1. Get the target object for the system Interactivepopgesturerecognizer object

ID target = self.interactivePopGestureRecognizer.delegate;

2. Create a swipe gesture, Taregt set the target of the Interactivepopgesturerecognizer, so the target action method is automatically called when the interface is sliding.

Handlenavigationtransition is a private class _uinavigationinteractivetransition method, the system is mainly implemented in this method animation.

Uipangesturerecognizer *pan = [[Uipangesturerecognizer alloc] init];

[Pan Addtarget:target action:nsselectorfromstring (@ "handlenavigationtransition:")];

3. Setting up the agent

Pan.delegate = self;

4. Add to the view on the navigation controller

[Self.view Addgesturerecognizer:pan];

5. Disable slide gestures for the system

self.interactivePopGestureRecognizer.enabled = NO;

}

}

#pragma mark-the swipe starts to trigger

-(BOOL) Gesturerecognizershouldbegin: (Uigesturerecognizer *) Gesturerecognizer

{

Uipangesturerecognizer *pan = (Uipangesturerecognizer *) Gesturerecognizer;

Cgpoint Translat = [Pan TranslationInView:pan.view];

if (Translat.x < 0) {

return NO;

}

Only the navigation of the root controller does not require a right-sliding return feature.

if (Self.viewControllers.count <= 1)

{

return NO;

}

return YES;

}

@end

Just wait for you to copy the code.
