Google Maps for iOS - How can you tell if a marker is within the bounds of the screen?

Question

I\'m trying to figure out a straightforward way to determine in Google Maps for iOS if a given GMSMarker is within the bounds of the visible map. There seems to be solution

Answer 1

I have written on method to find GMSMarker is in particular frame. Set your rectangle frame (x,y,maxX,maxY). You can set any frame from screen it tell find marker is in that frame or not..

- (BOOL)isGoogleMapMarkerVisible:(GMSMarker*)marker {

    //Marker point
    CGPoint markerpoint = [self.mapview.projection pointForCoordinate:marker.position];

    //Maximum visible region from x and y axis
    float x = 0.0;
    float y = o.o;
    float maxX = self.mapview.frame.size.width;
    float maxY = self.mapview.frame.size.height;

    //If marker point is on visible region return true else return false
    if (markerpoint.x > x && markerpoint.y > y && markerpoint.x < maxX && markerpoint.y < maxY) {
        return YES;
    }
    else {
            return NO;
    }
}
