iOS 地圖導航

1、ios地圖google map、apple map

#define SYSTEM_VERSION_LESS_THAN(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] == NSOrderedAscending)

- (IBAction)daohang{
    if (SYSTEM_VERSION_LESS_THAN(@"6.0")) { // ios6以下，調用google map
        NSString *urlString = [[NSString alloc] initWithFormat:@"http://maps.google.com/maps?saddr=%f,%f&daddr=%f,%f&dirfl=d",_start.latitude,_start.longitude,_end.latitude,_end.longitude];
        NSURL *aURL = [NSURL URLWithString:urlString];
        [[UIApplication sharedApplication] openURL:aURL];
    } else { // 直接調用ios自己帶的apple map
        CLLocationCoordinate2D to;
        to.latitude = _end.latitude;
        to.longitude = _end.longitude;
        MKMapItem *currentLocation = [MKMapItem mapItemForCurrentLocation];
        MKMapItem *toLocation = [[MKMapItem alloc] initWithPlacemark:[[MKPlacemark alloc] initWithCoordinate:to addressDictionary:nil] ];
        toLocation.name = _end.streetAddres;
        [MKMapItem openMapsWithItems:[NSArray arrayWithObjects:currentLocation, toLocation, nil]
        launchOptions:[NSDictionary dictionaryWithObjects:[NSArray arrayWithObjects:MKLaunchOptionsDirectionsModeDriving, [NSNumber numberWithBool:YES], nil]                        
                                                  forKeys:[NSArray arrayWithObjects:MKLaunchOptionsDirectionsModeKey, MKLaunchOptionsShowsTrafficKey, nil]]];
     }

}

2、iOS mapView 繪製地圖路徑
