Reload data workaround for UIPageViewController

UIPageViewController+ReloadData.h

#import <UIKit/UIPageViewController.h>

// Because UIPageViewController somehow "caches" its view controllers when you pass animated:YES and there is no "reloadData" method in UIPageViewControllerDataSource

@interface UIPageViewController (ReloadData)

- (void) xcd_setViewControllers:(NSArray *)viewControllers direction:(UIPageViewControllerNavigationDirection)direction animated:(BOOL)animated completion:(void (^)(BOOL))completion;

@end

UIPageViewController+ReloadData.m

#import "UIPageViewController+ReloadData.h"

@implementation UIPageViewController (ReloadData)

- (void) xcd_setViewControllers:(NSArray *)viewControllers direction:(UIPageViewControllerNavigationDirection)direction animated:(BOOL)animated completion:(void (^)(BOOL))completion
{
	void (^reloadData)(BOOL) = ^void(BOOL finished) {
		dispatch_async(dispatch_get_main_queue(), ^{
			[self setViewControllers:viewControllers direction:direction animated:NO completion:completion];
		});
	};
	
	[self setViewControllers:viewControllers direction:direction animated:animated completion:animated ? reloadData : completion];
}

@end

What do you think about this? looks like just another workaround, not sure which is better

- (void)reloadData
{
    self.pageViewController.dataSource = nil;
    self.pageViewController.dataSource = self.channelsDataSource;
}

@MrBoog it doesn't work!

I noticed that using animated = false is enough to "delete" the cache.
