Answer 1

I really spend a lot of time trying to solve this problem, at last I found the way. I just ask a question and answer it myself to share the solution here.

Pls refer my blog to get more detail enter link description here

Demo code:

#import "TestNavigationController.h"

@interface _UINavigationInteractiveTransition

@end

@interface UINavigationController(Custom)
@property (strong, nonatomic) _UINavigationInteractiveTransition * _cachedInteractionController;

@end

@implementation TestNavigationController
{
    UIPanGestureRecognizer *_p;
}

- (void)viewDidLoad {
    [super viewDidLoad];
    NSLog(@"%@", self.interactivePopGestureRecognizer
          );
    _p = [[UIPanGestureRecognizer alloc]initWithTarget:self._cachedInteractionController action:@selector(handleNavigationTransition:)];
    NSLog(@"%@", self._cachedInteractionController);
    [self.view addGestureRecognizer:_p];
   } 
@end
