旋转设备 iPhone 时隐藏 UITabBar

发布于 2024-08-22 04:44:04 字数 244 浏览 4 评论 0原文

有人在旋转设备时成功隐藏了 UITabbar 吗？

我在 UItabbar 控制器中有一个视图可以旋转（因此有效地旋转一个选项卡）

当发生这种情况时，我希望选项卡栏消失......但似乎没有任何效果！

要么选项卡栏仍然可见

，要么随视图一起消失

，要么选项卡栏消失并且视图不再旋转！

因此，如果有人成功完成了这项任务，我们将不胜感激！

谢谢

汤姆

抱歉回复晚了，

我设法旋转并隐藏了标签栏。

首先是子类化 UITabBarController 的情况，并包含此方法：

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    //This allows us to get the rotation calls from any view in the tab bar
    // 

    return [self.selectedViewController shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation];
}

然后您可以仅从所需的视图控制器进行旋转。

隐藏选项卡栏：

获取应用程序委托和选项卡栏控制器的引用，然后将选项卡栏设置为隐藏：

MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
UIView *tabBar = [delegate.tabBarController.view.subviews objectAtIndex:1];
tabBar.hidden = TRUE;

希望这有帮助！

Sorry for the late reply pk

I managed to rotate and hide the tab bar.

First it was a case of subclassing the UITabBarController, and including this method:

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

    //This allows us to get the rotation calls from any view in the tab bar
    // 

    return [self.selectedViewController shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation];
}

And then you can rotate from only the required view controllers.

To hide the tab bar:

Get reference to the app delegate and the Tab bar controller, and then set the tab bar to hidden:

MyAppDelegate *delegate = (MyAppDelegate *)[[UIApplication sharedApplication] delegate];
UIView *tabBar = [delegate.tabBarController.view.subviews objectAtIndex:1];
tabBar.hidden = TRUE;

Hope this helps!

您是否尝试在视图控制器中的 UIDeviceOrientationDidChangeNotification 通知上添加观察者，并在此回调上执行“Hidden = true 或 false”？

我使用 MonoTouch 框架通过以下 C# 代码成功完成了此任务。

void Initialize ()
{
    NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated);          
}

private void DeviceRotated(NSNotification notification)
{
    if ( notification.Name.Equals("UIDeviceOrientationDidChangeNotification") )
    {
        Console.WriteLine(UIDevice.CurrentDevice.Orientation.ToString());
        if ( UIDevice.CurrentDevice.Orientation != UIDeviceOrientation.Portrait ) 
        {
            tabBar.Hidden = true;
            //Plus some additional logic.
        }
        else
        {
            tabBar.Hidden = false;
        }
    }
}

Have you tried to add an observer on the UIDeviceOrientationDidChangeNotification notification in view controller, and do the "Hidden = true or false" on this callback?

I successfully accomplished this with the following C# code using the MonoTouch framework.

void Initialize ()
{
    NSNotificationCenter.DefaultCenter.AddObserver("UIDeviceOrientationDidChangeNotification", DeviceRotated);          
}

private void DeviceRotated(NSNotification notification)
{
    if ( notification.Name.Equals("UIDeviceOrientationDidChangeNotification") )
    {
        Console.WriteLine(UIDevice.CurrentDevice.Orientation.ToString());
        if ( UIDevice.CurrentDevice.Orientation != UIDeviceOrientation.Portrait ) 
        {
            tabBar.Hidden = true;
            //Plus some additional logic.
        }
        else
        {
            tabBar.Hidden = false;
        }
    }
}
