2）源码分享

- (UILabel *)targetLabelWithTitle:(NSString *)title{

       UILabel *label  = [[UILabel alloc]init];
       label.frame     = CGRectMake(0,self.view.frame.size.height /2, self.view.frame.size.width, 100);

       label.textColor = [UIColor orangeColor];
       label.textAlignment = NSTextAlignmentCenter;
       label.font          = [UIFont boldSystemFontOfSize:30.0f];

       NSRange startRange = [title rangeOfString:@"("];
       NSRange endRange   = [title rangeOfString:@")"];
       NSRange range      = NSMakeRange(startRange.location + startRange.length,endRange.location - (startRange.location + startRange.length));
       NSString *beforeString   = [title substringToIndex:startRange.location];
       NSString *resultString   = [title substringWithRange:range];

       //重置去掉"()"后的title
       NSString *handleString   = [NSString stringWithFormat:@"%@%@",beforeString,resultString];

       NSMutableAttributedString *attributedString = [[NSMutableAttributedString alloc] initWithString:handleString];
       NSRange resultRange = NSMakeRange([[attributedString string] rangeOfString:resultString].location, [[attributedString string] rangeOfString:resultString].length);
       //需要的特殊颜色
       [attributedString addAttribute:NSForegroundColorAttributeName value:[UIColor redColor] range:resultRange];
       //设置属性字符串
       label.attributedText = attributedString;

       return label;
}

3）使用方法

• ① 在你需要的地方创建Label；

• ② 传入带括号的（字符串）

• ③ 括号内的文字就是需要改变的目标颜色

  UILabel *l  = [self targetLabelWithTitle:@"啊哈哈哈(想不到吧)"];
  [self.view addSubview:l];
