對於 Label 需要支援複製、超連結監聽最好的方案就是使用UITextView 代替Label 

設定TextView支援超連結

self.contentTextView.textContainerInset = UIEdgeInsetsMake(0, 0, 0, 0);self.contentTextView.delegate = self;self.contentTextView.editable = NO;self.contentTextView.showsVerticalScrollIndicator = NO;self.contentTextView.dataDetectorTypes = UIDataDetectorTypeLink; 

　　

TextView  預設超連結點擊 是應用外跳轉要想實現應用內跳轉，需要遵循 UITextViewDelegate 實現UITextViewDelegate代理方法，攔截到超連結URL 自己在應用內做跳轉 

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {    if ([self.delegate respondsToSelector:@selector(clickUrl:)]) {        [self.delegate clickUrl:[URL.absoluteString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];    }    NSLog(@"%@", URL.absoluteString);    return NO;  }

　　

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange   return YES 除了監聽點擊事件之外還是監聽長按事件 長按彈出copy share 按鈕 ，不過點擊open 會跳轉到應用外開啟連結，return NO  只監聽連結的點擊事件  不監聽其他事件  例如長按彈出copy share 按鈕 ， 這樣我們可以自訂 退出鍵 ，然後做copy 和 應用內開啟連結等操作 

- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {    if ([self.delegate respondsToSelector:@selector(clickUrl:)]) {        [self.delegate clickUrl:[URL.absoluteString stringByReplacingPercentEscapesUsingEncoding:NSUTF8StringEncoding]];    }    return NO;}

　　

控制器裡面 實現代理

- (void)clickUrl:(NSString *)url {    UIAlertControllerStyle style = UIAlertControllerStyleActionSheet;    if ([PhoneUtil isPadDevice]) {    // 適配iPad         style = UIAlertControllerStyleAlert;    }    UIAlertController *alertVC = [UIAlertController alertControllerWithTitle:url message:nil preferredStyle:style];    // 處理複製    UIAlertAction *copyAction = [UIAlertAction actionWithTitle:getStringByKey(@"string_key_616") style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {        UIPasteboard *pasteboard = [UIPasteboard generalPasteboard];        pasteboard.string = url;    }];    // 處理連結點擊應用內跳轉    UIAlertAction *openAction = [UIAlertAction actionWithTitle:getStringByKey(@"string_key_1370") style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {        UIStoryboard *sb=[UIStoryboard storyboardWithName:@"Setting" bundle:[NSBundle mainBundle]];        WebViewVC *vc=[sb instantiateViewControllerWithIdentifier:@"WebViewVC"];        vc.url = url;        [self.navigationController pushViewController:vc animated:YES];    }];    UIAlertAction *cancelAction = [UIAlertAction actionWithTitle:getStringByKey(@"string_key_219") style:UIAlertActionStyleCancel handler:nil];        [alertVC addAction:copyAction];    [alertVC addAction:openAction];    [alertVC addAction:cancelAction];    [self.navigationController presentViewController:alertVC animated:YES completion:nil];}
