In App Delegate:
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
WalkThrough *viewControllers=[[WalkThrough alloc]init];
self.navigationController = [[UINavigationController alloc] initWithRootViewController:viewControllers];
[self.window setRootViewController:self.navigationController];
self.navigationController.interactivePopGestureRecognizer.enabled = NO;
navigationController.navigationBar.hidden = YES;
self.window.backgroundColor = [UIColor clearColor];
[self.window makeKeyAndVisible];
return YES;
}
Try to disable interactivePopGestureRecognizer after [window makeKeyAndVisible]
.
The key to the problem is that interactivePopGestureRecognizer
property is nil
until both two conditions are met:
the navigationController is associated to the window
the window become key and visible
