Load Uiviewcontroller

Question

I have a Uiviewcontroller with the black Background where would be my main Uiviewcontroller (where is the menu and etc) and I do this:

CredenciaisViewController *obj = [self.storyboard instantiateViewControllerWithIdentifier:@"Credencial"];    
[_viewContainer addSubview:obj.view];
    _viewContainer.alpha = 1;

Credentialviewcontroller has the red background and I carry it in a Uiview that is in my main Uiviewcontroller, but when it loads inside the view it turns half white and the Uibuttons when they are in the white part do not work.

Why does this happen? And how do I solve?

Answer 1

You can’t add one UIViewController as subview other’s UIView. For that purpose, there is the Custom Container.

Then you can add through the method addChildViewController:childController in his UIContainerView and not UIView as in your example.

In the Builder interface you can locate him, so:

Dynamically, do something like this in the action of your UIButton:

- (IBAction)mostrarCredenciais:(id)sender {
    CredenciaisViewController *credenciaisView = [self.storyboard instantiateViewControllerWithIdentifier:@"Credencial"];

    [self addChildViewController:credenciaisView];
    [credenciaisView didMoveToParentViewController:self];
    credenciaisView.view.frame = self.containerView.bounds;
    [self.containerView addSubview:credenciaisView.view];
}

With this you don’t need to do so the connection on storyboard of the container with the UIViewController. Just turn on the IBOutlet (which is a UIView normal), which in my example is the containerView.
