why my iOS app just goes to @synthesize, but not go to viewWillAppear and viewDidLoad further?

Question

My Map app has a " Select city " button to show worldCitiesList when clicked using the following code:

[self.navigationController presentModalViewController:self.worldCitiesListNavigationController animated:YES];

But now the place for the " Select city " button has to be replaced by another button.

the " Select city " button has to be relocated to another viewcontroller created from the MapViewController by the following code:

[self.navigationController presentModalViewController:self.tableViewNavigationController animated:YES];

The worldCitiesList can be showed from the tableViewNavigationController. But we want it is still showed from the MapViewController as before.

So in the button of backing to the MapViewController from the tableViewNavigationController, I use following code to first back to MapViewController, then to show the worldCityList:

- (void) backMapView:(id)sender
{
    [self.navigationController dismissModalViewControllerAnimated:YES];

    [self.navigationController presentModalViewController:self.worldCitiesListNavigationController animated:YES];
}

But my app just return to MapViewControler, but not show the worldCityList further.

In my WorldCitiesListController.m, my iOS app just goes to @synthesize, but not go to viewWillAppear and viewDidLoad further.

Please help. thanks in advance !!!
