【解决方案1】：

不确定您使用的是哪个 iOS 版本。我在 iOS 8.3 中遇到过这种情况，这就是我在您的 viewWillAppear 方法中解决它的方法：

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

添加上面的代码，看看问题是否解决。

【解决方案2】：

你的问题是这段代码：

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

当导航弹出或推送，或者显示或关闭视图控制器时，将调用此函数。如果应该这样检查

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