Create a Method ?

I wan to parse JSON from 2 URLs from youtube and load all the results on one UITableView.

Do i have to use JSON Serialization twice or is it possible to create a method ?

How do i create a Method? Here my code for getting JSON from one URL:

    - (void)viewDidLoad
{
    [super viewDidLoad];


    NSString *urlAsString = @"http://gdata.youtube.com/feeds/api/playlists/PL0l3xlkh7UnvLdr0Zz3XZZuP2tENy_qaP?v=2&alt=jsonc&max-results=50";


    NSURL *url = [NSURL URLWithString:urlAsString];

    NSURLRequest *request = [NSURLRequest requestWithURL:url];

   // This will initiate the request and parse the data using apples JSONSerialization

       AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {



       self.videoMetaData = [JSON valueForKeyPath:@"data.items.video"];

       // This will have all the sq and hq thumbnails

       self.allThumbnails = [JSON valueForKeyPath:@"data.items.video.thumbnail"];

       // Grab the video ID

       self.videoID = [JSON valueForKeyPath:@"data.items.video.videoID"];


       [self.tableView reloadData]; // Must Reload

      // NSLog(@" video Meta Data %@", self.videoMetaData);





    } failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
        NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
    }];

    [operation start];

I tried this but i could not make it work:

-(void)getJSONfromURL:(NSURL *)url {

NSURLRequest *request = [NSURLRequest requestWithURL:url];
// setup AFNetworking stuff
AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON) {
    // call delegate or processing method on success
    myJSON = (NSMutableArray *)JSON;

} failure:^(NSURLRequest *request, NSHTTPURLResponse *response, NSError *error, id JSON) {
    NSLog(@"Request Failed with Error: %@, %@", error, error.userInfo);
}];


[operation start];

}

@tauseef that should work except that you probably want to append to your mutable array instead of writing over it. 

   [myJSON addObjectsFromArray:(NSArray *)JSON];
