layout transition for supplementary views

[franklixuefei]

Hi Tim,

I'm currently making use of your TLLayoutTransitioning class and it is really easy to use! Thanks a lot for developing this! Actually, I encountered a problem with transition with supplementary views. In my project, instead of only one section, I have two sections in the collection view, and for each section, there is a header view and a footer view. However, after applying your resizing example, the header view and footer view are gone after doing a layout transition (animate cells to be bigger.) I don't think this is an issue with your implementation, but I just have no idea how to accommodate supplementary views in your example (Maybe there is a way to fix it easily which I'm not aware of.). So, if at all possible, could you also add some header view/footer view in your resizing example so that I can study from it? I'm in desperate need of a way to make my project work...

Thanks a lot in advance!

Sincerely,

Frank

Good suggestion. I'm adding support for supplementary views and it should be posted shortly (assuming it works).

Cool that'll be perfect!

Thanks!

Fortunately, I have the day off and I was planning to work on my OSS projects :)

I'll be updating docs and publishing a new podspec shortly, but the support for supplementary views has been added and included in the Resize sample project (enable the "show header views" switch).

To support supplementary views, simply provide a list of supplementary view kinds to the TLTransitionLayout initializer:

- (UICollectionViewTransitionLayout *)collectionView:(UICollectionView *)collectionView transitionLayoutForOldLayout:(UICollectionViewLayout *)fromLayout newLayout:(UICollectionViewLayout *)toLayout
{
    NSArray *supplementaryKinds = @[UICollectionElementKindSectionHeader];
    TLTransitionLayout *layout = [[TLTransitionLayout alloc] initWithCurrentLayout:fromLayout nextLayout:toLayout supplementaryKinds:supplementaryKinds];
    return layout;
}

Re-open the ticket if it doesn't work for you.

I just tried it out and it works perfectly!
