IOS UILabel用NSAttributedString来实

很多时候都想在UILabel实现图片文字共存的效果，用NSAttributedString与NSTextAttachment实现大家想要的效果。

代码如下：

UIlabel * lab = [[UIlabel alloc] init];
NSTextAttachment *attach = [[NSTextAttachment alloc] init];
attach.image = [UIImage imageNamed:@"ic_home_bluelion"];
NSAttributedString *collegeStr = [NSAttributedString attributedStringWithAttachment:attach];
lab.attributedText = collegeStr;

如下图红线框标注所示效果： ios_text.png
