I want to show all the markers that are on my map, after doing some searches I found that it should be done with GMSCoordinateBounds (Google Maps SDK) I\'ve
We can find the same code every where , but make sure that it is in viewDidAppear() method
//bounding to a region of markers
GMSCoordinateBounds *bounds =
[[GMSCoordinateBounds alloc] initWithCoordinate:sourceMarker.position coordinate:destMarker.position];
[_mapView moveCamera:[GMSCameraUpdate fitBounds:bounds withPadding:50.0]];
