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 >> Code: [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.
