IOS下利用ziparchive解压缩zip文件

http://www.zdoz.net

ziparchive是基于开源代码”MiniZip”的zip压缩与解压的Objective-C 的Class,使用起来非常的简单
方法：从http://code.google.com/p/ziparchive/ 上下载ZipArchive.zip，解压后将代码加入工程中，并且把libz.dylib库添加到工程中
使用方法：

1. 压缩:ZipArchive可以压缩多个文件,只需要把文件一一addFileToZip即可.

  

   

    

     

    
    

     

      ZipArchive* zip = [[ZipArchive alloc] init];
     
    
   

    

     

    
    

     

      NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
     
    
   

    

     

    
    

     

      NSString *documentpath = ([paths count] > 0) ? [paths objectAtIndex:0] : nil;
     
    
   

    

     

    
    

     

      NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ;
     
    
   

    

     

    
    

     
          
     
    
   

    

     

    
    

     

      NSString* image1 = [documentpath stringByAppendingString:@"/image1.jpg"] ;   
     
    
   

    

     

    
    

     

      NSString* image2 = [documentpath stringByAppendingString:@"/image2.jpg"] ;       
     
    
   

    

     

    
    

     
          
     
    
   

    

     

    
    

     

      BOOL ret = [zip CreateZipFile2:l_zipfile];
     
    
   

    

     

    
    

     

      ret = [zip addFileToZip:image1 newname:@"image1.jpg"];
     
    
   

    

     

    
    

     

      ret = [zip addFileToZip:image2 newname:@"image2.jpg"];
     
    
   

    

     

    
    

     

      if( ![zip CloseZipFile2] )

      NSString* l_zipfile = [documentpath stringByAppendingString:@"/test.zip"] ;
     
    
   

    

     

    
    

     

      NSString* unzipto = [documentpath stringByAppendingString:@"/test"] ;
