uilabel的不同的区域的内容的颜色不同

NSString *wenzi = [NSString stringWithFormat:@"亲，您还有%@次机会", model.LUCKYDEGREE];//model.LUCKYDEGREE是数字 NSMutableAttributedString *jihui = [[NSMutableAttributedString alloc] initWithString:wenzi]; NSRange orangeRange = NSMakeRange([[jihui string] rangeOfString:model.LUCKYDEGREE].location, [[jihui string] rangeOfString:model.LUCKYDEGREE].length); [jihui addAttribute:NSForegroundColorAttributeName value:self.color range:orangeRange]; [self.label1 setAttributedText:jihui];

label的内容中的数字是橘黄色的，其他的是默认的颜色
