【iOS开发】emoji表情的输入思路

1.自定义一个表情包类继承NSTextAttachment

 1 #import <UIKit/UIKit.h>
 2 
 3 /** 表情包的自定义类*/
 4 @interface EmojiTextAttach : NSTextAttachment
 5 
 6 @property (nonatomic,assign) NSRange  range;
 7 
 8 /** 绑定NSTextAttachment所表示的表情和与其对应的标志*/
 9 @property (nonatomic, copy) NSString *emojiTag;
10 
11 /** 表情名称*/
12 @property (nonatomic, copy) NSString *emojiName;
13 
14 
15 @end
