Question

I am trying to remove two viewcontrollers (that have been added on top of each other) with one method. I have made the views in interfacebuilder. they all have their own .h and .m files to go with it.

Scenario I am in:

I have a main menu which has the view2 header file imported.
In a method I add the second view on top of the superview like so

view2ViewController * view2 = [[view2ViewController alloc] initWithNibName:@"view2ViewController" bundle:nil];
[self.view addSubview:view2.view];

then in view 2 I have added the view 3 header file so i can add view 3 as a subview ontop of view2. i have another method which is connected again to interface builder to a UIButton so upon button press a method gets called in view2 which adds view 3 on top in exactly the same way like so:

view3ViewController * view3 = [[view3ViewController alloc] initWithNibName:@"view3ViewController" bundle:nil];
[self.view addSubview:view3.view];

What im trying to solve:
I have a button in view 3 which should remove view 3…. and then it should also remove view 2 aswell so the main screen is visible.

How can this be achieved?

What I have so far:

[self.view removeFromSuperview];

This however only removes View 3… but leaves view 2 in place.

What needs to be modified so that i can remove view 2 as well??

Any help is appreciated.

Answer 1

I would normally do this as adding view2 and view3 as subviews of the main view. Then when the button actions are triggered, the adding and removing of subviews will be executed by the main view’s view controller.

For a quick hack, I think you can try this in your button handler.

[self.view removeFromSuperview];
[self.view.superview removeFromSuperview];

Though I’m not sure if you should be doing it. 😛
