Core Animation Catransition (transition animation)

Used to animate transitions, which gives the layer an animated effect of moving out of the screen and moving into the screen. iOS has less transition animations than Mac OS X

Uinavigationcontroller is the animation effect of pushing the controller's view into the screen via catransition

Attribute parsing:

Type: Animation transition types

Subtype: Animation transition Direction

Startprogress: Start of Animation (percentage in overall animation)

Endprogress: End of Animation (percentage in overall animation)

Code One:
