iOS：状态栏和导航栏：空间或者下层

Question

如何使用状态栏和导航以规范的方式进行操作？

因此，我的目标是隐藏并出现状态栏和导航栏的同时。

我应该以规范的方式做什么，避免它们之间的空间，避免underlaying（状态栏躺在导航栏上），并支持正常的旋转？

我已经打了它，现在我有一些代码：

-(void)tryToManipulateWithTopBarsIsHidden:(BOOL)hidden{ 
    if (self.wantsFullScreenLayout) { 

     // Get status bar height if visible 

     CGFloat statusBarHeight = 0; 
     [self topBarsHiddenStateAppearingOrDisappearingStatusBarHidden:hidden 
                navigationBarHidden:hidden]; 
     // Get status bar height if visible 
     if (![UIApplication sharedApplication].statusBarHidden) { 
      CGRect statusBarFrame = [[UIApplication sharedApplication] statusBarFrame]; 
      statusBarHeight = MIN(statusBarFrame.size.height, statusBarFrame.size.width); 
//   statusBarOrigin = MIN(statusBarFrame.origin.x,statusBarFrame.origin.y); 
     } 

     // Set navigation bar frame 
     // if status bar is visible and 
     // nav bar origin in y is not the same as status bar (magic, really) 
     // we need to set nav bar origin y to status bar origin y (auto shifting to bottom) 
     CGRect navBarFrame = self.navigationController.navigationBar.frame; 
     // if status bar is visible 
     if (![UIApplication sharedApplication].statusBarHidden){ 
      navBarFrame.origin.y = statusBarHeight; 
      navBarFrame = CGRectOffset(navBarFrame, 0.0, -20.0); 
      self.navigationController.navigationBar.frame = navBarFrame; 
     } 
     self.navigationController.navigationBar.hidden =[UIApplication sharedApplication].statusBarHidden ; 
     LogRect(@"this is statusBar ", [UIApplication sharedApplication].statusBarFrame); 
     LogRect(@"this is navigationBar ", navBarFrame); 
    } 
} 

- (void)setTopBarStatusBarHidden:(BOOL)hidden onCompletion:(void(^)(UINavigationBar*))completion andNavigationBar:(UINavigationBar*)bar{ 
    [[UIApplication sharedApplication] setStatusBarHidden:hidden]; 
    completion(bar); 
} 

- (void)setTopBarNavBarHidden:(BOOL)hidden{ 
    [self.navigationController setNavigationBarHidden:hidden animated:NO]; 
} 

- (void)topBarsHiddenStateAppearingOrDisappearingStatusBarHidden:(BOOL)statusBarHidden 
              navigationBarHidden:(BOOL)navigationBarHidden{ 

    UINavigationBar* bar = self.navigationController.navigationBar; 
    id fles = self; 
    [self setTopBarStatusBarHidden:statusBarHidden 
         onCompletion:^(UINavigationBar *bar) { 
          if (statusBarHidden){ 
           [fles setTopBarNavBarHidden:navigationBarHidden]; 
          } 
          else 
           [fles setTopBarNavBarHidden:navigationBarHidden]; 

         } 
        andNavigationBar:bar]; 
} 

但没有什么！

任何人都可以解释如何解决这个任务没有这个混乱（真的不工作的代码）？

你只是写在方法：

self.navigationController.navigationBar.hidden = YES; 
[UIApplication sharedApplication].statusBarHidden = YES; 

这将隐藏在同一时间，导航栏和状态栏。
