Add Option to Configure Animation Style in PhotoViewer

[jackdwo]

The current closing animation of the PhotoViewer is weird and inconsistent with standard modal view animations on mobile devices, resulting in a disjointed user experience. Adding an option to configure the animation style in the PhotoViewer’s settings would allow developers to customize both the opening and closing animations to better align with native modal animations, providing a more cohesive experience.

I also use this plugin in real projects and know about the different user experience ))
@jackdwo What animation do you suggest to be the default?

[jackdwo]

I hope the default modal view opening and closing animation to be a slide up/down transition like iOS. @bazuka5801

@jackdwo I agree, the closing animation is weird.

Agree closing animation is weird, it should rather animate back down than to the side. Maybe better to add an option for close direction.

My solution is to edit

photoviewer/ios/Plugin/Extensions/UIViewController.swift

and change transition.type = CATransitionType.push to transition.type = CATransitionType.reveal

@skle I tested it but the animation is still weird. It does not animate back down when pressing the cross button.

Ok so I found the solution, @skle the change from transition.type = CATransitionType.push to transition.type = CATransitionType.reveal is necessary (that removes half of the weird behavior).

Then, it's necessary to change self.dismissWithTransition(swipeDirection: "no") to self.dismissWithTransition(swipeDirection: "down") in the method closeButtonTapped() in photoviewer/ios/Plugin/OnePhoto/OneImageViewController.swift.

And to change self.dismissWithTransition(swipeDirection: "no") to self.dismissWithTransition(swipeDirection: "down") in the method closeButtonTapped() in photoviewer/ios/Plugin/PhotoSlider/SliderViewController.swift.

There is also a method called closeButtonTapped() in photoviewer/ios/Plugin/PhotoGallery/CollectionViewController.swift but I didn't modify it and it still works perfectly.
