Use this demo for making multiple parallel request or multiple download. 
To use this demo import "MultipleDownload: .h & .m file into your project.
Implement following delegates method into your viewController

#pragma mark- download Delegate
- (void) didFinishDownload:(NSNumber*)idx {
    //want to load data, Use method "dataAtIndex" & convert data into required format extension like image, files etc
	NSLog(@"%d download: %@", [idx intValue], [downloads dataAsStringAtIndex: [idx intValue]]);
}

- (void) didFinishAllDownload {
	NSLog(@"Finished all download!");
	downloads =nil;
}

-(void)didFailDownloadWithError:(NSError*)error withRequest:(int)index
{
    NSLog(@"error is : %@",error.localizedDescription);
    // Fail url from mutable array at index "index"
    NSLog(@"Failed URL is : %@", [self.urlMutableArray objectAtIndex:index]);
}

In ViewDidLoad on your viewController.m file add following code

 self.urlMutableArray = [NSMutableArray arrayWithObjects:@"https://itunes.apple.com/search?term=jack+johnson",@"https://itunes.apple.com/search?term=jack+johnson&limit=25",@"https://itunes.apple.com/search?term=jack+johnson&entity=musicVideo",@"https://itunes.apple.com/search?term=jim+jones&country=ca",@"https://itunes.apple.com/search?term=yelp&country=us&entity=software",@"https://itunes.apple.com/lookup?amgArtistId=468749,5723",@"https://itunes.apple.com/lookup?amgArtistId=468749,5723&entity=song&limit=5&sort=recent", nil];
	self.downloads = [[MultipleDownload alloc] initWithUrls: self.urlMutableArray];
	self.downloads.delegate = self;
