回答1:

Try setting the interactive pop gesture recognizer delegate to nil:

self.navigationController.interactivePopGestureRecognizer.delegate = nil;

I have similar problem & got fixed using method from this answer

Simply, did you call

[super viewWillAppear:animated];

when overriding

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    // your other codes goes on
}
