Question

I would like to know how to access the downloaded content from my server in Newsstand app. I have successfully downloaded the zip file which has all the useful assets for my app in the Caches Directory by using the NKAssetDownload. I know we can unzip the folder using ZipArchive. But to do that I am unable to find a way to access the path of the downloaded zip file.

Currently the path is:

simulator -> Applications -> my_app_id -> Library -> Caches -> Newsstand -> (some folder with Hexadecimal name) -> magazine.zip

magazine.zip is my downloaded file. the problem is with this Hexadecimal folder name.

Now I need help with any bit of code which can unzip this file and use the image.png in the unzipped folder in my imageView.

This is the code I have used:

NKLibrary *library = [NKLibrary sharedLibrary];

NKIssue *firstIssue = [library issueWithName:@"First Issue"];
firstIssue = [library addIssueWithName:@"First Issue" date:[NSDate date]];
NSURLRequest *urlReq = [NSURLRequest requestWithURL:[NSURL URLWithString:@"location of my zip file"]];
NKAssetDownload *asset = [firstIssue addAssetWithRequest:urlReq];

[asset downloadWithDelegate:self];

Answer 1

the NKAssetDownload takes a delegate, just like NSURLConnection does.

You should implement the NSURLConnectionDownloadDelegate protocol and in the method - (void)connectionDidFinishDownloading:(NSURLConnection *)connection destinationURL:(NSURL *)destinationURL you get passed the url to the zip
