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

一个快速增加邓肯C的原始描述-á-vie IB行为。他写道:“在UITextView中创建可点击的超链接很简单。你只需在IB的视图上设置“检测链接”复选框，它就会检测http链接并将它们转换为超链接。”

我的经验(至少在xcode 7)是，你还必须取消“可编辑”行为的url被检测和可点击。

我发现这真的很有用，但我需要在相当多的地方这样做，所以我已经包装了我的方法在一个简单的扩展到NSMutableAttributedString:

斯威夫特3

extension NSMutableAttributedString {

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

        let foundRange = self.mutableString.range(of: textToFind)
        if foundRange.location != NSNotFound {
            self.addAttribute(.link, value: linkURL, range: foundRange)
            return true
        }
        return false
    }
}

斯威夫特2

import Foundation

extension NSMutableAttributedString {

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

       let foundRange = self.mutableString.rangeOfString(textToFind)
       if foundRange.location != NSNotFound {
           self.addAttribute(NSLinkAttributeName, value: linkURL, range: foundRange)
           return true
       }
       return false
   }
}

使用示例:

let attributedString = NSMutableAttributedString(string:"I love stackoverflow!")
let linkWasSet = attributedString.setAsLink("stackoverflow", linkURL: "http://stackoverflow.com")

if linkWasSet {
    // adjust more attributedString properties
}

objective - c

我只是满足了在纯Objective-C项目中做同样事情的要求，这里是Objective-C类别。

@interface NSMutableAttributedString (SetAsLinkSupport)

- (BOOL)setAsLink:(NSString*)textToFind linkURL:(NSString*)linkURL;

@end


@implementation NSMutableAttributedString (SetAsLinkSupport)

- (BOOL)setAsLink:(NSString*)textToFind linkURL:(NSString*)linkURL {

     NSRange foundRange = [self.mutableString rangeOfString:textToFind];
     if (foundRange.location != NSNotFound) {
         [self addAttribute:NSLinkAttributeName value:linkURL range:foundRange];
         return YES;
     }
     return NO;
}

@end

使用示例:

NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:"I love stackoverflow!"];

BOOL linkWasSet = [attributedString setAsLink:@"stackoverflow" linkURL:@"http://stackoverflow.com"];

if (linkWasSet) {
    // adjust more attributedString properties
}

确保NSTextField的Behavior属性被设置为Selectable。

只需为UITextView找到一个无代码的解决方案:

启用检测->链接选项，URL和电子邮件也将被检测和点击!

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)

Swift 3的例子，以检测对属性文本点击的动作

https://stackoverflow.com/a/44226491/5516830

let termsAndConditionsURL = TERMS_CONDITIONS_URL;
let privacyURL            = PRIVACY_URL;

override func viewDidLoad() {
    super.viewDidLoad()

    self.txtView.delegate = self
    let str = "By continuing, you accept the Terms of use and Privacy policy"
    let attributedString = NSMutableAttributedString(string: str)
    var foundRange = attributedString.mutableString.range(of: "Terms of use") //mention the parts of the attributed text you want to tap and get an custom action
    attributedString.addAttribute(NSLinkAttributeName, value: termsAndConditionsURL, range: foundRange)
    foundRange = attributedString.mutableString.range(of: "Privacy policy")
    attributedString.addAttribute(NSLinkAttributeName, value: privacyURL, range: foundRange)
    txtView.attributedText = attributedString
}

func textView(_ textView: UITextView, shouldInteractWith URL: URL, in characterRange: NSRange) -> Bool {
    let storyboard = UIStoryboard(name: "Main", bundle: nil)
    let vc = storyboard.instantiateViewController(withIdentifier: "WebView") as! SKWebViewController

    if (URL.absoluteString == termsAndConditionsURL) {
        vc.strWebURL = TERMS_CONDITIONS_URL
        self.navigationController?.pushViewController(vc, animated: true)
    } else if (URL.absoluteString == privacyURL) {
        vc.strWebURL = PRIVACY_URL
        self.navigationController?.pushViewController(vc, animated: true)
    }
    return false
}

同样，你可以用shouldInteractWith URLUITextFieldDelegate方法添加任何你想要的动作。

干杯! !
