Empty data source does not show when I call deleteRows

[Sweeper777]

I added an empty data source like this:

    collectionView.emptyDataSetView { (view) in
        view.titleLabelString(NSAttributedString(string: "Nothing to see here!"))
        view.shouldDisplay(true)
    }

And I used deleteItems to delete the items one by one. After deleting the last item, I expected the empty data source to show up, but it does not. Bug?

It's look like a bug. When deleteItems, reload will not be executed. It can be solved by swizzling method deleteItems to caculate number of items and then loading emptyDataSet. But DZNEmptyDataSet didn't do this, I dont know why

I also noticed that the empty data source view does not disappear when I add a row/item to an empty table view/collection view. Probably the same issue as this.
