Get all objects in selected location #801

Closed amirfl closed 7 years ago

amirfl commented 7 years ago

Is there a way to get all objects (instead of just a single object) that are tapped over by the user. I have a few overlapping regions, shown as vector objects on the globe. When the user taps them I'd like to show a menu where he can select the object interested in.

Use the allSelect: delegate instead.

Thanks. I've implemented - (void)globeViewController:(WhirlyGlobeViewController *)viewC allSelect:(NSArray *)selectedObjs atLoc:(MaplyCoordinate)coord onScreen:(CGPoint)screenPt

However, allSelect contains only a single MaplyVectorObject when the user taps on an area with overlapping vectors. I know this method works fine with other objects, because multiple markers are returned when a user taps an area with a close markers.

Make sure you're on a recent version. I believe we just fixed that a few weeks ago.

Just updated to daily build 108 (latest) for iOS, but unfortunately still getting the same problem.

I'm seeing multiple object selection working in a test case. I did have to set MaplyVectorObject.selectable = true.

amirfl commented 7 years ago

still having the problem, but worked around it by searching through all my vector objects and testing which ones had the tap location inside their borders.

The test case I built for this appears to work, so I'm not sure what to suggest.
