我整个下午都被这个问题困住了。我制作了一个自定义 UIViewController。到目前为止，我在这个自定义视图控制器中显示了自定义视图。一切都好。现在我想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（.
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）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];
但没有运气，如图所示：
自定义视图控制器位于日历视图下方。日历视图应该在自定义视图控制器内部而不是外部。此外，我怎样才能把脊椎放在上面？
[已解决] 没关系：第一个答案是正确的。我的错误是错误的框架设置。
