MMDrawerController：檢測菜單關閉操作或刷卡手勢

Question

我想檢測菜單何時關閉。我發現這個解決了question。在接受答案的評論，他們說，這種方法：

-(void)setGestureCompletionBlock:(void(^)(MMDrawerController * drawerController, UIGestureRecognizer * gesture))gestureCompletionBlock; 

必須在App delegate，以通知當菜單關閉。我把這個函數放在我的應用程序委託中，在它的實現中，我做了一個NSLog(@"menu closed");，但是在我的控制檯中沒有打印任何內容，並且在關閉菜單時該功能未被觸發。

任何人都可以解釋我請如何檢測菜單是否關閉？ （根據給定的答案，或者如果您有其它的）

編輯：

在故事板，我有鏈接到其類型的MMDrawerController（myVCMMdrawerController）的UIViewController的一個UINavigationController的，那麼我也myCenterVC，leftVC和rightVC。在myVCMMdrawerControllerviewDidLoad這是我做的：

MyCenterVC * centerVC = [[self storyboard] instantiateViewControllerWithIdentifier:@"myCenterVC"]; 
    centerVC.drawerController = self; 

    LeftVC * leftVC = [[self storyboard] instantiateViewControllerWithIdentifier:@"leftVC"]; 
    leftVC.drawerController = self; 

    self.centerViewController = centerVC; 
    self.leftDrawerViewController = leftVC; 


    self.showsShadow = false; 
    //[self setMaximumLeftDrawerWidth:[UIScreen mainScreen].bounds.size.width animated: true completion: nil]; 

    //enable gesture 
    self.openDrawerGestureModeMask = MMOpenDrawerGestureModeAll; 
    self.closeDrawerGestureModeMask = MMCloseDrawerGestureModeAll; 
    [self closeDrawerAnimated:NO completion:nil]; 

在myCenterVC我做出的行動來顯示這樣的IBActions菜單：

[self.drawerController toggleDrawerSide:MMDrawerSideLeft animated:true completion:nil];

這裏是爲我的作品的代碼：

Swift 3.0+

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool { 
    // Override point for customization after application launch. 
    let leftDrawer = UIViewController() 
    leftDrawer.view.backgroundColor = UIColor.red 
    let centerDrawer = UIViewController() 
    centerDrawer.view.backgroundColor = UIColor.green 

let mainContainer = MMDrawerController(center: centerDrawer, leftDrawerViewController: leftDrawer) 

mainContainer?.openDrawerGestureModeMask = .panningCenterView 
mainContainer?.closeDrawerGestureModeMask = .panningCenterView 

mainContainer?.setGestureCompletionBlock({ (drawer, gesture) in 
    if drawer?.openSide != .left { 
     print("Drawer Closed") 
    }else { 
     print("Drawer Opened") 
    } 
}) 

window?.rootViewController = mainContainer 
window?.makeKeyAndVisible() 

return true 

}

您可能需要確保您設置

mainContainer?.openDrawerGestureModeMask = .panningCenterView 
mainContainer?.closeDrawerGestureModeMask = .panningCenterView 

，並檢查是否drawer's openSide is left否則其關閉。

Objective-C的

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 
    // Override point for customization after application launch. 

    UIViewController *leftDrawer = [[UIViewController alloc] init]; 
    [[leftDrawer view] setBackgroundColor:[UIColor redColor]]; 
    UIViewController *centerDrawer = [[UIViewController alloc] init]; 
    [[centerDrawer view] setBackgroundColor:[UIColor greenColor]]; 

    MMDrawerController *mainDrawer = [[MMDrawerController alloc] initWithCenterViewController:centerDrawer leftDrawerViewController:leftDrawer]; 
    mainDrawer.openDrawerGestureModeMask = MMOpenDrawerGestureModePanningCenterView; 
    mainDrawer.closeDrawerGestureModeMask = MMOpenDrawerGestureModePanningCenterView; 

    [mainDrawer setGestureCompletionBlock:^(MMDrawerController *drawerController, UIGestureRecognizer *gesture) { 
     if (drawerController.openSide != MMDrawerSideLeft) { 
      NSLog(@"Drawer Closed"); 
     }else{ 
      NSLog(@"Drawer Opened"); 
     } 
    }]; 

    self.window.rootViewController = mainDrawer; 
    [self.window makeKeyAndVisible]; 

    return YES; 
}
