NSMutableAttributedString 图文混排
首先你先搞一个图片：NSTextAttachment * textImage = [NSTextAttachment new];

textImage.image = [UIImage imageNamed:<#name#>];

textImage.bounds = CGRectMake(0, 0, 40, 30);



NSMutableAttributedString * attrstring =  [NSAttributedString appendAttributedString: [NSAttributedString attributedStringWithAttachment:textImage]];
