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

使用UITextView它支持可点击链接。 使用以下代码创建带属性的字符串

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:strSomeTextWithLinks];

然后设置UITextView text，如下所示

NSDictionary *linkAttributes = @{NSForegroundColorAttributeName: [UIColor redColor],

                                 NSUnderlineColorAttributeName: [UIColor blueColor],

                                 NSUnderlineStyleAttributeName: @(NSUnderlinePatternSolid)};

customTextView.linkTextAttributes = linkAttributes; // customizes the appearance of links
textView.attributedText = attributedString;

确保你在XIB中启用了UITextView的“可选”行为。

我也有类似的需求，最初我使用UILabel，然后我意识到UITextView更好。我使UITextView行为像UILabel通过禁用交互和滚动，并为NSMutableAttributedString做了一个类别方法来设置链接到文本，就像Karl所做的一样(+1)这是我的obj c版本

-(void)setTextAsLink:(NSString*) textToFind withLinkURL:(NSString*) url
{
    NSRange range = [self.mutableString rangeOfString:textToFind options:NSCaseInsensitiveSearch];

    if (range.location != NSNotFound) {

        [self addAttribute:NSLinkAttributeName value:url range:range];
        [self addAttribute:NSForegroundColorAttributeName value:[UIColor URLColor] range:range];
    }
}

您可以使用下面的委托来处理该操作

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)url inRange:(NSRange)characterRange
{
    // do the task
    return YES;
}

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

我写了一个方法，添加一个链接(linkString)到一个字符串(fullString)与特定的url(urlString):

- (NSAttributedString *)linkedStringFromFullString:(NSString *)fullString withLinkString:(NSString *)linkString andUrlString:(NSString *)urlString
{
    NSRange range = [fullString rangeOfString:linkString options:NSLiteralSearch];
    NSMutableAttributedString *str = [[NSMutableAttributedString alloc] initWithString:fullString];

    NSMutableParagraphStyle *paragraphStyle = NSMutableParagraphStyle.new;
    paragraphStyle.alignment = NSTextAlignmentCenter;
    NSDictionary *attributes = @{NSForegroundColorAttributeName:RGB(0x999999),
                                 NSFontAttributeName:[UIFont fontWithName:@"HelveticaNeue-Light" size:10],
                                 NSParagraphStyleAttributeName:paragraphStyle};
    [str addAttributes:attributes range:NSMakeRange(0, [str length])];
    [str addAttribute: NSLinkAttributeName value:urlString range:range];

    return str;
}

你应该这样称呼它:

NSString *fullString = @"A man who bought the Google.com domain name for $12 and owned it for about a minute has been rewarded by Google for uncovering the flaw.";
NSString *linkString = @"Google.com";
NSString *urlString = @"http://www.google.com";

_youTextView.attributedText = [self linkedStringFromFullString:fullString withLinkString:linkString andUrlString:urlString];

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 })
    }
