label添加下划线以及实现添加点击事件(支持xib或者sb)

使用案例:

     NSString *text = @"已阅读并同意《发标授权协议》《代扣协议》";
     __weak typeof(self)weakSelf = self;
    [self.lbl_Content attributeLinkLabelText:text withLinksAttribute:nil  
    withActiveLinkAttributes:nil withLinkClickCompleteHandler:^(NSInteger linkedURLTag) {
         __strong typeof(weakSelf)strongSelf = weakSelf;
        strongSelf.lbl_Result.text = [NSString stringWithFormat:@"当前点击的tag%ld",linkedURLTag];
        NSLog(@"linkedURLTag =%ld",linkedURLTag); 
    } withUnderLineTextString:@"《发标授权协议》",@"《代扣协议》",nil];
