iOS animate my CGpointMake

[jjgraz]

So I have an image moving across the screen.

I can use something like:

[self moveImage:aViewa duration:4.0 
			 curve:UIViewAnimationCurveLinear x: 20.0 y:00.0];

However, I would like to get image current location, and animate it to next position. So I have something like:

CGPoint oldPosition = aViewa.center;
	aViewa.center = CGPointMake(oldPosition.x - 20, oldPosition.y);

This does the job, but doesn't animate the move.....It just jumps to new location. How would I integrate the animation so it slides over as it did before?

Thank you very much.

As per the documentation for the center property you need to use beginAnimations:context: and commitAnimations.
