RTL语言uipageviewcontroller动画 [英] RTL languages uipageviewcontroller animation

问题描述

我知道这个问题是典型的，并且在论坛上被多次询问，但我仍然无法解决我的问题，所以如果有任何机构可以提供帮助那就太棒了:)

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 :)

我正在用阿拉伯语创建一个书籍应用程序，我需要从右到左执行uipageviewcontroller的转换。这就是我要说的全部。

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.

还有一件事（如果我没有很好地解释自己的话）我确实需要这个线程：如何更改分页卷曲动画的UIPageViewController方向但我无法'我设法制定他们谈到的解决方案，所以如果有人可以解释我或给我一个链接，我可以知道如何做到这一点就足够了:)。

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 :)

推荐答案

可以用这种方式完成

1. 交换pageViewController的数据源代码从 viewControllerBeforeViewController 到 viewControllerAfterViewController

更改 UIPageViewControllerSpineLocationMin 到 UIPageViewControllerSpineLocationMax

要检查，请启动基于页面的应用程序模板a s通用并更改以下内容 ModelController.m

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];
}

并更改 UIPageViewControllerSpineLocationMin 到 UIPageViewControllerSpineLocationMax 并在RootViewController.m中滑动（indexOfCurrentViewController％2 == 0）的条件

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;
}
