Question

How can I position a button on my view dynamically?

Answer 1

Ok, now we understand the question better…

You can place a button/UIComponent at runtime by settings its frame. This will place it at a given coordinate within the view containing the button.

myButton.frame = CGRectMake(newX, newY, myButton.frame.width, myButton.frame.height);

If you wish to do a linear style animation (no curves), look up CATransitions, see iPhone UIView Animation Best Practice. If you need to support pre-iOS4 devices, you can’t use CATransitions, and have to do it the old way using UIView animations.

To do more complex animations, you might have to mess around with timers, which can slightly juddery effects if you’re trying to do complicated animation paths.
