UIpageviwcontroller在第一次加载视图时仅在横向模式下加载单个视图

我需要帮助UIpageviewcontroller以获得通用应用程序。我在我的应用程序中添加了这项功能，但它工作正常，但是当我在横向模式下第一次加载UIpageviewcontroller时，它仅显示单一视图。我的问题是，如果设备处于横向模式，它只会在第一次加载单面视图。我认为它是因为UIpageviewcontroller的声明代码。UIpageviwcontroller在第一次加载视图时仅在横向模式下加载单个视图

码 - ：

self.Pagecontrol = [[UIPageViewController alloc] initWithTransitionStyle:style 
navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:options]; 



    self.Pagecontrol.delegate = self; 

    self.Pagecontrol.dataSource = self; 


    //Step 3: 
    //Set the initial view controllers. 

    PageCurlView *contentViewController = [[PageCurlView alloc] init]; 

     NSArray *viewControllers = [NSArray arrayWithObject:contentViewController]; 
    // &&& i add single view controller at time of declaration. 

    CGRect pageViewRect = CGRectMake(self.view.frame.origin.x+15, self.view.frame.origin.y+15, self.view.frame.size.width-45, self.view.frame.size.height-35); 
    pageViewRect = CGRectInset(pageViewRect, 5.0, 20.0); 
    self.Pagecontrol.view.frame = pageViewRect; 


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


    //Step 4: 
    //ViewController containment steps 
    //Add the pageViewController as the childViewController 
    [self addChildViewController:self.Pagecontrol]; 

    //Add the view of the pageViewController to the current view 


    [self.BaseScrollView addSubview:self.Pagecontrol.view]; 
    [self.view addSubview:self.BaseScrollView]; 

    [self.Pagecontrol.view bringSubviewToFront:self.BaseScrollView]; 


    [self.Pagecontrol didMoveToParentViewController:self]; 

    //Step 5: 
    // set the pageViewController's frame as an inset rect. 


    //Step 6: 
    //Assign the gestureRecognizers property of our pageViewController to our view's gestureRecognizers property. 

self.Pagecontrol.view.gestureRecognizers = self.Pagecontrol.gestureRecognizers;

//任何一个可以帮助我解决这个问题。

我很感激你提前帮忙。

，但是当我把这个线获取当前指数它给空数组错误不知道为什么数组是空的 - ：[[自我。 Pagecontrol viewControllers] objectAtIndex：0];如果我设置单个控制器它工作正常 – Anjan

在你的代码我面对这条线上的错误NSUInteger索引= [self indexOfViewController：（contentViewController *）viewController];在这一行上，我得到了viewcontroller的空数组 – Anjan

等几分钟我给了一个样本 – Warewolf
