iOS How to animate when no reference to target view?

[Earl Grey]

Hi,

In my iOS5 app for iPhone, I have something like this

AppDelegate
ivar ViewController1
ivar ViewController2


ViewController1
ivar view1
ivar button1
IBAction animateToView


ViewController2
ivar view2


Now I want to animate from view1 from viewcontroller1 to view2 from viewcontroller2 by pushing a button in viewcontroller1.
Bu I do not have a reference to the view2 to the viewcontroller2 in viewcontroler1.

If I hook the button to an action/target and use block based animation in it
this one >>

    [UIView transitionFromView:<#(UIView *)#> 
                        toView:<#(UIView *)#> 
                      duration:<#(NSTimeInterval)#> 
                       options:<#(UIViewAnimationOptions)#> 
                    completion:<#^(BOOL finished)completion#>]

I am unable to fill in the toView: because of those missing references.

What would you recommend? IS it even good to solve thi by action target?

Thanks.

What I'd recommand, is make a category on your UIViewController, call it transitions, or whatever.
Code something in there to make your sliding in terms like

- (void) SlideToNextViewController:(UIViewController*)theViewController {
 //Animations go here. like, self.navigationController push Blah.
 }

Then call that in view 1.
Make a pointer to your second view you are transferring to, just give the pointer to your method from your category, and it should be fine.

transitionFromView:toView: is meant for animating view transitions within the same view controller. If you wish to animate to another view controller's view, perhaps consider presentModalViewController: in conjunction with modalTransitionStyle.
