touchDelegate

the touchDelegate has method “didTapAtScreenPoint” “didTouchDownAtScreenPoint” “didTouchUpAtScreenPoint”. But when I give “completion(YES)” to “didTouchDownAtScreenPoint”, “didTapAtScreenPoint”  will has no response, and the map can’t be drag.Now I need method “didTapAtScreenPoint” has a response and I need a method to know when a tap or drag gesture start and end and don’t interrupt the gesture. What should I do?

If you respond with YES to didTouchDownAtScreenPoint, you are telling the Runtime that you want to handle the entire tap or drag gesture and so Runtime will not make the map track your finger around the screen. You will then receive didTouchDragToScreenPoint delegate events until the drag gesture completes with a single didTouchUpAtScreenPoint event.

If you respond with NO to didTouchDownAtScreenPoint (or don't implement the delegate method) then Runtime will handle a drag and move the map to accompany the drag gesture, or handle a tap via the didTapAtScreenPoint.

If you just want to detect taps on the map, simply implement the didTapAtScreenPoint delegate method and don't implement didTouchDownAtScreenPoint (or implement it to return NO), didTouchDragToScreenPoint and didTouchUpAtScreenPoint.

Let me know if that helps.
