TTTAttributedLabe作为UILabel的替代，可以轻松的渲染可变字符串，文中中加入嵌入链接，手机号，时间都可以得到相对应的处理，项目地址TTTAttributedLabel,简单看一下效果:

普通Label:

    UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(20, 100, 200, 50)];
    label.textColor       = [UIColor whiteColor];
    label.text            = @"美国职业篮球联赛（National Basketball Association，简称NBA，中文简称“美职篮”）于1946年6月6日在纽约成立，是由北美三十支队伍组成的男子职业篮球联盟，美国四大职业体育...";
    label.backgroundColor = [UIColor redColor];
    label.font            = [UIFont systemFontOfSize:14];
    label.numberOfLines   = 0;
    label.lineBreakMode   = NSLineBreakByWordWrapping;
    [self.view addSubview:label];

TTTAttributedLabel中的FlyElephant链接设置:

    NSString           *text  = @"美国职业篮球联赛（National Basketball Association，简称NBA，中文简称“美职篮”）于1946年6月6日在纽约成立(FlyElephant)，是由北美三十支队伍组成的男子职业篮球联盟，美国四大职业体育...";
    TTTAttributedLabel *label = [[TTTAttributedLabel alloc] initWithFrame:CGRectMake(20, 180, 300, 100)];
    label.textColor = [UIColor whiteColor];
    
    NSMutableAttributedString *atributeStr = [[NSMutableAttributedString alloc] initWithString:text attributes:@{
                                                  NSForegroundColorAttributeName:[UIColor whiteColor],
                                                  NSFontAttributeName :[UIFont systemFontOfSize:14]
                                              }];
    label.text            = atributeStr;
    label.backgroundColor = [UIColor redColor];
    label.font            = [UIFont systemFontOfSize:14];
    label.numberOfLines   = 0;
    label.linkAttributes       = @{NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName:[UIFont systemFontOfSize:16.0f]};
    label.activeLinkAttributes = @{NSForegroundColorAttributeName:[UIColor blackColor], NSFontAttributeName:[UIFont systemFontOfSize:16.0f]};
    NSRange serviceRange = [text rangeOfString:@"FlyElephant"];
    label.delegate = self;
    [self.view addSubview:label];
    [label addLinkToURL:[NSURL URLWithString:@"http://www.jianshu.com/users/24da48b2ddb3/latest_articles"] withRange:serviceRange];

实现TTTAttributedLabelDelegate协议:

-(void)attributedLabel:(TTTAttributedLabel *)label didSelectLinkWithURL:(NSURL *)url {
    [[UIApplication sharedApplication] openURL:url];
}

如果加入了其他手势操作，会导致TTTAttributedLabel中的链接无法响应，因此需要在手势的delegate中进行判断:

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:(UITouch *)touch {
    if ([touch.view isKindOfClass:[TTTAttributedLabel class]]) {
        return NO;
    }
    return YES;
}
