Question

我的观点结构首先是SWRevealViewController。这需要两个参数。第一个参数是TableViewController看起来很好。第二个参数是pageViewController。 pageViewController有两个＆＃34;页面＆＃34;，每个页面都是NavigationViewController。 NavigationViewControllers将以TableViewControllers作为根视图。

我得到的错误如下：由于未捕获的异常终止应用程序＆＃39; NSInvalidArgumentException＆＃39;，原因：＆＃39;提供的视图控制器数量（2）与数字不匹配要求（1）请求的脊椎位置（UIPageViewControllerSpineLocationMin）＆＃39;

这是我的代码：

（这是我的应用代表）

MyListsViewController *myListsVC = [[MyListsViewController alloc] init];
SidebarViewController *sidebarVC = [[SidebarViewController alloc] init];
StarredTableViewController *starredListsVC = [[StarredTableViewController alloc] init];

// Create page view controller
self.pageViewController = [[UIPageViewController alloc] init];
//self.pageViewController.dataSource = self;

//PageContentViewController *startingViewController = [self viewControllerAtIndex:0];
//UINavigationController *myListsNav = [myListsNav initWithRootViewController:myListsVC];
UINavigationController *myListsNav = [[UINavigationController alloc] initWithRootViewController:myListsVC];
UINavigationController *starredListsNav = [[UINavigationController alloc] initWithRootViewController:starredListsVC];
//NSMutableArray *viewControllers = [[NSMutableArray alloc] init];
NSArray* viewControllers = [NSArray arrayWithObjects: myListsNav, starredListsNav, nil];

[self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

// Change the size of page view controller
self.pageViewController.view.frame = CGRectMake(0, 0, 320, 480);

[self.pageViewController addChildViewController:_pageViewController];
[self.pageViewController.view addSubview:myListsNav.view];
[self.pageViewController didMoveToParentViewController:self.pageViewController];


//UINavigationController *frontNavigationController = [[UINavigationController alloc] initWithRootViewController:myListsVC];
UINavigationController *rearNavigationController = [[UINavigationController alloc] initWithRootViewController:sidebarVC];




// UIScrollView *scrollViews
    SWRevealViewController *revealController = [[SWRevealViewController alloc] initWithRearViewController:rearNavigationController frontViewController:self.pageViewController];

self.window.rootViewController = revealController;

带有两个UINavigationControllers的UIPageView
