How can you change value of animation while it's animating?

    I'm animating a UIView to a new Y location by changing the frame like this:

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:duration];
    [UIView setAnimationDelegate:self];
    mview.frame = newFrame;
    [UIView commitAnimations];

    Let's say newFrame currently has origin.y = 100. Now, while it's animating I need to change that to 200. Is there anyway to update the current animation or do I have to cancel the first one and start a new animation? I did try that, but there's a noticeable pause where the first animation stop and the new one starts.
