Question

I have a navigation controller and a button located on the right of the navigation bar that is called toggle. When ever I press the button I basically want to toggle between a table view and a map view. How can I do this?

Can this be done by pushing and popping from the navigation stack back and forth?

Answer 1

Ok… what you want can be done using navigationControllers and such.

You just need to make a method in both viewControllers, and in the viewDidLoad of each put this:

[self.navigationItem setRightBarButtonItem:[[[UIBarButtonItem alloc] initWithTitle:@"Toggle" style:UIBarButtonItemStylePlain target:self action:@selector(toggleView:)] autorelease]];

then you want this method in the first view you get to (lets say its the list view):

-(void)toggleView:(id)selector {
    MapViewController *mapViewController = [[MapViewController alloc] initWithNibName:nil bundle:nil];
    [self.navigationController pushViewController:mapViewController animated:NO]; // this pushes a view onto the stack
    /* or you could use this:
    [self presentModalViewController:mapViewController animated:YES];
    // which slides the view up over the current view */
    [mapViewController release];
}

then in the mapview:

- (void)toggleView:(id)selector {
        [self.navigationController popViewControllerAnimated:YES]; // this pops back a view
        /* or you went for the second option above:
        [self dismissModalViewControllerAnimated:YES];
        // which slides the view back down. */
}
