Can't you just change the frame within a UIView animation block. It looks like that CABasicAnimation is not required in this case.

[UIView beginAnimations:@"resize_animation" context:NULL];

// 0.1 is really short to understand what is going wrong
[UIView setAnimationDuration:2]; 

btnHead.frame = newFrame;

[UIView commitAnimations];
