How to replace the button positions by dragging one button on to another button in iphone sdk

Question

I am having two UIButtons(button1 and button2) of two different frames, the thing is I want to drag the button2 on to the button1 so that the button2 is repositioned to button1 position, and button2 should occupy button1 position.

Guy's I need ur help and ideas how can I do with it.

Thanks to all, Monish

Answer 1

CGRect rect = btn.frame;
btn.frame = btn2.frame;
btn2.frame = rect;

If you want to animate this, start with reading this

Is it what you are asking for?

Answer 2

You need to change the button's x-axis in frame and use animations to show it as its moving (if you want) accordingly.

[buttonOutletName setFrame:CGRectMake(old_xCoordinate, yCoordinate, width, height)];

[UIView beginAnimations:nil context:NULL];  
[UIView setAnimationDuration: 1.0];
[buttonOutletName setFrame:CGRectMake(new_xCoordinate, yCoordinate, width, height)];
[UIView commitAnimations];
