notification when user moves map

Armandvan_der_Zwan — Wed, 12 Aug 2015 08:46:24 GMT

Hi all,

I can't seem to find a way to get notified when the user has moved the map.

I want to know this, because when he/she did, I don't want to update the map to the user location anymore.

Any idea's?

Armand.

Can you be more specific

What software?
Do you mean move it within the software? or removed offsite?
Do you want to include moves without saving or with?
Are notifications to be kept in a log file or do you want real time notification?

Elaborations would be useful.

Sorry, I'm on the iOS SDK, Objective-C.

So when a user moves the map with his finger, I would like to be notified.

Hi Armand van der Zwan,

I'll assume this is for version 10.2.4

You can try implementing AGSMapViewTouchDelegate and using one of the didMoveTapAndHoldAtPoint: methods. This way you will know when the user stops panning the map.

But I don't quite understand what you mean by don't wan't to update the map to user location.

Can you explain in more detail please.

regards,

David

Thanks. I will look into it.

I want the map not to center to the user location the moment the user moves the map.

didMoveTapAndHoldAtPoint is not triggered when the user is moving the map...

I got it working with:

// register for pan notifications

[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(respondToEnvChange:)

name:AGSMapViewDidEndPanningNotification object:nil];

Still not working. I can't figure out if the zoom/pan is user initiated, or otherwise.

Hey Armand van der Zwan,

Take a look at lastChangeFromInteraction on AGSMapView (it's inherited from AGSMapViewBase).

When you receive the AGSMapViewDidEndPanningNotification or AGSMapViewDidEndZoomingNotification notification, check that and it should tell you what you want.

Hope that helps,

Nick.
