問題描述

我知道這個問題很典型，并且在論壇上被問過很多次，但我仍然無法解決我的問題，所以如果有任何人可以提供幫助，那就太好了:)

I know this question is typique and it was asked many times in the forum, but I still cannot solve my problem, so please if any body can help be that would be GREAT :)

我正在用阿拉伯語創建一個圖書應用程序，我需要執行 uipageviewcontroller 從右到左的轉換.這就是我要說的.

I am creating a book application in the arabic languages and I need to perform the transitions of the uipageviewcontroller from right to left. And thats all I have to say.

還有一件事(如果我沒有很好地解釋我自己的話)我有這個線程的確切需求:如何改變 UIPageViewController 的分頁卷曲動畫方向 但我無法做出他們所說的解決方案，所以如果有人可以解釋我或給我一個鏈接在那里我可以知道如何做到這一點已經綽綽有余了:)

One more thing (if I hadn't explain very well my self) I have the exact need as this thread: How to change UIPageViewController direction of paging curl animation but I couldn't manage to make the solution they spoke about, so if someone can explain me or give me a link where I can have how to do it that would be more than enough :)

推薦答案

這樣就可以了

1. 將pageViewController的數據源代碼從viewControllerBeforeViewController換成viewControllerAfterViewController

將 UIPageViewControllerSpineLocationMin 更改為 UIPageViewControllerSpineLocationMax

要檢查這一點，請將基于頁面的應用程序模板啟動為 Universal 并在 ModelController.m 中更改以下內容

To check that, start Page-Based Application template as Universal and change the following in ModelController.m

- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
    NSUInteger index = [self indexOfViewController:(DataViewController *)viewController];
    if (index == NSNotFound) {
        return nil;
    }

    index++;
    if (index == [self.pageData count]) {
        return nil;
    }
    return [self viewControllerAtIndex:index storyboard:viewController.storyboard];
}

- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
    NSUInteger index = [self indexOfViewController:(DataViewController *)viewController];
    if ((index == 0) || (index == NSNotFound)) {
        return nil;
    }

    index--;
    return [self viewControllerAtIndex:index storyboard:viewController.storyboard];
}

將UIPageViewControllerSpineLocationMin改為UIPageViewControllerSpineLocationMax，在RootViewController.m"中滑動(indexOfCurrentViewController % 2 == 0)的條件

and change UIPageViewControllerSpineLocationMin to UIPageViewControllerSpineLocationMax and swipe the condition of (indexOfCurrentViewController % 2 == 0) in "RootViewController.m"

- (UIPageViewControllerSpineLocation)pageViewController:(UIPageViewController *)pageViewController spineLocationForInterfaceOrientation:(UIInterfaceOrientation)orientation
{
    if (UIInterfaceOrientationIsPortrait(orientation) || ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)) {
        UIViewController *currentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
        NSArray *viewControllers = [NSArray arrayWithObject:currentViewController];
        [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];

        self.pageViewController.doubleSided = NO;
        return UIPageViewControllerSpineLocationMax;
    }

    DataViewController *currentViewController = [self.pageViewController.viewControllers objectAtIndex:0];
    NSArray *viewControllers = nil;

    NSUInteger indexOfCurrentViewController = [self.modelController indexOfViewController:currentViewController];
    if (indexOfCurrentViewController == 0 || indexOfCurrentViewController % 2 == 0) {
        UIViewController *previousViewController = [self.modelController pageViewController:self.pageViewController viewControllerBeforeViewController:currentViewController];
        viewControllers = [NSArray arrayWithObjects:previousViewController, currentViewController, nil];
    } else {
        UIViewController *nextViewController = [self.modelController pageViewController:self.pageViewController viewControllerAfterViewController:currentViewController];
        viewControllers = [NSArray arrayWithObjects:currentViewController, nextViewController, nil];
    }
    [self.pageViewController setViewControllers:viewControllers direction:UIPageViewControllerNavigationDirectionForward animated:YES completion:NULL];


    return UIPageViewControllerSpineLocationMid;
}
