The issue I mentioned was fixed was text selection realted issue introduced with iOS6. Namely, the selection was taking precedence over long touch events and in terms preventing this event from firing.
There were two implications:
-- Users would not be able to drag and drop a tree node;
-- Users would not be able to show context menu.
With the fix available, the long touch event is not possible.
However, there are three things that can happen on long touch:
-- drag drop
-- node editing
-- context menu
Depending on the actual settings [of the treeview], either drag drop or node editing will be triggered, with drag and drop having higher precedence.
The context menu event [for mobile] is not currently implemented in the treeview, but should you have a custom long touch (tap and hold) event handler it will work.
As a final note, it all very well depends on the actual browser you are using. Though both Safari and Chrome for iOS use the same engine (webkit) there are differences between the actual behaviour of the two browsers.
All the best,
