iphone - 在 ios 中隐藏 UINavigationBar 的问题

Question

我的应用程序的联系页面中有一个 Split View Controller 。我无法在我的页面中隐藏导航栏。任何人都可以帮助我隐藏导航栏。我附上了我的代码

- (void)viewDidLoad
{
self.navigationController.navigationBarHidden = YES;
splitViewController.navigationController.navigationBarHidden = YES;

appdelegate = (AppDelegate*)[[UIApplication sharedApplication]delegate]; 

[super viewDidLoad];

if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone)
{
    [[VHeaderView sharedVHeaderView] viewWithCommonHeaderOnView1:self.view];
}
else
{
    [[VHeaderView_iPad sharedVHeaderView_iPad] viewWithCommonHeaderOnView1:self.view];

}

[splitViewController.view setFrame:CGRectMake(0,48, 768, 1024)];
  // [self.view removeFromSuperview];
//self.view.frame=CGRectMake(0,100, 768, 1024);
[self.view addSubview:splitViewController.view];


}

试试这个。为我工作。确保已分配导航 Controller 。

-(void)viewWillAppear:(BOOL)animated
{
    [super viewWillAppear:animated];
    [self.navigationController setNavigationBarHidden:YES];  
}

-(void)viewWillDisappear:(BOOL)animated
{
    [super viewWillDisappear:animated];

    [self.navigationController setNavigationBarHidden:NO]; 
}
