UIPageViewController里面有一个自定义的UIViewController

我整个下午都被这个问题困扰了 . 我做了一个自定义的UIViewController . 到目前为止，我在此自定义viewcontroller中显示了自定义视图 . 一切都很好 . 现在我想要做的是在自定义控制器中显示一个pageviewcontroller . 没有错误，但是页面控制器的视图显示在自定义控制器的边界之外（ .

这是我的代码

- (void)viewDidLoad
{
[super viewDidLoad];
self.monthYearController = [[avvAgendaMonthViewController alloc] init];
self.yearViewController  = [[avvAgendaYearViewController alloc] init];
self.pager               = [[UIPageViewController alloc]   initWithTransitionStyle:UIPageViewControllerTransitionStylePageCurl
  navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal
                            options:nil];

//Assign the delegate and datasource .
self.pager.delegate = self;
self.pager.dataSource = self;

//Set the initial view controllers.
NSArray *viewControllers = [NSArray arrayWithObject:self.yearViewController];
[self.pager setViewControllers:viewControllers
            direction:UIPageViewControllerNavigationDirectionForward
            animated:NO
            completion:nil];



//Add the pageViewController as the childViewController
[self addChildViewController:self.pager];
[self.view addSubview:self.pager.view];

[self.pager didMoveToParentViewController:self];
CGRect pageViewRect = self.view.bounds;
pageViewRect = CGRectInset(pageViewRect, 40.0, 40.0);
self.pager.view.frame = pageViewRect;


//Assign the gestureRecognizers property of our pageViewController to our view's gestureRecognizers property.
self.view.gestureRecognizers = self.pager.gestureRecognizers;

这是界面（非常简单）：

@interface CustomNavigatorViewController : UIViewController      <CustomNavigationDelegate,UIPageViewControllerDataSource,UIPageViewControllerDelegate>

@property (nonatomic,strong) CustomNavigation* navigation;
@property (nonatomic,strong) UIPageViewController *pager;
@property (nonatomic,strong) AgendaYearViewController* yearViewController;
@property (nonatomic,strong) AgendaMonthViewController* monthYearController;
@property (nonatomic,strong) UIViewController* agendaCurrentView;


@end

我尝试（如第一个答案中所建议的）在最后调用didMoveToParentViewController：

CGRect pageViewRect = self.view.bounds;
pageViewRect = CGRectInset(pageViewRect, 40.0, 40.0);
self.pager.view.frame = pageViewRect;
[self.pager didMoveToParentViewController:self];

但如图所示没有运气：

自定义视图控制器位于日历视图下方 . 日历视图应位于自定义视图控制器内，而不是外部 . 而且，我怎样才能将脊柱放在上面？

[求助]没关系：第一个答案是对的 . 我的错误是错误的框架集 .
