xCode 6 using UIPageViewController and swift changing view size - ios

Question

I'm loading views into a UIPageViewController and scrolling through them horizontally.
My issue is that when a view enters screen, it has a bigger size, and when the scroll finishes, it snaps to the size it should have.
Been trying to figure this out for a couple of hours now.
Anyone has had the same problem? how did you solve it?
I've checked these 2 links:
UIPageViewController changes size?
UIPageViewController has strange size
That made sense, but on my case, by doing that, I made the views too big on smaller devices, feels like the constraints aren't working, so I'm getting the bigger size here

Answer 1

I am not sure but try this:
// Disalbe translatesAutoresizingMaskIntoConstraints
self.pageViewController.view.translatesAutoresizingMaskIntoConstraints = NO;
// Set up page view controller view constraints by using PureLayout
[self.pageViewController.view autoPinEdgesToSuperviewEdgesWithInsets:UIEdgeInsetsZero]

Answer 2

please confine is it help ful or not ..
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerBeforeViewController:(UIViewController *)viewController
{
ImageViewController *contentVc = (ImageViewController *)viewController;
NSUInteger currentIndex = [_modelArray indexOfObject:[contentVc model]];
_vcIndex = currentIndex;
[_rateStepper setValue:[[contentVc model] rating]];
ImageModel *model = [_modelArray objectAtIndex:_vcIndex];
[_imageLabel setText:[NSString stringWithFormat:#"%# - Rating: %d", model.imageName, model.rating]];
if (currentIndex == 0)
{
return nil;
}
ImageViewController *imageViewController = [[ImageViewController alloc] init];
imageViewController.model = [_modelArray objectAtIndex:currentIndex - 1];
return imageViewController;
}
- (UIViewController *)pageViewController:(UIPageViewController *)pageViewController viewControllerAfterViewController:(UIViewController *)viewController
{
ImageViewController *contentVc = (ImageViewController *)viewController;
NSUInteger currentIndex = [_modelArray indexOfObject:[contentVc model]];
_vcIndex = currentIndex;
[_rateStepper setValue:[[contentVc model] rating]];
ImageModel *model = [_modelArray objectAtIndex:_vcIndex];
[_imageLabel setText:[NSString stringWithFormat:#"%# - Rating: %d", model.imageName, model.rating]];
if (currentIndex == _modelArray.count - 1)
{
return nil;
}
ImageViewController *imageViewController = [[ImageViewController alloc] init];
imageViewController.model = [_modelArray objectAtIndex:currentIndex + 1];
return imageViewController;
}
If you build and run now, the pages will scroll, however we are still missing the page indicator view. We only need to implement the following dataSource methods as below:
- (NSInteger)presentationCountForPageViewController:(UIPageViewController *)pageViewController
{
return _modelArray.count;
}
- (NSInteger)presentationIndexForPageViewController:(UIPageViewController *)pageViewController
{
return 0;
}
