iOS-属性字符串添加下划线、删除线

常用到的属性字符串

///定义属性字符串
NSMutableAttributedString *att  = [[NSMutableAttributedString alloc]initWithString:@""];
///删除线
[att addAttribute:NSStrikethroughStyleAttributeName value:@(NSUnderlineStyleSingle | NSUnderlineStyleSingle) range:NSMakeRange(0, 0)];
///字体大小
UIFont *font = [UIFont fontWithName:@"Helvetica-Bold" size:17.0];
[att addAttribute:NSFontAttributeName value:font range:NSMakeRange(0,0)];
///字体颜色
[att addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(0, 0)];
// 下划线
[att addAttribute:NSUnderlineStyleAttributeName value:[NSNumber numberWithInteger:NSUnderlineStyleSingle] range:NSMakeRange(0, 0)];

直接赋给label就可以了
