Pushing a View on a Different View with Result from Another View

I am creating a simple program where there is a main view which has a segmented control and a logo and some blank space. When the user clicks a segment of the Segmented Control, a view comes up just below the Segmented Control which has 6 buttons that leads user to different views.

I want that the view that appears right after the user clicks the button should not appear on the view where the buttons are (which it will if I use that "addSubView" option). Instead, I want the view to appear on the whole screen which means I want the resultant view (after clicking the button) to appear on the main view.

Thanks in Advance.

What your asking is: Is there a way that the subview can tell my mainView to add a new view. This can be done by delegation, singletons or notifications. I would suggest using a simple notification:

// This is your observer listening for the notification named @"LaunchViewOne"
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(LaunchViewOne) name:@"LaunchViewOne" object:nil];

// This is supplying the notification
[[NSNotificationCenter defaultCenter] postNotificationName:@"LaunchViewOne" object:nil];

So when your button is pressed use postNotification.

Take a look at UINavigationController. When the user click on one of the six buttons, you can use the pushViewController:animated: to navigate to the new view. By default, this will also give you a navigation bar at the top of the screen allow the user to go back. If you don't want that, you can turn that off though.

You can create property for all the controls that you need to access outside of its own class. Then you can access it as below:

Class c = [[Class alloc] init];
someValue = c.mypropery;

You can still use addSubView:, just that you don't want to do [viewWhereYouHaveButtons addSubView:someView], but [yourMainView addSubView:someView].

i don't understand your question, but you can use a lot of methods to manage views hierarchy

– addSubview:
– bringSubviewToFront:
– sendSubviewToBack:
– removeFromSuperview
– insertSubview:atIndex:
– insertSubview:aboveSubview:
– insertSubview:belowSubview:
– exchangeSubviewAtIndex:withSubviewAtIndex:
