Ios 上传图像时隐藏状态栏

当我将图像从相机上传到imageview时，图像上传成功，但我的状态栏变为隐藏。我在iOS上比较新。请帮忙。任何我正在应用程序中设置的代理。他们隐藏了我的状态栏。任何帮助都会得到安抚

    [application setStatusBarStyle:UIStatusBarStyleLightContent];
       [[UIApplication sharedApplication] setStatusBarHidden:NO withAnimation:NO];

and i m setting in info.plist  

    View controller-based status bar appearance  NO
    -(IBAction)choosePicture:(id)sender
    {
     imagePicker=[[UIImagePickerController alloc]init];
        imagePicker.sourceType=UIImagePickerControllerSourceTypePhotoLibrary;
        imagePicker.delegate=self;
        [self presentViewController:imagePicker animated:YES completion:nil];


    }
    -(IBAction)takePicture:(id)sender
    {
      imagePicker=[[UIImagePickerController alloc]init];
        imagePicker.sourceType=UIImagePickerControllerSourceTypeCamera;
        imagePicker.delegate = self;

        [self presentViewController:imagePicker animated:YES completion:nil];
    }
    -(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
    {
        pickedImage=[info objectForKey:UIImagePickerControllerOriginalImage];

        [self performSelectorInBackground:@selector(saveImage:) withObject:nil];

        image.image=pickedImage;
        pickedImage  =  [self compressImage:pickedImage];


        pickedImageData=UIImageJPEGRepresentation(pickedImage,0.9);
                       [self dismissViewControllerAnimated:YES completion:nil];
    }
-(void)navigationController:(UINavigationController *)navigationController
     willShowViewController:(UIViewController *)viewController
                   animated:(BOOL)animated
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

-(BOOL)prefersStatusBarHidden   // also do this for iOS 8
{
    return YES;
}

不确定您正在使用哪个iOS版本。我在iOS 8.3中体验到了这一点，这就是我如何解决它的，在您的viewWillExample方法中：

    - (void)viewWillAppear:(BOOL)animated {
        [[UIApplication sharedApplication] setStatusBarHidden:NO];
    }

添加上述代码以查看问题是否已解决。

您的问题是以下代码：

-(void)navigationController:(UINavigationController *)navigationController
     willShowViewController:(UIViewController *)viewController
                   animated:(BOOL)animated
{
    [[UIApplication sharedApplication] setStatusBarHidden:YES];
}

当导航弹出或按下、显示或关闭viewcontroller时，将调用此函数。如果你应该这样检查

-(void)navigationController:(UINavigationController *)navigationController
     willShowViewController:(UIViewController *)viewController
                   animated:(BOOL)animated
{
    if ([viewController isKindOfClass:[UIImagePickerViewController class]])
    {
        [[UIApplication sharedApplication] setStatusBarHidden:YES];
    }
    else
    {
        [[UIApplication sharedApplication] setStatusBarHidden:NO];
    }
}

请添加您的代码。。不管你现在做了什么。
