change uiview frame from both sides

Question

Hello i want to make animation of a frame change. But i don't find nothing similar on the internet. I know how to animate the frame change, but the tricky part is that for example i have a square and i want it to shrink to the center. So how do i change frame to achieve that?

Do i have to change the frame width and height and also the origin of the frame, or maybe there is some simpler solution?

Any help or references on how to do it would be very appreciated! Thanks in advance!

If you need the View Shrinking Code, here it is.

    myView.transform=CGAffineTransformMakeScale(0.1, 0.1);
    [UIView beginAnimations:@"animationExpand" context:NULL];
    [UIView setAnimationDuration:0.4];
    myView.transform=CGAffineTransformMakeScale(1, 1);
    [UIView setAnimationDelegate:self];
    [UIView commitAnimations];

This is for making the View larger. If you want to make view shrink smaller then just replace the transform lines with each other.

Hope it helps! :)
