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 :)
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.
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 :)
It can be done in this way
Swap the code of pageViewController's datasource from viewControllerBeforeViewController
to viewControllerAfterViewController
Change UIPageViewControllerSpineLocationMin
to UIPageViewControllerSpineLocationMax
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];
}
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;
}
