How to animate when no reference to target view?

Web Dev · January 2012

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.

Why not use a UINavigationController? Just allocate view controller 2 in code.

You need to create a instance of ViewController2. And then pass that view2 to the transition. Check this out -

ViewController2 *twoVC = [ViewController2 alloc] initWithNibName:@"ViewController2" bundle:[NSBundle mainBundle]];
[UIView transitionFromView:view1
toView:twoVC.view2
duration:0.5
options:UIViewAnimationOptionTransitionFlipFromLeft
completion:^(BOOL finished){
/* do something on animation completion */
}];
}

Howdy, Stranger!
