iOS 6中的iOS隐藏标签栏创建黑条（iOS 6的修复打破了iOS 7！） [英] iOS Hiding tab bar in iOS 6 creates black bar (fix for iOS 6 breaks iOS 7!)

问题描述

我有一个标签式应用程序，在一个标签中有一个 UIWebView 。当我将设备旋转到横向时，我在隐藏状态和标签栏的同时全屏显示 UIWebView 。

我已经在iOS 6中运行了 - 最初在旋转和隐藏标签栏时会在标签栏上留下一个黑色空间，所以 fHeight 代码修复了这个问题。但是，在iOS 6上它运行得很好，但现在它确实造成了iOS 6的黑条问题!!有关解决方法的任何想法吗？

请参阅下面的我的编辑

 if（toInterfaceOrientation == UIInterfaceOrientationLandscapeLeft || toInterfaceOrientation == UIInterfaceOrientationLandscapeRight）{

 [[UIApplication sharedApplication] setStatusBarHidden：TRUE withAnimation：UIStatusBarAnimationSlide]; 
} 
 else 
 {
 [self showTabBar：self.tabBarController]; 
 [[UIApplication sharedApplication] setStatusBarHidden：FALSE withAnimation：UIStatusBarAnimationSlide]; 
}

<我已经尝试过使用这个但我不确定如何正确传递视图 - 我已经尝试了 self.view 和webView以及其他但我可以'让它在iOS 6和7上都能运行！任何想法都会非常有用！如果您需要更多信息，请告诉我

   - （void）setTabBarHidden：（BOOL）隐藏视图：（UIView *）查看动画：（BOOL）动画
 {
 if（self.tabBar.hidden == hidden）
 return; 
 
 CGRect screenRect = [[UIScreen mainScreen] bounds]; 
浮动高度= 0.0f; 
 
 if（UIDeviceOrientationIsLandscape（[UIApplication sharedApplication] .statusBarOrientation））
 {
 height = screenRect.size.width; 
} 
其他
 {
 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完成）= ^（BOOL完成）{
 self.tabBar.hidden = hidden; 
}; 
 
 if（animated）
 {
 [UIView animateWithDuration：0.25f animations：workerBlock completion：completionBlock]; 
} 
 else 
 {
 workerBlock（）; 
 completionBlock（YES）; 
} 
} 
  

解决方案

我最终得到了这个工作，但它花了一段时间。它源于我的原始代码和一些JRG-Developers工作的混合。

   - （void）didRotateFromInterfaceOrientation：（UIInterfaceOrientation） fromInterfaceOrientation {
 
 BOOL toLandscape = UIDeviceOrientationIsLandscape（[UIApplication sharedApplication] .statusBarOrientation）; 
 
 CGRect screenRect = [[UIScreen mainScreen] bounds]; 
 
 void（^ workerBlock）（）= ^（）{
 
 
 [[UIApplication sharedApplication] setStatusBarHidden：toLandscape withAnimation：UIStatusBarAnimationSlide]; 
 
浮动高度= 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），
宽度，
高度）; 
 
 [self moveTabBarToPosition：height]; 
}; 
 
 [UIView animateWithDuration：0.25f animations：workerBlock]; 
} 
 //在屏幕上移动标签栏及其子视图，使顶部位于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]; 
} 
} 
} 
  

在我的情况下这是我的webview但理论上你可以给它任何视图。适用于iOS 6和7

I've got a tabbed application and in one tab there is a UIWebView. When I rotate the device to landscape I've made the UIWebView full screen while hiding the status and tab bar.

I've got it working in iOS 6 - originally when rotating and hiding the tab bar it would leave a black space where the tab bar was, so the fHeight code fixes this. However, on iOS 6 it worked perfectly, but now it actually creates the black bar problem iOS 6 was having!! Any ideas for a workaround to this?

Please see my edit below this

- (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];
}

//Edit

I've tried using this but I'm not sure how to pass in the view properly - I've tried self.view and webView and others but I can't get it to work on both iOS 6 and 7! Any kind of idea at all would be really helpful! Let me know if you need more info

- (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);
    }
}

解决方案

I eventually got this working, but it took a while. It stemmed from a mixture of my original code and some of JRG-Developers work.

- (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];
        }
    }
}

In my case this is for my webview but theoretically you can give it any view. Works in iOS 6 and 7
