65th, iOS7 custom transitions Animation

Custom transitions animations are only beginning to appear in iOS7 and above, and in some applications we often need to customize the jump animations

1. Compliance with the Agreement:<uiviewcontrolleranimatedtransitioning>

2. The main method of the agreement is two:

1. (
2. (void) Animatetransition: (ID <UIViewControllerContextTransitioning>) transitioncontext;

Use the method of complying with the NAV agreement:

#pragmaMark-uinavigationcontrollerdelegate-(ID<UIViewControllerInteractiveTransitioning>) Navigationcontroller: (Uinavigationcontroller *) Navigationcontroller Interactioncontrollerforanimationcontroller: (ID<UIViewControllerAnimatedTransitioning>) Animationcontroller {returnNil;}- (ID<UIViewControllerAnimatedTransitioning>) Navigationcontroller: (Uinavigationcontroller *) Navigationcontroller animationcontrollerforoperation: (uinavigationcontrolleroperation) operation Fromviewcontroller: (Uiviewcontroller *) Fromvc Toviewcontroller: (Uiviewcontroller *) ToVC {if(Operation = =Uinavigationcontrolleroperationpush) {    return[Hybcontrollertransition transitionwithtype:kcontrollertransitionpush Duration:0.75]; } Else {    return[Hybcontrollertransition transitionwithtype:kcontrollertransitionpop Duration:0.75]; }}
