iOS通信錄聯繫人列表較完整(中文排序)

代碼已上傳GitHub https://github.com/6357/YUChineseSorting.git

參考http://www.cnblogs.com/syxchina/archive/2012/10/11/2720257.html

1、須要導入頭文件pinyin.h這裏有下載地址http://download.csdn.net/detail/u013873967/6991579

這是我寫的完整代碼，歡迎你們學習交流，幫我改進。http://download.csdn.net/detail/u013873967/6992825

2、ChineseString.h

#import <Foundation/Foundation.h>
#import "pinyin.h"

@interface ChineseString : NSObject
@property(strong,nonatomic)NSString *string;
@property(strong,nonatomic)NSString *pinYin;

//-----  返回tableview右方indexArray
+(NSMutableArray*)IndexArray:(NSArray*)stringArr;

//-----  返回聯繫人
+(NSMutableArray*)LetterSortArray:(NSArray*)stringArr;

///----------------------
//返回一組字母排序數組(中英混排)
+(NSMutableArray*)SortArray:(NSArray*)stringArr;

@end
