Hi!
I´m running this code to scale and move an image in animation. It works perfectly the first run, but the next time I run this code the image does not animate.
I´ve put NSLog statements before and after the transforms to see if the image is affected. See the results below the code

Code:
-(void)animateShowImage:(UIButton *)button
{
     //set the starting animate position
     CGRect frameRect = imageView.frame;
     
     frameRect.size.width = button.frame.size.width;
     frameRect.size.height = button.frame.size.height;
     frameRect.origin = button.frame.origin;
     imageView.frame = frameRect;
     
     
     NSLog(@"imageview width : %f", imageView.frame.size.width);
     NSLog(@"imageview height : %f", imageView.frame.size.height);
     NSLog(@"imageview x : %f", imageView.frame.origin.x);
     NSLog(@"imageview y : %f", imageView.frame.origin.y);
     
     [UIView beginAnimations:nil context:NULL];
     [UIView setAnimationDuration:1.2];
     
     CGAffineTransform move = CGAffineTransformMakeTranslation(30, 20);
     CGAffineTransform scale = CGAffineTransformMakeScale(3,3);
     
     CGAffineTransform finalTransform = CGAffineTransformConcat(move, scale);
     imageView.transform = finalTransform;
     
     [UIView commitAnimations]; 
     
     NSLog(@"imageview width : %f", imageView.frame.size.width);
     NSLog(@"imageview height : %f", imageView.frame.size.height);
     NSLog(@"imageview x : %f", imageView.frame.origin.x);
     NSLog(@"imageview y : %f", imageView.frame.origin.y);
}

NSLog first run:

I can´t figure out what I´m doing wrong. Any help is apprechiated!
