we upgraded Xamarin Forms iOS from 4.2 to 4.7 and observed the following behaviour change in MasterDetailPage:
We have a MasterDetailPage. Master is a side panel with menu items and in Detail there is a NavigationPage with a list view.
In Forms 4.2, when the list view in Detail is visible, we could drag with the finger on the screen from left to right to drag the side panel into the screen. When we lift the finger up from the screen, the side panel will be presented fully. We can drag the side panel back again without triggering the itemTapped/itemSelected of the listview in the Detail Screen.
In Forms 4.7, when we drag with the finger on the list view from left to right and then lift the finger up from the screen, the itemTapped/itemSelected is triggered of the listview for the item where the finger was touched. That's bad. Everytime when I drag in the side panel, I activate an list item and you see the animation to the next page on right area of the screen.
This behaviour is not desired and I think this is a bug, or? Is there a workaround for it, with CustomRenderers?
On Android, this is not a problem. The side panel can be dragged in by dragging from the left edge to the right without triggering the itemselected of the list view. This works in Forms 4.2 and 4.7.
