Can't set initial page

[markst]

It seems that setting the content inset of the scroll view rests the content offset. https://github.com/stefanceriu/SCPageViewController/blob/master/SCPageViewController/SCPageViewController.m#L547

I'm also unable to set the initial page that's loaded before viewDidLoad calls on reloadData which loads the first page.

After loading the view I can set the page with navigateToPageAtIndex: which works until viewWillLayoutSubviews triggers resetting of the content insets (after viewWillAppear:) the above commit resolves this issue for me.

I'm trying to reproduce this viewWillLayoutSubviews problem and getting nowhere. I'm setting the page and then changing the pageViewController's frame so that it triggers a re-layout. I added this to the RootViewController from the Demo project:

- (void)viewWillAppear:(BOOL)animated
{
[self.pageViewController navigateToPageAtIndex:20 animated:NO completion:nil];
[self.pageViewController.view setFrame:CGRectInset(self.view.bounds, 10, 10)];
}

Everything seems to be where I expect it to be so is there anything else that you're doing differently ?

As for setting the page before the view controller is loaded, you really shouldn't do that. Firstly because the scrollView isn't instantiated yet so there's nothing to set a contentOffset on and secondly because these page calculations rely on the pageViewController's bounds which won't necessarily be correct at that point. Any reason why you can't delay this current page setting until everything is set up properly ?

this is still an issue for me.

@stefanceriu it's still happening.

Only possible to set initial page on viewDidAppear, and it's too late.

This last commit should address the problem. Have a look and let me know, if it's all good I'll push it to master and release a new version.

I found a way around it by setting a layout:

self.setLayouter(SCPageLayouter(), andFocusOnIndex: index, animated: false) { () -> Void in

}

Thanks. I will check out develop branch.
