(Navigation controller view) full screen swipe for pop effects

See the app now more and more popular gesture sliding to achieve pop effect, in the heart is itching eager, after a multi-view material, finally found in Jane book detailed implementation of the program:

Easy Learning II--ios using runtime custom controller pop gesture animation

Modified to implement a simple (custom navigation Controller) gesture swipe to achieve the pop return effect:

1. The interactivepopgesturerecognizer,log results of the navigation controller are printed first:

<UIScreenEdgePanGestureRecognizer:0x7fe5f1579ce0; state = Possible; Delaystouchesbegan = YES; View = <uilayoutcontainerview 0x7fe5f1567ea0>; target= < (action=handlenavigationtransition:, target=<_uinavigationinteractivetransition

2. Custom Uipangesturerecognizer, counter switch to the target of the gesture and action;action good processing, but Target's live with runtime can be obtained, but the process is slightly complicated,

Print interactivepopgesturerecognizer.delegate; found just as well as _uinavigationinteractivetransition, so problem solving:

ID target = self.interactivePopGestureRecognizer.delegate;

Uipangesturerecognizer *pan = [[Uipangesturerecognizer alloc] Initwithtarget:target action:nsselectorfromstring (@ " Handlenavigationtransition: ")];

3. Test found that if the current navigation controller's self-controller only one time, the drag gesture will be a bug, then need diarrhea pan gesture

-(BOOL) Gesturerecognizershouldbegin: To determine whether the gesture action works:

-(BOOL) Gesturerecognizershouldbegin: (Uigesturerecognizer *) Gesturerecognizer

{

return self.childviewcontrollers.count==1?no:yes;

}
