  • iOS 10. Dragging cell disappears

    iOS 10. Dragging cell disappears

    Whenever i try to drag a cell by pressing on the top edge of the cell. The cell vanishes and isn't visible in the debug view heirarchy either. Here is what happens:

    The delegate method for willBeginDragging gets called but didEndDraggingAt isn't called and in this particular case ONLY, the following gets printed into the logs:

    "Snapshotting a view that has not been rendered results in an empty snapshot. Ensure your view has been rendered at least once before snapshotting or snapshot after screen updates."

    Here is a screenshot:

    availableHorizontalScroll

    I found a problem when i use your dragger and tableview delete function at the same time. When i try to long press and moving tableviewcell, and HorizontalScroll it , the delete function will be active. So i want to block the HorizontalScroll when i am add delete function .

    Thanks for your libraries.
