xcode how to wait until json data parsing?

Question

I'm getting app info from the app store using json url.

I have to parse this file before showing the info in a uitableview.

How can I do that?

I mean waiting until all json wil be parsed and stored in an nsarray.

Any help will be really appreciated.

Lets suppose you begin all the good stuff in viewDidLoad . All you need to do is call the method where you get, parse, and store your data, then just reload the table view afterwards. Like this:

-(void)viewDidLoad {
    //this is your method where you parse data and put in your array
    [self parseData];

    //this reloads the table view, assuming you have your data source set up
    [tableView reloadData];
}
