In my app I have different controllers. When I push controller1 to navigation controller and swipe to back, all works good. But, if I push navigation controller1, and into contr
I solved my problem by UINavigationController interactivePopGestureRecognizer working abnormal in iOS7 and set self.navigationController.interactivePopGestureRecognizer.delegate = self;
on every viewcontroller's
- (void)viewWillAppear:(BOOL)animated
I had same issue and I found below solution. add below controller
#import <UIKit/UIKit.h>
@interface CBNavigationController : UINavigationController <UIGestureRecognizerDelegate,UINavigationControllerDelegate>
@end
#import "CBNavigationController.h"
@interface CBNavigationController ()
@end
@implementation CBNavigationController
- (void)viewDidLoad
{
NSLog(@"%s",__FUNCTION__);
__weak CBNavigationController *weakSelf = self;
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
{
self.interactivePopGestureRecognizer.delegate = weakSelf;
self.delegate = weakSelf;
}
}
- (void)pushViewController:(UIViewController *)viewController animated:(BOOL)animated
{
NSLog(@"%s",__FUNCTION__);
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
self.interactivePopGestureRecognizer.enabled = NO;
[super pushViewController:viewController animated:animated];
}
#pragma mark UINavigationControllerDelegate
- (void)navigationController:(UINavigationController *)navigationController
didShowViewController:(UIViewController *)viewController
animated:(BOOL)animate
{
NSLog(@"%s",__FUNCTION__);
// Enable the gesture again once the new controller is shown
if ([self respondsToSelector:@selector(interactivePopGestureRecognizer)])
self.interactivePopGestureRecognizer.enabled = YES;
}
@end

My solution was to add a delegate to the navigation controller. Then disable the pop gesture recogniser in the root view controller only. YMMV.
#pragma mark - UINavigationControllerDelegate
- (void)navigationController:(UINavigationController *)navigationController didShowViewController:(UIViewController *)viewController animated:(BOOL)animated
{
BOOL isRootVC = viewController == navigationController.viewControllers.firstObject;
navigationController.interactivePopGestureRecognizer.enabled = !isRootVC;
}
Add this code to root navigation controller
func gestureRecognizerShouldBegin(_ gestureRecognizer: UIGestureRecognizer) -> Bool {
return self == self.navigationController?.topViewController ? false : true
}
Add UIGestureRecognizerDelegate protocol
self.navigationController?.interactivePopGestureRecognizer?.delegate = self
self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true
My solution is exchange self.navigationController.interactivePopGestureRecognizer.delegate
between selfImplementDelegate
and SystemDelegate
- (void)viewWillAppear:(BOOL)animated{
[super viewWillAppear:animated];
[_tableView reloadData];
_oldReturnDelegate = self.navigationController.interactivePopGestureRecognizer.delegate;
self.navigationController.interactivePopGestureRecognizer.delegate = self;
}
- (void)viewWillDisappear:(BOOL)animated
{
self.navigationController.interactivePopGestureRecognizer.delegate = _oldReturnDelegate;
[super viewWillDisappear:animated];
}
I would suggest you to try this. This works perfectly for me. You can still enjoy Interactive swipe.
- (BOOL)gestureRecognizerShouldBegin:(UIGestureRecognizer *)gestureRecognizer {
if ([self.navigationController respondsToSelector:@selector(interactivePopGestureRecognizer)] &&
gestureRecognizer == self.navigationController.interactivePopGestureRecognizer) {
if(self.navigationController.viewControllers.count<=1)
{
return NO;
}
}
return YES;
}
