1. convertGB_BIG

需要添加 big5.txt 和 gb.txt 文件

1. convertGB_BIG.h ```objective-c // // convertGB_BIG.h // myTest // // Created by sffofn on 11-8-17. // Copyright 2011 keke.com. All rights reserved. //

import

@interface convertGB_BIG : NSObject { NSString _string_GB; NSString _string_BIG5; }

@property(nonatomic, retain) NSString string_GB; @property(nonatomic, retain) NSString string_BIG5;

-(NSString)gbToBig5:(NSString)srcString; -(NSString)big5ToGb:(NSString)srcString;

@end
