Custom Push and Pop Animations iOS 7 and 8

I am using this code for a custom model transition -

For Push

CATransition *transition = [CATransition animation];
transition.type          = kCATransitionPush;
transition.duration      = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.subtype       = kCATransitionFromTop;

[view.layer addAnimation:transition forKey:nil];

For Pop

CATransition *transition = [CATransition animation];
transition.type          = kCATransitionPush;
transition.duration      = 0.3;
transition.timingFunction = [CAMediaTimingFunction functionWithName:kCAMediaTimingFunctionEaseInEaseOut];
transition.subtype       = kCATransitionFromBottom;

[view.layer addAnimation:transition forKey:nil];

view is self.navigationController.view

how can i change this to make Zoom and Zoom animations. any suggestions.

You can use this code:

Enlarge animation:

self.yourComponent.transform = CGAffineTransformMakeScale(1, 1);
[UIView beginAnimations:@"zoomIn" context:nil];
[UIView setAnimationDuration:1.0]; // Time in seconds
self.yourComponent.transform = CGAffineTransformMakeScale(1.2, 1.2); // 20% bigger


Decrease animation:

self.yourComponent.transform = CGAffineTransformMakeScale(1.2, 1.2);
[UIView beginAnimations:@"zoomOut" context:nil];
[UIView setAnimationDuration:1.0]; // Time in seconds
self.yourComponent.transform = CGAffineTransformMakeScale(1, 1);

self.yourComponent

It can be UIView

, UIImageView

, UIButton

or any other component.
