The Catransition class implements the transition animation for the layer. You can specify transition effects from a set of predefined transformations or by providing a custom cifilter instance.

2. Define a transition animation
4. Catransition *animation = [catransition animation];
6. Transition animation Duration
8. Animation.duration = 0.2f;
10. Timing function, from beginning to end fluency???
12. Animation.timingfunction=uiviewanimationcurveeaseinout;
14. Transition animation Type
16. Animation.type = Kcatransitionreveal;
18. The direction the transition animation will go
20. Animation.subtype = Kcatransitionfrombottom;
22. The implementation you need when animating
24. Self.tabBarController.tabBar.hidden = YES;
26. Add animations (transition animations are animations added on a layer)
28. Self.tabBarController.tabBar.layer addanimation:animation forkey:@ "animation"];

Description

duration: How long the animation lasts.

timingfunction: I don't understand (who understands that)

Type: Types of transition animations. If you specify a filter property in a custom transition animation, this property is ignored.

There are four types of type:

NSString * Const kcatransitionfade;//gradually disappears NSString * Const kcatransitionmovein;//MOVE in NSString * Const kcatransitionpush;// Translate (so call it) NSString * Const kcatransitionreveal;//revealed

The default type is Kcatransitionfade.

subtype: The direction in which the transition animation will go.

There are four types of Subtpye:

NSString * Const kcatransitionfromright; NSString * Const Kcatransitionfromleft; NSString * Const Kcatransitionfromtop; NSString * Const Kcatransitionfrombottom;

The default direction is nil.

[Self.tabBarController.tabBar.layer addanimation:animation forkey:@ "animation"];

transition animations are added to the layer!

The following several transition animation calls the Apple's private API, note, carefully used after the Apple called back.
