问题关于检测Mapkit可用性

创建的应用用到了Mapkit，好像只能在ios6中，所以想检测一下是不是Mapkit可用。代码如下：

 if(NSClassFromString(@""MKMapKit"")) {        // MKMapKit在此OS可用        CLLocationCoordinate2D coords =        CLLocationCoordinate2DMake(51.0971855.621653);        NSDictionary *address = @{        (NSString *)kABPersonAddressStreetKey: @""Weg naar oqdffds 59""        (NSString *)kABPersonAddressCityKey: @""Msfsf""        (NSString *)kABPersonAddressStateKey: @""Limbusqfqsdf""        (NSString *)kABPersonAddressZIPKey: @""3670""        (NSString *)kABPersonAddressCountryCodeKey: @""BE""        (NSString *)kABPersonPhoneMainLabel:@""04741234567""        };        MKPlacemark *place = [[MKPlacemark alloc]                              initWithCoordinate:coords addressDictionary:address];        MKMapItem *mapItem = [[MKMapItem alloc]initWithPlacemark:place];        mapItem.phoneNumber = @""0141343252"";        //当前位置        MKMapItem *mapItem2 = [MKMapItem mapItemForCurrentLocation];        NSArray *mapItems = @[mapItem mapItem2];        NSDictionary *options = @{            MKLaunchOptionsDirectionsModeKey:MKLaunchOptionsDirectionsModeDriving            MKLaunchOptionsMapTypeKey:            [NSNumber numberWithInteger:MKMapTypeStandard]            MKLaunchOptionsShowsTrafficKey:@YES        };        [MKMapItem openMapsWithItems:mapItems launchOptions:options];    }else {        NSLog(@""tot hier"");        // MKMapKit在此OS不可用        locationController = [[MyCLController alloc] init];        locationController.delegate = self;        [locationController.locationManager startUpdatingLocation];    }

但是不知道为什么它总是用Google的方法，请帮忙。谢谢
