Question

我做了一个UIPageViewController多个UIViewController。现在，我需要在UIView中的顶部和底部添加一个固定的UIPageViewController ...

我的代码是：

   - (void)viewDidLoad
{
    [super viewDidLoad];

    // Create it.
    self.pageController = [[UIPageViewController alloc] initWithTransitionStyle:UIPageViewControllerTransitionStyleScroll navigationOrientation:UIPageViewControllerNavigationOrientationHorizontal options:nil];

    // Point the datasource back to this UIViewController.
    self.pageController.dataSource = self;

    // Assuming you have a SomePageViewController which extends UIViewController so you can do custom things.


    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];
    if(!self.roteirosView)
        self.roteirosView = [sb instantiateViewControllerWithIdentifier:@"RoteirosView"];

    self.initialViewControllers = [NSArray arrayWithObject:self.roteirosView];

    // animated:NO is important so the view just pops into existence.
    // direction: doesn't matter because it's not animating in.
    [self.pageController setViewControllers:self.initialViewControllers direction:UIPageViewControllerNavigationDirectionForward animated:NO completion:nil];

    // Tell the child view to get ready
    [self.pageController willMoveToParentViewController:self];

    // Actually add the child view controller
    [self addChildViewController:self.pageController];

    // Don't forget to add the new root view to the current view hierarchy!
    [self.view addSubview:self.pageController.view];

    // And make sure to activate!
    [self.pageController didMoveToParentViewController:self];
}

- (void)viewDidLayoutSubviews {
}

- (UIViewController *)viewControllerAtIndex:(int)i {
    // Asking for a page that is out of bounds??
    if (i<0) {
        return nil;
    }
    if (i>=MAX_PAGES) {
        return nil;
    }

    // Assuming you have SomePageViewController.xib
    UIStoryboard *sb = [UIStoryboard storyboardWithName:@"Main" bundle:nil];

    if (i == 0) {
        if(!self.roteirosView)
            self.roteirosView = [sb instantiateViewControllerWithIdentifier:@"RoteirosView"];
        return self.roteirosView;
    }
    else {
        if(!self.pertoView)
            self.pertoView = [sb instantiateViewControllerWithIdentifier:@"PertoView"];
        return self.pertoView;
    }
}


- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController {
    UIViewController *p = (UIViewController *)viewController;
    if ([p isKindOfClass:[PertoViewController class]]) {
        return [self viewControllerAtIndex:0];
    }
    else {
        return [self viewControllerAtIndex:MAX_PAGES]; // permanece na mesma página
    }

}


- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController {
    UIViewController *p = (UIViewController *)viewController;
    if ([p isKindOfClass:[PertoViewController class]]) {
        return [self viewControllerAtIndex:MAX_PAGES]; // permanece na mesma página
    }
    else {
        return [self viewControllerAtIndex:1];
    }
}

在我的UIStoryBoard我有HomesViewController，它是我的UIPageViewController，PertoViewController和RoteirosViewController。两个UIViewControllers都添加UIPageViewController。

Answer 1

在UIPagerViewController类的viewDidAppear中添加你要添加的2个UIViews，这应该在2个视图控制器的已加载视图上添加新视图。

如果这对你没有用，请确保你也不是通过代码而不是故事板添加2视图控制器，并确保先添加它们然后添加2个视图标题和底部标题，以确保它们在屏

希望这个答案可以帮助你，祝你好运
