label,label在开发中有时候能要了老命，一怒之下就写了这个Label,Label ,Label 不废话，直接上图看效果,
下面直接上demo
NSString* str1 = @"隔壁老王";
NSString* str2 = @"回复";
NSString* str3 = @"隔壁老李";
NSString* str4 = @"该好好练练腰了，腰好才是真的好，腰好才是真的好，腰好才是真的好";
NSMutableAttributedString* attString = [[NSMutableAttributedString alloc]initWithString:[NSString stringWithFormat:@"%@%@%@%@",str1,str2,str3,str4]];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor purpleColor] range:NSMakeRange(0,str1.length)];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:NSMakeRange(str1.length,str2.length)];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor orangeColor] range:NSMakeRange(str1.length+str2.length,str3.length)];
[attString addAttribute:NSForegroundColorAttributeName value:[UIColor blackColor] range:NSMakeRange(str1.length+str2.length+str3.length,str4.length)];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"PingFangSC-Regular" size:10.0] range:NSMakeRange(0, str1.length)];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Helvetica-Bold" size:12.0] range:NSMakeRange(str1.length,str2.length)];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"PingFangSC-Regular" size:10.0] range:NSMakeRange(str1.length+str2.length,str3.length)];
[attString addAttribute:NSFontAttributeName value:[UIFont fontWithName:@"Helvetica-Bold" size:12.0] range:NSMakeRange(str1.length+str2.length+str3.length,str4.length)];
UILabel* labelAttr = [[UILabel alloc]init];
labelAttr.backgroundColor = [UIColor lightGrayColor];
labelAttr.attributedText = attString;
labelAttr.numberOfLines = 0;
labelAttr.lineBreakMode = NSLineBreakByTruncatingTail;
CGSize max = CGSizeMake(300, 99999);
CGSize ex = [labelAttr sizeThatFits:max];
labelAttr.frame = CGRectMake(50, 100, ex.width, ex.height);
[self.view addSubview:labelAttr];
你随便想怎么改就怎么改，就这么简单，粗暴
