    _textView = [[UITextView alloc] initWithFrame:CGRectMake(14, 220, SCREEN_WIDTH -24, 100)];
    _textView.backgroundColor = [UIColor clearColor];

    //添加链接
    _textView.linkTextAttributes = linkAttributes;
    _textView.attributedText = attributedString;
//    _textView.delegate = self;
    _textView.editable = NO;   // 非编辑状态下才可以点击Url

代理方法处理点击事件

//这里可以对点击事件进行操作
- (BOOL)textView:(UITextView *)textView shouldInteractWithURL:(NSURL *)URL inRange:(NSRange)characterRange {
    if ([[URL scheme] isEqualToString:@"www"]) {
//        NSString *urlhost = [URL host];
        return NO;
    }
    return YES;
}
