iOS- 本地文本容错搜索引擎2-->如何实现英文（英文首字母，汉语拼音）对中文的搜索?

//判断字符串是否是中文
if ([ChineseInclude isIncludeChineseInString:@“百度"])
//然后将中文转换成拼音
NSString *pybody = [PinYinForObjc chineseConvertToPinYin:@"百度"];
//同时将中文转换成拼音首字母
NSString *pyheader = [PinYinForObjc chineseConvertToPinYinHead:@“百度”];

.

同时将拼音和拼音首字母加入关联
for (MenuItemObject *objmenu in allmenus) {
             //检测是否是有中文       
            if ([ChineseInclude isIncludeChineseInString:objmenu.displayname]) {
            //转换为拼音，和拼音首字母    
                NSString *pybody = [PinYinForObjc chineseConvertToPinYin:objmenu.displayname];
                NSString *pyheader = [PinYinForObjc chineseConvertToPinYinHead:objmenu.displayname];
            //将其索引关联上本地搜索引擎
                [[PermissiveResearchDatabase sharedDatabase] addRetainedObjet:objmenu forKey:pybody];
                [[PermissiveResearchDatabase sharedDatabase] addRetainedObjet:objmenu forKey:pyheader];
               
            }
            [[PermissiveResearchDatabase sharedDatabase] addRetainedObjet:objmenu forKey:objmenu.displayname];
}
