title: How to change the frame a UIButton after it has been created?
body: <p>In my ViewDidLoad I create a UIButton programmatically and assign it the tag 1. </p>
  
  <p>Later on I use the code:
         UIButton* otherButton = [self.view viewWithTag:1];
  Now this button works perfectly with code, changing the frame etc!
  Except I get the warning: 
  Incompatible pointer types assigning to 'UIButton *' from 'UIView *'</p>
  
  <p>Is there a better way to find the button, or should I just ignore the error? </p>
