SIGABRT：对象引用未设置到对象 SetStatusBarColor Xamarin 的实例 iOS

Question

我在将应用程序提交到 AppStore 时遇到崩溃 SIGABRT: Object reference not set to an instance of an object。我检查了 Apple 的日志文件。此时注意到：

protected override void OnAppearing()
{
    base.OnAppearing();

    var statusbar = DependencyService.Get<IStatusBarPlatformSpecific>();
    statusbar.SetStatusBarColor(Color.FromHex("f1f1f1"));
}

IStatusBarPlatformSpecific.cs

public interface IStatusBarPlatformSpecific
{
    void SetStatusBarColor(Color color);
}

受影响最大OS：15.4.1

期待大家的解答。谢谢

您应该得到如下 statusbar：

    UIView statusBar = new UIView(UIApplication.SharedApplication.KeyWindow.WindowScene.StatusBarManager.StatusBarFrame);
           

            if(statusBar == null)
            {
                //throw a meaningful exception or give some useful feedback!
                return;
            }
            else
            {
                statusBar.BackgroundColor = color.AddLuminosity(0).ToUIColor();
                UIApplication.SharedApplication.KeyWindow.AddSubview(statusBar);
            }
