you can pan map or change perspective little latency. bearing, tilt, location , zoom level of map can controlled programmatically via gmscameraposition object.
you can use -animatetozoom: on gmsmapview, or can create gmscameraposition , set coordinate , zoom level , use -animatetocameraposition: or create gmscameraupdate , use -animatewithcameraupdate:
gmscameraposition *cameraposition = [gmscameraposition camerawithlatitude:latitude longitude:longitude zoom:11.0]; [self.mapview animatetocameraposition:cameraposition]; or
gmscameraupdate *update = [gmscameraupdate zoomto:11.0]; [self.mapview animatewithcameraupdate:update]; or
[self.mapview animatetozoom:11.0];
