Iphone 第一次加载视图时，UIpageviwcontroller在横向模式下仅加载单个视图

我需要有关

UIpageviewcontroller

的通用应用程序帮助。我将此功能添加到我的应用程序中，它工作正常，但当我第一次以横向模式加载

UIpageviewcontroller

时，它只显示单个视图。我的问题是，若设备处于横向模式，它第一次只加载单个视图。我想这是因为

UIpageviewcontroller

的声明代码

代码-：

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;

//谁能帮我解决这个问题

我感谢你事先的帮助

PVCViewController.h

#import <UIKit/UIKit.h>
#import "ContentViewController.h"


@interface PVCViewController : UIViewController<UIPageViewControllerDataSource>
{
    UIPageViewController *pageController;
    NSArray *pageContent;

}
@property (strong, nonatomic) UIPageViewController *pageController;
@property (strong, nonatomic) NSArray *pageContent;

@end

#import <UIKit/UIKit.h>

@interface ContentViewController : UIViewController
{
    UIPageViewController *pageController;
    NSArray *pageContent;
}
@property (strong, nonatomic) IBOutlet UIWebView *webView;
@property (strong, nonatomic) id dataObject;
@end

将WebView添加到contentViewController xib，并将outlet连接到contentViewController.h文件中的WebView

就这样

这是输出

但当我调用此行获取当前索引时，它给出了空数组错误，我不知道数组为何为空-：[[self.Pagecontrol viewControllers]objectAtIndex:0]；如果我设置了单控制器，它在您的代码中运行良好，我将在这一行遇到错误，即整数索引=[self indexOfViewController:（contentViewController*）viewController]；在这一行中，我得到了viewcontrollerwait的空数组。几分钟后，我将给出一个示例

#import <UIKit/UIKit.h>

@interface ContentViewController : UIViewController
{
    UIPageViewController *pageController;
    NSArray *pageContent;
}
@property (strong, nonatomic) IBOutlet UIWebView *webView;
@property (strong, nonatomic) id dataObject;
@end

#import "ContentViewController.h"

@interface ContentViewController ()

@end

@implementation ContentViewController
@synthesize webView, dataObject;

- (void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [webView loadHTMLString:dataObject
                    baseURL:[NSURL URLWithString:@""]];
}

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization
    }
    return self;
}

- (void)viewDidLoad
{
    [super viewDidLoad];
    // Do any additional setup after loading the view from its nib.
}

- (void)didReceiveMemoryWarning
{
    [super didReceiveMemoryWarning];
    // Dispose of any resources that can be recreated.
}
