I am working on bus tarcking app.I draw road of bus with GMSPath class.I need to check specific (latitude,longitude) is in that path or not.I googled,but cannot find method like contain(:latitude:longitude) for checking what I want.I also looked google documentation Please if you know anything about how I can do this,share your experience with me.

The bus might slightly be off path, so you might need to add some tolerance instead of strict containment. Have a look at GMSGeometricUtils.h and more specifically at:

/**
 * Returns whether |point| lies on or near |path|, within the specified |tolerance| in meters.
 * |path| is composed of great circle segments if |geodesic| is YES, and of rhumb (loxodromic)
 * segments if |geodesic| is NO.
 *
 */
BOOL GMSGeometryIsLocationOnPathTolerance(CLLocationCoordinate2D point,
                                          GMSPath *path,
                                          BOOL geodesic,
                                          CLLocationDistance tolerance);
