隐藏和显示带有点击手势的导航栏

Question

可能的重复项：
点击时隐藏/显示导航和工具栏

这是我用来在其中一个视图中隐藏导航栏的空白。

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

如何点击屏幕隐藏和显示导航栏？

Answer 1

你希望这样吗？

- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationController.navigationBar.translucent = YES;
                             self.wantsFullScreenLayout = YES;
    UITapGestureRecognizer *tap = [[[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(hideShowNavigation)] autorelease];
    tap.numberOfTapsRequired = 1;
    [self.view addGestureRecognizer:tap];
}
- (void) hideShowNavigation
{
    [self.navigationController setNavigationBarHidden:!self.navigationController.navigationBarHidden];
}
