iOS - NSURLSessionTask unzip file downloaded - ios

Question

I have files download at didFinishDownloadingToURL: and I want to unzip it. My current code looks like this:
- (void)URLSession:(NSURLSession *)session downloadTask:(NSURLSessionDownloadTask *)downloadTask didFinishDownloadingToURL:(NSURL *)location
{
for(NSMutableDictionary *downloadInfo in downloadingArray)
{
if([[downloadInfo objectForKey:kMZDownloadKeyTask] isEqual:downloadTask])
{
if (location)
{
NSString *srcPath = location.absoluteString;
NSString *fullPathDst = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
//unzip
ZipArchive *zipArchive = [[ZipArchive alloc] init];
[zipArchive UnzipOpenFile:srcPath Password:#"pasword"];
[zipArchive UnzipFileTo:fullPathDst overWrite:YES];
[zipArchive UnzipCloseFile];
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *files = [fileManager contentsOfDirectoryAtPath:fullPathDst error:&error];
NSLog(#"files: %#", files);
}
break;
}
}
}
the files array is empty. What am I doing wrong?

Answer 1

You shouldn't use absoluteString, as that includes a scheme (e.g. file://). Use path method, instead.

Answer 2

You have not written the file name and file type :-
NSString *filepath = [[NSBundle mainBundle] pathForResource:#"ZipFileName" ofType:#"zip"];

Answer 3

The unzipping would create a folder in documents directory which would contain the files. Please check that
NSString *zipPath = [[NSBundle mainBundle] pathForResource:zipFileName ofType:#"zip"];
NSString *destinationPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
Get zip file from documents directory:-
NSString *filename = #"MyZipFile.zip";
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString * zipPath = [documentsDirectory stringByAppendingPathComponent:filename];
NSString *destinationPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
[SSZipArchive unzipFileAtPath:zipPath toDestination:destinationPath];
