Side menu item is totally blank after click - ios

Question

After opening the side menu, whenever I click any item of it the side menu goes totally blank and displays only a white screen.
How can I solve this issue?

LEFT, RIGHT

[super viewDidLoad];
NavViewController *view;
view = [self.storyboard instantiateViewControllerWithIdentifier:#"navigationView"];
[self.navigationController.view.window insertSubview:view.view atIndex:0];
// Do any additional setup after loading the view, typically from a nib.
