Support for iOS7+.

• Pop ViewController with pan gesture from middle or edge of screen.

There is a sister library MLNavigationBarTransition(Advanced navigation bar transition based on official push-pop transition)

My library does not seek any reward, but if you use this library, star it if you like. :)

1. This library uses unpublished api (non-private), please use it at your own risk, unpublished APIs do not have official compatibility commitments from iOS.
2. My application has been approved. It is possible that the AppStore will only prohibit the listing of applications that use private APIs and will not strictly treat unpublished APIs, but this is just my guess.

- (BOOL)application:(UIApplication *)application willFinishLaunchingWithOptions:(nullable NSDictionary *)launchOption{
[MLTransition validatePanBackWithMLTransitionGestureRecognizerType:MLTransitionGestureRecognizerTypePan];//or MLTransitionGestureRecognizerTypeScreenEdgePan
//...
return YES;
}
