How would I go about adding a UIButton as an overlay to a mapView? This is what I have so far but it doesn't show up:

This is what I have:

UIButton *toMenu = [UIButton buttonWithType:UIButtonTypeRoundedRect]; toMenu.frame = CGRectMake(139, 539, 60, 60); [toMenu addTarget:self action:@selector(goToMenu:) forControlEvents:UIControlEventTouchUpOutside]; [toMenu setTitle:@"Arrow" forState:UIControlStateNormal]; [self.mapView addSubview:toMenu]; toMenu.hidden = false;

I also added the [self.mapView bringSubviewToFront:toMenu]; but when running the app nothing shows up :(..

Try adding the button to your view instead of your map, so instead of self.mapView addSubview try [self.view addSubview:toMenu]; or[self.view insertSubview:toMenu above: self.mapView];

Right so that worked.... Why? shouldn't the map be able to add subviews? Something I haven't tested is that perhaps the map did add it but the frame was created out of the view. I will move the parameters and see...

EDIT:

Checked but same issue, button doesn't show up! By using self.view it says that the 'view' is the view with the tap gesture... so I guess that would be the map in any case. Maybe theres a conflict there. I am quite new to this so still discovering stuff..

As developers you'll forever be learning. I had the same issue as you, but I wanted to add a table view to the map. I could be wrong but my guess is that the map view can only have one subview, the legal button.
