View not animating

I'm using this method to try to move my view up but without success, this is the code in my MainViewController implementation file :

[UIView beginAnimations:nil context:NULL];
[UIView setAnimationDuration:0.5];

CGRect rect = self.view.frame;
if (movedUp)
{
    NSLog(@"should move Up");
    rect.origin.y -= 50;
    rect.size.height += 300;
}
self.view.frame = rect ;

[UIView commitAnimations];

It is not erroring out and it's printing out "should move Up" so I know that the method is executed properly .

This is the IB hierarchy ( I`m trying to move the highlighted View) :

alt text

Any help would be greatly appreciated, I`m running out of ideas ..

Ok, Editing here I've isolated the problem to be something else, I'm using this code now :

[UIView beginAnimations:nil context:nil];
[UIView setAnimationDuration:.5];

self.containerView.frame = CGRectMake(0, 0, 250, 50);

[UIView commitAnimations];

and if I injecting this code in "- (void)viewDidLoad" it's working fine .

but if I use the same code in a different function in the same ViewController implementation file , it's not working :

- (void)setViewMovedUp:(BOOL)movedUp {


        NSLog(@"test movedUp");
        [UIView beginAnimations:nil context:nil];
        [UIView setAnimationDuration:.5];

        self.containerView.frame = CGRectMake(0, 0, 250, 50);

        [UIView commitAnimations];



}

BUT it's still printing out "test moved up" so the code is executed, just the view not animating .

use 

[self.view setFrame:rect];

instead of

self.view.frame = rect ;

I think the animation will not be used for self.view.

go through this link using the tableview as horizontal scroll and animating the views and also animating the text like marquee check in the method -(void)handleSwipeGesture:(UISwipeGestureRecognizer *) sender

Try moving another view - not the main one.
Maybe there is a problem moving the main view.

If it works then add one more view to your views hierarchy that will contain all the others and connect it to a IBOutlet.

If it doesn't work then comment me and we'll try to figure it out...
