把文件压缩成zip包的代码

这段代码由 CocoaChina 会员“garnett2183”分享，适用于 Mac 应用中添加文件压缩功能。

+(BOOL) archiveFile:(NSString*)srcfile destZipFile:(NSString*)zipfile {    
    NSTask * zipTask = [[NSTask alloc] init];
    [zipTask setLaunchPath:@"/usr/bin/ditto"];
    [zipTask setArguments:
     [NSArray arrayWithObjects:@"-c", @"-k", @"-X", @"--rsrc", 
      srcfile, zipfile, nil]];

    [zipTask launch];
    [zipTask waitUntilExit];

    if ([zipTask terminationStatus] != 0){
        NSLog(@"can't zip file:%@", srcfile);
        return NO;
    }

    [zipTask release];
    
    return YES;
}
