在横向模式下关闭视频后状态栏变为渐变 [英] status bar becomes gradient after closing video in landscape mode

问题描述

iOS 6正在发生以下情况。

Below is happening with iOS 6.

我正在播放可以在potrait或横向模式下播放的视频。按下视频的完成按钮后，我将以编程方式将屏幕设置为potrait模式。

I am playing video which can be played in potrait or landscape mode. Once video's Done button is pressed I am making screen to potrait mode programmatically.

问题是当我打开应用程序时，我有黑色状态栏。

The problem is when I open app, I have black status bar.

当我只播放视频作为potrait时，我仍然会看到如下所示的黑色状态栏。

When I play video as potrait only, I still see black status bar as shown below.

现在我播放视频并在播放完毕后转换旋转然后单击完成按钮，我在potrait模式下制作应用程序。 但现在我的状态栏变为浅黑色（可能是BlackTransculent）。

Now when I play video and shift rotation after after playback is done and click Done button, I make app in potrait mode. BUT now my status bar is changed to light black (maybe BlackTransculent).

如果你看到，我看到一些黑色留给了时间 即可。

Also if you see, I see something black left to the time.

知道出了什么问题吗？这实际上让我发疯。

以下是我正在使用的代码。

Below is the code I am using.

在viewcontroller.m中

In viewcontroller.m

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return (interfaceOrientation == UIInterfaceOrientationPortrait);
}

- (NSUInteger)supportedInterfaceOrientations
{
    return UIInterfaceOrientationMaskPortrait;
}

- (BOOL)shouldAutorotate
{
    return NO;
}

在CustomNavigation.m

In CustomNavigation.m

- (BOOL)shouldAutorotate
{
    return [self.visibleViewController shouldAutorotate];
}


- (NSUInteger)supportedInterfaceOrientations
{
    if (![[self.viewControllers lastObject] isKindOfClass:NSClassFromString(@"ViewController")])
    {
        return UIInterfaceOrientationMaskAllButUpsideDown;
    }
    else
    {
        return [self.topViewController supportedInterfaceOrientations];
    }
}

注意：

我不再使用下面的代码。

I am not using below code anymore.

[[UIDevice currentDevice] performSelector:NSSelectorFromString(@"setOrientation:") withObject:(id)UIInterfaceOrientationPortrait];

此问题仍然存在......

still this problem persist...

推荐答案

这很奇怪......

It's weird...

经过进一步调查后，我注意到当以横向模式播放视频时，状态栏会变为透明状态。

After further investigation, I noticed that when video is played in landscape mode, status bar is changed to transculent.

我尝试了什么以编程方式完成视频完成播放后，将状态栏设置回黑色 [[UIApplication sharedApplication] setStatusBarStyle：UIStatusBarStyleBlackOpaque]; ，但是这也不起作用。

What I tried programmatically is after video is done with playing, set status bar back to black [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];, BUT that was not also working.

所以我所做的就是当用户点回按钮时，我将其设置为黑色并且它正在工作。不确定是什么问题。

So what I did is when user hit back button, I set it to black and there it was working. Not sure what is the problem.

- (IBAction)takeMeBackAction:(id)sender {
    //    [self takeMeDownAction:nil];

    if (IS_DEVICE_RUNNING_IOS_6_OR_BELOW()) {
        [[UIApplication sharedApplication] setStatusBarStyle: UIStatusBarStyleBlackOpaque];
    }
}
