 8          NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];//创建不带密码zip压缩包
 9          //创建zip压缩包
10          [zip CreateZipFile2:path];

13      　　 //添加到zip压缩包的文件

 5          //Caches路径
 6          NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
 7      　　//解压目标路径
 8          NSString *savePath =[cachesPath stringByAppendingPathComponent:@"ZipArchive"];
 9      　　//zip压缩包的路径
10          NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];
11          //解压不带密码压缩包
12          [zip UnzipOpenFile:path];
13          //解压带密码压缩包
14          //[zip UnzipOpenFile:path Password:@"ZipArchive.zip"];
15          //解压
16          [zip UnzipFileTo:savePath overWrite:YES];
17          //关闭解压
18          BOOL success = [zip UnzipCloseFile];
