .append("evict.nl").makeInteract { _ in
        UIApplication.shared.open(URL(string: "http://evict.nl")!, options: [:], completionHandler: { completed in })
    }.underline
    .append(" for testing links. ").black
    .append("Next test").underline.makeInteract { _ in
        print("NEXT")
    }
    .all.font(UIFont(name: "SourceSansPro-Regular", size: 16))
    .setLinkColor(UIColor.purple) 

为了处理标签和提及，你可以使用这样的代码:

textView1.attributer = "@test: What #hashtags do we have in @evermeer #AtributedTextView library"
    .matchHashtags.underline
    .matchMentions
    .makeInteract { link in
        UIApplication.shared.open(URL(string: "https://twitter.com\(link.replacingOccurrences(of: "@", with: ""))")!, options: [:], completionHandler: { completed in })
    }

如果你有@Karl Nosworthy和@esilver上面提供的问题，我已经更新了NSMutableAttributedString扩展到它的Swift 4版本。

extension NSMutableAttributedString {

public func setAsLink(textToFind:String, linkURL:String) -> Bool {

    let foundRange = self.mutableString.range(of: textToFind)
    if foundRange.location != NSNotFound {
         _ = NSMutableAttributedString(string: textToFind)
        // Set Attribuets for Color, HyperLink and Font Size
        let attributes = [NSFontAttributeName: UIFont.bodyFont(.regular, shouldResize: true), NSLinkAttributeName:NSURL(string: linkURL)!, NSForegroundColorAttributeName: UIColor.blue]

        self.setAttributes(attributes, range: foundRange)
        return true
    }
    return false
  }
}

使用UITextView并为Link设置dataDetectorTypes。

是这样的:

testTextView.editable = false 
testTextView.dataDetectorTypes = .link

如果你想检测链接，电话号码，地址等

testTextView.dataDetectorTypes = .all

Swift版本:

    // Attributed String for Label
    let plainText = "Apkia"
    let styledText = NSMutableAttributedString(string: plainText)
    // Set Attribuets for Color, HyperLink and Font Size
    let attributes = [NSFontAttributeName: UIFont.systemFontOfSize(14.0), NSLinkAttributeName:NSURL(string: "http://apkia.com/")!, NSForegroundColorAttributeName: UIColor.blueColor()]
    styledText.setAttributes(attributes, range: NSMakeRange(0, plainText.characters.count))
    registerLabel.attributedText = styledText

我需要继续使用一个纯的UILabel，所以从我的点击识别器称为这(这是基于malex的响应在这里:字符索引在触摸点UILabel)

UILabel* label = (UILabel*)gesture.view;
CGPoint tapLocation = [gesture locationInView:label];

// create attributed string with paragraph style from label

NSMutableAttributedString* attr = [label.attributedText mutableCopy];
NSMutableParagraphStyle* paragraphStyle = [NSMutableParagraphStyle new];
paragraphStyle.alignment = label.textAlignment;

[attr addAttribute:NSParagraphStyleAttributeName value:paragraphStyle range:NSMakeRange(0, label.attributedText.length)];

// init text storage

NSTextStorage *textStorage = [[NSTextStorage alloc] initWithAttributedString:attr];
NSLayoutManager *layoutManager = [[NSLayoutManager alloc] init];
[textStorage addLayoutManager:layoutManager];

// init text container

NSTextContainer *textContainer = [[NSTextContainer alloc] initWithSize:CGSizeMake(label.frame.size.width, label.frame.size.height+100) ];
textContainer.lineFragmentPadding  = 0;
textContainer.maximumNumberOfLines = label.numberOfLines;
textContainer.lineBreakMode        = label.lineBreakMode;

[layoutManager addTextContainer:textContainer];

// find tapped character

NSUInteger characterIndex = [layoutManager characterIndexForPoint:tapLocation
                                                  inTextContainer:textContainer
                         fractionOfDistanceBetweenInsertionPoints:NULL];

// process link at tapped character

[attr enumerateAttributesInRange:NSMakeRange(characterIndex, 1)
                                         options:0
                                      usingBlock:^(NSDictionary<NSString *,id> * _Nonnull attrs, NSRange range, BOOL * _Nonnull stop) {
                                          if (attrs[NSLinkAttributeName]) {
                                              NSString* urlString = attrs[NSLinkAttributeName];
                                              NSURL* url = [NSURL URLWithString:urlString];
                                              [[UIApplication sharedApplication] openURL:url];
                                          }
                                      }];
