Image transition problem

Hey guys, how can make an image transition with two images. I need to transition the bucket image from scale 1.0, position of 160,100(x,y) to scale 0.5, position of 160,250(x,y) at duration of 2 and the reference point is at center of the bucket.png image.

here is the image :

See if you can use this snippet to do what you want. To handle the scaling you need a CGAffineTransform. Then in the completion block you can swap to the 1x image and apply the identity transform.

       imageView.transform = CGAffineTransformMakeScale(0.5, 0.5);
       imageView.frame = newFrame;
   completion:^(BOOL finished) {
       imageView.image = newImage;
       imageView.transform = CGAffineTransformIdentity;

Could you please give me full code because i want to study full code and as you know i'm novice in iOS development. Sometimes simple things for you is hard for me. Marshall Huss
