MKPolylineView *polylineView = [[MKPolylineView alloc] initWithOverlay:overlay];
polylineView.lineWidth = 3;
polylineView.strokeColor = [[UIColor alloc] initWithRed:5.0/255 green:102.0/255 blue:48.0/255 alpha:1];
MKCircleView *circleView = [[MKCircleView alloc] initWithOverlay:overlay];
circleView.strokeColor = [UIColor blueColor];
circleView.fillColor = [[UIColor blueColor] colorWithAlphaComponent:0.4];
circleView.lineWidth = 2;
