3) uicontroleventtouchdraginside

4) uicontroleventtouchdragoutside

Unlike uicontroleventtouchdraginside, when dragging, the mouse is out of the control boundary range.

When the mouse is already out of the control, the uicontroleventtouchdragoutside event will continue to be dragged.

The specific operation is to press the mouse in the control and drag it out of the control.

5) uicontroleventtouchdragenter

It refers to the event generated during the drag action from outside the control boundary to the inner.

6) uicontroleventtouchdragexit
