一个带下划线的UILabel，当然下划线可有可无。

写完之后恍然大明白。给label加个手势不得了。于是应运而生。

 UILabel *labClicked                               = [[UILabel alloc] initWithFrame:CGRectMake(60, 0,  60, 60)];
labClicked.backgroundColor                        = [UIColor redColor];
labClicked.text                                   = @"阿三";
labClicked.userInteractionEnabled                 = YES;
UITapGestureRecognizer *labelTapGestureRecognizer = [[UITapGestureRecognizer alloc]initWithTarget:self action:@selector(labelTouchUpInside:)];

[labClicked addGestureRecognizer:labelTapGestureRecognizer];
[self.view addSubview:labClicked];

华丽分割线------------------------

-(void) labelTouchUpInside:(UITapGestureRecognizer *)recognizer{

UILabel *label=(UILabel*)recognizer.view;

NSLog(@"%@被点击了",label.text);
}
