尝试发布 iOS 应用程序时出现黑屏问题答案

【问题标题】：Blank Screen Problem when trying to publish iOS App尝试发布 iOS 应用程序时出现黑屏问题

【问题描述】：

我们在发布应用时遇到了一些问题。首先在调试模式下，它适用于所有模拟器，但在发布期间，它并非一直有效。我们在 iPad 上遇到了黑屏问题。我们在 iPhone（物理设备）上也遇到了这个问题，但在 flutter clean 和 flutter build iOS -release 之后它工作了。然后我们在 XCode 中没有选择“compress the app”就将应用程序归档。您能否告诉我们您是否在 iPad 上遇到过这种“黑屏问题”？我们非常感谢任何建议。谢谢！

我们使用权限来通知和定位。我们在flutter pubspec中使用了以下包：

- cupertino_icons: ^0.1.2

- rxdart: ^0.18.0

- http: ^0.12.0+1

- firebase_database: ^2.0.2

- datetime_picker_formfield: ^0.1.8

- flutter_launcher_icons: ^0.7.0

- firebase_messaging: ^2.0.0

- firebase_crashlytics: ^0.0.4+2

if (geolocationStatus == GeolocationStatus.unknown)
      Map<PermissionGroup, PermissionStatus> permissions =
          await PermissionHandler()
              .requestPermissions([PermissionGroup.location,PermissionGroup.locationAlways, PermissionGroup.locationWhenInUse]);

void iOS_Permission() {
    firebaseMessaging.requestNotificationPermissions(
        IosNotificationSettings(sound: true, badge: true, alert: true)
    );
    firebaseMessaging.onIosSettingsRegistered
        .listen((IosNotificationSettings settings) {
    });
  }

我解决了这个问题。您需要在 Info.plist 中添加：

<key>UIRequiredDeviceCapabilities</key>
    <array>
        <string>gps</string>
        <string>location-services</string>
    </array>
