Question

My app have a navigation bar on the top, and a tab bar on botton, over a mapview. I need a way to filter some pins of the mapview. So, i`m trying to add a bar or something like that, under the navigation bar.

This bar will have 2 text views and a button to perform the filtering job.
I need this bar to be retractile by pressing a button on my navigation bar.

If I run the project that way i get this:

The bar is floating in the wrong place. =s

I`m making it right? Or can I make it in another ‘best’ way?

Answer 1

You have to have an IBOutlet to the toolbar in your controller, and once the view is loaded, e.g. viewDidLoad, adjust its coordination, i.e. x and y to hide it.
Then, you can add a UIBarButtonItem that when triggered, it calls a toggle method to show or hide the toolbar, e.g.

- (IBAction)toggleToolbar {
 if (toolbar.isInView)
    [self hideToolbar];
 else
    [self showToolbar];
}

- (void) hideToolbar {
// implementation to hide the toolbar
}

- (void) showToolbar {
// implementation to show the toolbar
}
