压缩和解压缩(I)

ZipArchive

压缩方法

 -(void)zipArchiveWithFiles
     {
          //创建解压缩对象
          ZipArchive *zip = [[ZipArchive alloc]init];
          //Caches路径
          NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
          //zip压缩包保存路径
          NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];//创建不带密码zip压缩包
          //创建zip压缩包
          [zip CreateZipFile2:path];
          //创建带密码zip压缩包
          //[zip CreateZipFile2:path Password:@"ZipArchive.zip"];
      　　 //添加到zip压缩包的文件
          [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-700-568h@2x.png" newname:@"1.png"];
          [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-700@2x.png" newname:@"2.png"];
          [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-800-667h@2x.png" newname:@"3.png"];
          [zip addFileToZip:@"/Users/apple/Desktop/demo/LaunchImage-2-800-Landscape-736h@3x.png" newname:@"4.png"];
          //关闭压缩
          BOOL success = [zip CloseZipFile2];
      }

解压缩方法

 -(void)uZipArchive
     {
          //创建解压缩对象
          ZipArchive *zip = [[ZipArchive alloc]init];
          //Caches路径
          NSString *cachesPath = [NSSearchPathForDirectoriesInDomains(NSCachesDirectory, NSUserDomainMask, YES)lastObject];
      　　//解压目标路径
          NSString *savePath =[cachesPath stringByAppendingPathComponent:@"ZipArchive"];
      　　//zip压缩包的路径
          NSString *path = [cachesPath stringByAppendingPathComponent:@"ZipArchive.zip"];
          //解压不带密码压缩包
          [zip UnzipOpenFile:path];
          //解压带密码压缩包
          //[zip UnzipOpenFile:path Password:@"ZipArchive.zip"];
          //解压
          [zip UnzipFileTo:savePath overWrite:YES];
          //关闭解压
          BOOL success = [zip UnzipCloseFile];
      }
