Lazy loading of a uitableView?

I have a Navigation Controller. When user taps a button a new UIViewCon开发者_C百科troller is pushed into the stack. This new view retrieves some information from a google api and shows it in a tableview. My problem is that the tableview isn't showing. I retrieve the info once the view has loaded so I can show an activity indicator.

- (void)viewDidAppear:(BOOL)animated
{
    centersNames = [[NSMutableArray alloc] init];
    placesFromXml = [[NSMutableArray alloc] init];
    vicinity = [[NSMutableArray alloc] init];
    [self ParseXML_of_Google_PlacesAPI];
    [self.tableview reloadData]; //Doesn't work
    [super viewDidAppear:animated];
}

How can I make the tableview appear after loading the info?

Thanks in advance and sorry for my English.

Finally I got the solution. The problem was the navigation controller wasn't calling viewWillAppear, etc. Solution found here:
