CkoZip *zip = [[CkoZip alloc] init]; success = [zip OpenZip: @"my_files.zip"]; if (success == NO) { NSLog(@"%@",zip.LastErrorText); return; } NSString *unzipDir = @"/temp/unzipDir"; // Get the number of files and directories in the .zip int n = [zip.NumEntries intValue]; CkoZipEntry *entry = [[CkoZipEntry alloc] init]; int i = 0; while (i < n) { [zip EntryAt: [NSNumber numberWithInt: i] entry: entry]; if (entry.IsDirectory == NO) { // (the filename may include a path) NSLog(@"%@",entry.FileName); // Your application may choose to unzip this entry // based on the filename. // If the entry should be unzipped, then call Extract(unzipDir) success = [entry Extract: unzipDir]; if (success == NO) { NSLog(@"%@",entry.LastErrorText); return; } } i = i + 1; } |
