특정 뷰 컨트롤러에서 탐색 모음을 숨기는 방법

특정 뷰 컨트롤러에서 탐색 모음을 숨기는 방법

---

두 개의 스플래시 화면 iPhone 앱을 만들었습니다. 그 후 사용자는 첫 번째보기로 이동합니다. UINavigationController를 추가했습니다. 완벽하게 잘 작동합니다.

오프닝 뷰에 대한 탐색 모음 만 제거하려면 어떻게합니까?

MainWindow

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {    


self.splashScreen = [[SplashScreen alloc] 
                initWithNibName:@"SplashScreen" 
                bundle:nil];
if (self.pageController == nil) {
openingpage *page=[[openingpage alloc]initWithNibName:@"openingpage" bundle:[NSBundle mainBundle]];
    self.pageController = page;
    [page release];
}
[self.navigationController pushViewController:self.pageController animated:YES];

[window addSubview:splashScreen.view];

 [splashScreen displayScreen];
[self.window makeKeyAndVisible];

return YES;
 }

뷰 컨트롤러 내에서 다음 방법을 시도하십시오.

// swift
self.navigationController?.setNavigationBarHidden(true, animated: true)

// objective-c
[self.navigationController setNavigationBarHidden:YES animated:YES]; 

---

추가 설명 :

UINavigationController 전체 탐색 컨트롤러의 탐색 모음을 숨기거나 표시 할 수있는 navigationBarHidden 속성이 있습니다.

다음 계층 구조를 살펴 보겠습니다.

--UINavigationController
------UIViewController1
------UIViewController2
------UIViewController3

세 UIViewController는 각각 UINavigationController에 있기 때문에 동일한 탐색 모음을 갖습니다. 예를 들어, UIViewController2에 대한 막대를 숨기고 싶을 때 (실제로 어느 것이 든 상관 없음), UIViewController2에 다음과 같이 작성하십시오.

- (void)viewWillAppear:(BOOL)animated {
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES animated:YES];   //it hides the bar
}

- (void)viewWillDisappear:(BOOL)animated {
    [super viewWillDisappear:animated];
    [self.navigationController setNavigationBarHidden:NO animated:YES]; // it shows the bar back
}

스위프트 4 :

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(true)
    navigationController?.setNavigationBarHidden(true, animated: true)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(true)
    navigationController?.setNavigationBarHidden(false, animated: false)
}

---

이것은 나를 위해 일했습니다.

스위프트 4

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    navigationController?.setNavigationBarHidden(true, animated: false)
}

//reappears navigation bar on next page
override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    navigationController?.setNavigationBarHidden(false, animated: true)
}

---

이전에 숨겨 졌는지 기억하는 것이 좋습니다.

private var navigationBarWasHidden = false

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)

    // Save if it was hidden initially
    self.navigationBarWasHidden = self.navigationController?.isNavigationBarHidden ?? false
    // Hide the Navigation Bar
    self.navigationController?.setNavigationBarHidden(true, animated: animated)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)

    // Show the Navigation Bar
    self.navigationController?.setNavigationBarHidden(self.navigationBarWasHidden, animated: animated)
}

---

Use below one line code to hide Navigation bar in Swift3 and Swift4

navigationController?.setNavigationBarHidden(true, animated: true)

To show Navigation bar

navigationController?.setNavigationBarHidden(false, animated: true)

---

In c# or Xamarin.IOS, this.NavigationController.NavigationBar.Hidden = true;

---

Present the opening view modally, or;

1. don't add it to your navigation controller
2. present it before the navigation controller.
3. Once everything has loaded, dismiss the opening view and show the navigation controller (both without animation).

Taking an example from this thread: How can I display a splash screen for longer on an iPhone?

-(void)applicationDidFinishLaunching:(UIApplication *)application {
    [window addSubview:splashView];
    [NSThread detachNewThreadSelector:@selector(getInitialData:) 
                                 toTarget:self withObject:nil];
}

-(void)getInitialData:(id)obj {
    [NSThread sleepForTimeInterval:3.0]; // simulate waiting for server response
    [splashView removeFromSuperview];
    [window addSubview:tabBarController.view];
}
