How can I keep a UIButton in same location after changing the Image?

I have a UIButton that is able to change locations on the screen after it has been clicked. The user then clicks a different button to change the image of the button and I want it to stay in its new location. Currently with my code it is reverting back to the original position after changing the image. Here is the code:

First move the Button (newLocation is a location of a UIImageView):

movableButton.center = [newLocation center];

Then Change the button image by clicking a different button:

[movableButton setImage:[UIImage imageNamed: @"differentImage.png"] forState:UIControlStateNormal];

Ok now i got your question , what you can do is start a counter in 2nd button's action:

-(void)secondButtonClick
{
 static int counter = 1;
   if(counter %2  == 0) 
   {
     firstButton.center =cgpoint a;  // a gain some point where you wan't to place the center
    }
 if(counter %2 != 0)
    {
      [firstButton setBackgroundImage:[UIImage imageNamed:@"logout.png"] forState:UIControlStateNormal];
     }

counter ++;

}

you can modify if condition whether you want position changed before changing image..... Also uou can change the center alsolike this

a.x =a.x+10;
a.y =a.y +10;
myButton.center = a;

I dont understand why it moves. I just tested it, and it does move. I need to look into why it moves and will get back to you.

But this will fix the problem of it moving.

CGPoint currentLoc = self.imageButton.center;
[self.imageButton setImage:[UIImage imageNamed:@"face"] forState:UIControlStateNormal];
self.imageButton.center = currentLoc;

Try this

-(IBAction) movingButtonClicked
{
      [movingButton setFrame:CGRectMake(movingButton.frame.origin.x+10,movingButton.frame.origin.y+20,50,50)];
}

-(IBAction) changeImage
{
     [movingButton setImage:[UIImage imageNamed: @"differentImage.png"] forState:UIControlStateNormal];
}
