您可以使用SSZipArchive来处理zip文件。

下面的行将解压缩并将图像分配给NSArray

   // Unzipping
NSString *zipPath = @"path_to_your_zip_file";
NSString *destinationPath = @"path_to_the_folder_where_you_want_it_unzipped";
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];

// Zipping
NSString *zippedPath = @"path_where_you_want_the_file_created";
NSArray *inputPaths = [NSArray arrayWithObjects:
                       [[NSBundle mainBundle] pathForResource:@"photo1" ofType:@"jpg"],
                       [[NSBundle mainBundle] pathForResource:@"photo2" ofType:@"jpg"]
                       nil];
[SSZipArchive createZipFileAtPath:zippedPath withFilesAtPaths:inputPaths];

要删除文件：

- (void)deleteFile:(NSString *)fileName
{
  NSFileManager *fileManager = [NSFileManager defaultManager];
  NSString *documentsPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

  NSString *filePath = [documentsPath stringByAppendingPathComponent:fileName];
  NSError *error;
  BOOL success = [fileManager removeItemAtPath:filePath error:&error];
  if (success) {
      UIAlertView *removeSuccessFulAlert=[[UIAlertView alloc]initWithTitle:@"Congratulation:" message:@"Successfully removed" delegate:self cancelButtonTitle:@"Close" otherButtonTitles:nil];
      [removeSuccessFulAlert show];
  }
  else
  {
      NSLog(@"Could not delete file -:%@ ",[error localizedDescription]);
  }
}
