iphone - 在 App Delegate 中，我需要释放我的 "window"和 "navigationController"吗？

Question

我在 App Delegate 中:

1. 需要释放我的“window”和“navigationController”吗？和
2. 我应该在哪里从 (a) applicationDidReceiveMemoryWarning 和 (b) dealloc 中释放它？

代码 list

@interface weekendviewerAppDelegate : NSObject <UIApplicationDelegate> {
    UIWindow                        *window;
    UINavigationController          *navigationController;
}
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UINavigationController *navigationController;

@implementation weekendviewerAppDelegate
@synthesize window;
@synthesize navigationController;

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    
    RootViewController *rootViewController = (RootViewController *)[navigationController topViewController];
    rootViewController.managedObjectContext = self.managedObjectContext;
    self.window.rootViewController = self.navigationController;

    // Configure and show the window
    [window addSubview:[navigationController view]];
    [window makeKeyAndVisible];

    return YES;
}

正如 Bolt 时钟所评论的，您需要在 appDelegate 类中添加一个 dealloc 方法。

- (void)dealloc {

    [navigationController release];
    [window release];
    [super dealloc];
}
