- 创建NSTextAttachment的对象,用来装在图片
- 将NSTextAttachment对象的image属性设置为想要使用的图片
- 设置NSTextAttachment对象bounds大小,也就是要显示的图片的大小
- 用[NSAttributedString attributedStringWithAttachment:attch]方法,将图片添加到富文本上
//创建富文本字符串
NSMutableAttributedString *mAString = [[NSMutableAttributedString alloc] initWithString:@"你好你好你好你好你好你好你你好你好你好你好你好你好你你好你好你好你好你好你好你"];
//创建图片
NSTextAttachment *attch = [[NSTextAttachment alloc] init];
attch.image = [UIImage imageNamed:@"ding"];
attch.bounds = CGRectMake(0, -2, 16, 16);
//将图片加入富文本
NSAttributedString *imgString = [NSAttributedString attributedStringWithAttachment:attch];
[mAString appendAttributedString:imgString];
_Alabel.attributedText = mAString;
