iOS调用系统自带地图导航

CLLocationCoordinate2D endCoor = CLLocationCoordinate2DMake(startCoor.latitude, startCoor.longitude);

MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];

MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:endCoor addressDictionary:nil]];

toLocation.name = @"to name";

[MKMapItem openMapsWithItems:@[currentLocation, toLocation] launchOptions:@{MKLaunchOptionsDirectionsModeKey:
MKLaunchOptionsDirectionsModeDriving,MKLaunchOptionsShowsTrafficKey: [NSNumber numberWithBool:YES]}];
