Question

我为两个视图控制器使用UIPageViewController。在第一个视图控制器中，我有一个＆＃39; NEXT＆＃39;按钮转到第二个视图控制器。我的问题是：我如何连线？

在我的第一个和第二个视图控制器中，我还没有代码。但是，在我的RootViewController中，我有这个代码：

- (void)viewDidLoad {
    self.pageViewController = [self.storyboard instantiateViewControllerWithIdentifier:@"PageViewController2"];
    self.pageViewController.dataSource = self;
    SeekerRegistrasiViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:@"seeker1"];
    Seeker2RegistrasiViewController *pvc;
    self.array =[NSArray arrayWithObjects:tvc, pvc, nil];
    [self.pageViewController setViewControllers:self.array direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:nil];
    self.pageViewController.view.frame = CGRectMake(0, 0, self.view.frame.size.width, self.view.frame.size.height -60);
    self.pageViewController.view.backgroundColor = [UIColor clearColor];
    [self addChildViewController:pageViewController];
    [self.view addSubview:pageViewController.view];
    [self.pageViewController didMoveToParentViewController:self];
}

-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController{
    if ([viewController isKindOfClass:[Seeker2RegistrasiViewController class]]) {
        SeekerRegistrasiViewController *pvc = [self.storyboard instantiateViewControllerWithIdentifier:@"seeker1"];
        return  pvc;
    }
    else return nil;
}



-(UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController{
    if ([viewController isKindOfClass:[SeekerRegistrasiViewController class]]) {
        Seeker2RegistrasiViewController *tvc = [self.storyboard instantiateViewControllerWithIdentifier:@"seeker2"];
        return tvc;
    }
    else return nil;
}

- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController {
    return 2;
}

- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController {
    return 0;
}

我将非常感谢能够指导我朝着正确方向前进的任何帮助。

您可以使用setViewControllers:direction:animated:completion:执行此操作。看看这个答案：Is it possible to Turn page programmatically in UIPageViewController?

您基本上再次设置所有视图控制器（已切换），定义方向（动画将使用的方向，例如UIPageViewControllerNavigationDirectionForward），使用YES进行动画处理，使用完成块进行处理之后（比如更新您管理的currentPage索引）。
