Question

I am having some issues with some animation stuff in an iPad application. I have four UIButtons that are on the screen when the app launches.

I basically want the app to load and the four buttons to animate into view one at a time from the top of the screen into place.

I have the following which kind of animates it but I am struggling with it.

-(void)viewWillAppear:(BOOL)animated
{
    CGPoint newLeftCenter = CGPointMake( 15.0f + myCocoButton.frame.size.width / 2.0f, myCocoButton.center.y);
    [UIView beginAnimations:nil context:nil]; 
    [UIView setAnimationDuration:4.0f];
    myCocoButton.center = newLeftCenter;
    [UIView commitAnimations];

}

The current code that I have does animate the button but not in the way I want. I can’t get my head around how to actually place it exactly where I want it.

I’ve written a blog post about this subject: http://www.roostersoftstudios.com/2011/07/01/iphone-dev-performing-sequential-uiview-animations/

and I have a sample project there.

You can just chain the animations where when one finishes it calls the function of the next animation. Can you be more specific about the exact issues you are having?
