Remove all GMSMarker from GMSMapView?

Question

I placed 100 GMSMarkers on GMSMapView. How to remove all the GMSMarkers?

In Google Sdk Version 1.6 for iOS.

Marker array(in GMSMapView (Overlays) file) which will be holding the GMSMarkers list is deprecated. By using this i was removing all GMSMarker from GMSMapView.

Is there any other way to remove all GMSMarker from GMSMapView in iOS?

Answer 1

Use [mapView clear] to achieve required functionality. :-)

Update:

Swift:

mapView.clear()

Answer 2

They deprecated those methods but you can use [mapView clear] to remove all overlays from the map. This includes all markers, polylines and groundOverlays.

Hope it helps!

Answer 3

Add all markers into NSMutableArray, as you add them to the map. Then when you need to remove them, iterate through the array and set each marker's .map property to nil.

Answer 4

Swift 5.x

If someone is looking to clear only a particular marker then you can use this:

marker.map = nil

If you want to remove everything from the map, like polyline , marker etc. then you can use

self.mapView.clear() .

It will clear everything from the map.

Answer 5

斯威夫特 4.x

self.mapView.clear()

Answer 6

试试……

[self.MapView clear];

Answer 7

You can remove a marker from the map by setting the map property of the GMSMarker to nil .

marker.map = nil

Alternatively, you can remove all of the overlays (including markers) currently on the map by calling the GMSMapView clear method.

mapView.clear()
