ios NSMutableAttributedString 实现富文本（不同颜色字体、下划线等）

效果图：

- (void)setLabText:(NSString *)text
{NSMutableAttributedString *attributedStr = [[NSMutableAttributedString alloc] initWithString:text];[attributedStr addAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:16],NSForegroundColorAttributeName:COLOR_252525} range:NSMakeRange(0, 4)];[attributedStr addAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:18],NSForegroundColorAttributeName:COLOR_0093FF} range:NSMakeRange(4, text.length-5)];[attributedStr addAttributes:@{NSFontAttributeName:[UIFont systemFontOfSize:12],NSForegroundColorAttributeName:COLOR_999999} range:NSMakeRange(text.length-2, 2)];_Lab.attributedText = attributedStr;
}
