  • strange behavior when embedded in navigation-controller

    strange behavior when embedded in navigation-controller

    Hey,

    i am using a ViewController, which is embedded in a NavigationController. Inside of that ViewController, i have a CollectionView that uses the SFFocusViewLayout. When i scroll down at a offset of approximately -64 and release my finger, it stops for a short duration and then snaps back to 0 offset. Using a ViewController without a NavigationController solves the issue. I guess calculation goes wrong at some point, when the CollectionView is not at yPosition 0 within the ViewController?

    How do I change the background color of the layout? Change on collectionView.backgroundColor has no effect.

    And is it possible to have the layout end at the bottom of the collectionView? Thanks for the assistance.

  • Specify Swift version without patch (fix #16)

    Specify Swift version without patch (fix #16)

    This fixes #16. Basically it is a workaround for a weird Xcode 8.2 behavior which might not get fixed but instead defined as the new expected behavior, so we should update the framework.

    Xcode 8.2 build issue

    I have just tried to install version 3.1.0 via Carthage but it failed. It looks to me as if this is a similar issue to https://github.com/ninjaprox/NVActivityIndicatorView/pull/102 which is basically a strange Xcode 8.2 behavior. I think specifying only Swift 3.0 instead of 3.0.1 will fix this.

    Change Background

    Is there by any chance a possibility to change the background of the collectionView? In color or Image? Once the user has scrolled through the content, there is a grey space of half the screen. Doesn't look too good. Any idea?
