单击UIButton时更改其位置

Question

I'm putting together an app that uses a keyboard (like the native iPhone one) that has symbols on the keys. My question is how to I change the location of a button when it is clicked (as the UIControlStateHighlighted images is bigger than the regular state).

Thanks for any help/pointers.

Answer 1

All UIView instances have a frame, bounds, center, and transform properties. You can use any or all of these to manipulate your button. Changing the center may be all you need to do.

Answer 2

Try this:

[yourView setFrame:CGRectMake(yourHorizontalPosition,yourVerticalPosition,[yourView.frame.size width],[yourView.frame.size height])];

Does that work for you?
