タブ付きのアプリケーションがあり、1 つのタブに UIWebView があります。デバイスを横向きに回転させると、この UIWebView をステータスバーとタブバーの上に全画面表示にしたいと思います。

//編集

わかりましたので、iOS 6で動作するようになりました.もともとタブバーを回転させて非表示にすると、タブバーがあった場所に黒いスペースが残るため、fHeightコードはこれを修正します. ただし、iOS 6 では完全に機能しましたが、実際には iOS 6 で発生していた黒いバーの問題が発生します!! これに対する回避策のアイデアはありますか?

- (void)willRotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation duration:(NSTimeInterval)duration;
{
    if(toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight) {
        [self hideTabBar:self.tabBarController];
        [[UIApplication sharedApplication] setStatusBarHidden:TRUE withAnimation:UIStatusBarAnimationSlide];
    }
    else
    {
        [self showTabBar:self.tabBarController];
        [[UIApplication sharedApplication] setStatusBarHidden:FALSE withAnimation:UIStatusBarAnimationSlide];
    }
}

- (void) hideTabBar:(UITabBarController *) tabbarcontroller
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    float fHeight = screenRect.size.height;
    if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
    {
        fHeight = screenRect.size.width;
    }

    for(UIView *view in self.tabBarController.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
        }
        else
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
            view.backgroundColor = [UIColor blackColor];
        }
    }
    [UIView commitAnimations];
}

- (void) showTabBar:(UITabBarController *) tabbarcontroller
{
    CGRect screenRect = [[UIScreen mainScreen] bounds];
    float fHeight = screenRect.size.height - 49.0;

    if(  UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation) )
    {
        fHeight = screenRect.size.width - 49.0;
    }

    [UIView beginAnimations:nil context:NULL];
    [UIView setAnimationDuration:0.5];
    for(UIView *view in tabbarcontroller.view.subviews)
    {
        if([view isKindOfClass:[UITabBar class]])
        {
            [view setFrame:CGRectMake(view.frame.origin.x, fHeight, view.frame.size.width, view.frame.size.height)];
        }
        else
        {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, fHeight)];
        }
    }
    [UIView commitAnimations];
}

これを使用してみましたが、どのビューを渡す必要があるかわかりませんか? iOS 6および7で動作するはずです

- (void)setTabBarHidden:(BOOL)hidden view:(UIView *)view animated:(BOOL)animated
{
    if (self.tabBar.hidden == hidden)
        return;

    CGRect screenRect = [[UIScreen mainScreen] bounds];
    float height = 0.0f;

    if(UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation))
    {
        height = screenRect.size.width;
    }
    else
    {
        height = screenRect.size.height;
    }

    if (!hidden)
    {
        height -= CGRectGetHeight(self.tabBar.frame);
    }

    void (^workerBlock)() = ^() {

        self.tabBar.frame = CGRectMake(CGRectGetMinX(self.tabBar.frame), height, CGRectGetWidth(self.tabBar.frame), CGRectGetHeight(self.tabBar.frame));
        view.frame = CGRectMake(CGRectGetMinX(view.frame), CGRectGetMinY(view.frame), CGRectGetWidth(view.frame), height);
    };

    void (^completionBlock)(BOOL finished) = ^(BOOL finished) {
        self.tabBar.hidden = hidden;
    };

    if (animated)
    {
        [UIView animateWithDuration:0.25f animations:workerBlock completion:completionBlock];
    }
    else
    {
        workerBlock();
        completionBlock(YES);
    }
}

試す...

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

-(void)viewWillDisappear:(BOOL)animated
{
    [self.navigationController setNavigationBarHidden:NO animated:animated];
    [self setHidesBottomBarWhenPushed:NO];
    [super viewWillDisapper:animated];
}

少し前にこれを機能させましたが、2つの同様の質問があったため、回答を投稿するのを忘れていました! iOS 6 および 7 で動作

- (void)didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation {

    BOOL toLandscape = UIDeviceOrientationIsLandscape([UIApplication sharedApplication].statusBarOrientation);

    CGRect screenRect = [[UIScreen mainScreen] bounds];

    void (^workerBlock)() = ^() {


        [[UIApplication sharedApplication] setStatusBarHidden:toLandscape withAnimation:UIStatusBarAnimationSlide];

        float height = toLandscape ? screenRect.size.width : screenRect.size.height - CGRectGetHeight(self.tabBarController.tabBar.frame);

        float width = toLandscape ? screenRect.size.height : screenRect.size.width;

        webView.frame = CGRectMake(CGRectGetMinX(webView.frame),
                               CGRectGetMinY(webView.frame),
                               width,
                               height);

        [self moveTabBarToPosition:height];
    };

    [UIView animateWithDuration:0.25f animations:workerBlock];
}
//Moving the tab bar and its subviews offscreen so that top is at position y
-(void)moveTabBarToPosition:(int)y {
    self.tabBarController.tabBar.frame = CGRectMake(self.tabBarController.tabBar.frame.origin.x, y, self.tabBarController.tabBar.frame.size.width, self.tabBarController.tabBar.frame.size.height);

    for(UIView *view in self.tabBarController.view.subviews) {
        if ([view isKindOfClass:[UITabBar class]]) {
            [view setFrame:CGRectMake(view.frame.origin.x, y, view.frame.size.width, view.frame.size.height)];
        } else {
            [view setFrame:CGRectMake(view.frame.origin.x, view.frame.origin.y, view.frame.size.width, y)];
            view.backgroundColor = [UIColor blackColor];
        }
    }
}

私の場合、これは私の webview 用ですが、理論的には任意のビューを与えることができます。iOS 6 および 7 で動作
