自定义 UIViewController 内的 UIPageViewController

Question

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，我在这个自定义 View Controller 中显示了自定义 View 。一切都很好。现在我想做的是在自定义 Controller 内显示一个 pageviewcontroller。没有错误，但是页面 Controller 的 View 显示在自定义 Controller 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(按照第一个答案中的建议)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 View Controller 位于日历 View 下方。日历 View 应该位于自定义 View Controller 内部而不是外部。 另外，怎样才能把书脊放在上面呢？

[已解决] 没关系:第一个答案是正确的。我的错误是框架设置错误。

我遇到了完全相同的问题。在调用 didMoveToParentViewController: 之前设置页面 View Controller 的框架应该可以解决它。
