今天遇到了在label和button下方划线的问题，请教了百度

UILabel设置下划线:

UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(10, 100, 310, 50)];

label.backgroundColor = [UIColor redColor];

[label setLineBreakMode:NSLineBreakByWordWrapping];

label.numberOfLines =3;

[label setFont:[UIFont systemFontOfSize:14]];

NSMutableAttributedString*content = [[NSMutableAttributedStringalloc]initWithString:[NSStringstringWithFormat:@"博文地址:http://www.cnblogs.com/xiaofeixiang博客园-FlyElephant QQ群:228407086"]];

NSRangecontentRange = {0,[content length]};

[content addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInteger:NSUnderlineStyleSingle] range:contentRange];

label.attributedText = content;

[self.view addSubview:label];

UIButton设置下划线:

UIButton *button=[[UIButton alloc]initWithFrame:CGRectMake(10, 200, 80, 30)];

NSMutableAttributedString*title = [[NSMutableAttributedStringalloc] initWithString:@"FlyElephant"];

NSRangetitleRange = {0,[title length]};

[title addAttribute:NSUnderlineStyleAttributeNamevalue:[NSNumbernumberWithInteger:NSUnderlineStyleSingle] range:titleRange];

[button setAttributedTitle:title

forState:UIControlStateNormal];

[button setBackgroundColor:[UIColor redColor]];

[button.titleLabel setFont:[UIFont systemFontOfSize:14]];

[self.view addSubview:button];
