How to draw GMSPolyline slowly and smoothly in iOS? - ios

Question

I'm able to draw GMSPolyline on GoogleMaps with array of locations like this
GMSMutablePath *path = [GMSMutablePath path];
for (int i = 0; i <anotherArray.count; i++) {
NSString *string1 = [anotherArray2 objectAtIndex:i];
NSString *string2 = [anotherArray objectAtIndex:i];
[path addCoordinate:CLLocationCoordinate2DMake(string1.doubleValue,string2.doubleValue)];
}
GMSPolyline *rectangle = [GMSPolyline polylineWithPath:path];
rectangle.strokeColor = [UIColor blueColor];
rectangle.map = mapView_;
rectangle.strokeWidth = 2.0f;
But the locations I'm getting from backend server.
So I have to refresh every 10 seconds,getting new locations and adding it to existing path. These are all working fine.
But when I am adding new locations to existing path is moving very fast.
Cause I have a GMSMarker at starting of path and it is looking like jumping from one place to another place.
So how can I animate GMSMarker like slowly moving from one place to another place?

Answer 1

Check on this tutorial. It states how to draw the route lines on the map using the GMSPolyline class. From this related SO thread:
Change your else block to be something more like this:
[CATransaction begin];
[CATransaction setAnimationDuration:2.0];
marker.position = coordindates;
[CATransaction commit];
We enable you to use Core
Animation
for animating Google Maps.
For a worked sample, please see
AnimatedCurrentLocationViewController.{c,m} in the SDK sample
application.
Also based from this SO post, avoid using 1px stroke-width of line. Instead, use 4px stroke-width. You can also check on this GitHub sample.
