UIPageViewController中的navigationController pushViewController不起作用

Question

I am new to iOS development. I have story board with a Navigation Controller and UIViewController connect to it.

In UIViewController custom class I add three UIViewController under UIPageViewController :

_one= [self.storyboard instantiateViewControllerWithIdentifier:@"View1"];
_two = [self.storyboard instantiateViewControllerWithIdentifier:@"View2"];
_three = [self.storyboard instantiateViewControllerWithIdentifier:@"View3"];   
_page = [[CustomUIPageViewController alloc] initWithParentViewController:self];
_page.viewControllers = @[_one, _two, _three];
[self.view addSubview:_page.view];
...

I want to show a view from page _two by call this code:

ResultViewController *view = [self.storyboard instantiateViewControllerWithIdentifier:@"ResultBoard"];
        [self.navigationController pushViewController:view animated:YES];

But it not work, I also try:

[self.parentViewController.navigationController pushViewController:view animated:YES];

Answer 1

I can solve my problem now. It is not a "clean" way but it work. On the _two Controller I add:

@property (weak, nonatomic) UINavigationController *navigationCustomController;

And then when init I add:

_two.navigationCustomController = self.navigationController;

After that I just call:

ResultViewController *view = [self.storyboard instantiateViewControllerWithIdentifier:@"ResultBoard"];
[_navigationCustomController pushViewController:view animated:YES];

And it work.
