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];
     }
