How to unzip a .zip file on iOS? [duplicate]

Answer 1

There is a great 3rd party tool for zipping/unzipping files for iPhone

https://github.com/soffes/ssziparchive

Very simple to use. Hope that helps!!

Edit:

Quick method I created which takes url, downloads the zip and unzips it

-(void)downloadAndUnzip : (NSString *)sURL_p : (NSString *)sFolderName_p
{
    dispatch_queue_t q = dispatch_get_global_queue(0, 0);
    dispatch_queue_t main = dispatch_get_main_queue();
    dispatch_async(q, ^{
        //Path info
        NSURL *url = [NSURL URLWithString:sURL_p];
        NSData *data = [NSData  dataWithContentsOfURL:url];
        NSString *fileName = [[url path] lastPathComponent];
        NSString *filePath = [NSTemporaryDirectory() stringByAppendingPathComponent:fileName];
        [data writeToFile:filePath atomically:YES];
        dispatch_async(main, ^


                 {
                       //Write To
                       NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
                       NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
                       NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:sFolderName_p];

                       [SSZipArchive unzipFileAtPath:filePath toDestination:dataPath];

                   });
});

}
