使用未声明的标识符'RNFirebaseNotifications''RNFirebaseMessaging'

问题描述

fb登录SDK正常运行，但现在开始出现这些错误。

我的进口是这样的

#import "AppDelegate.h"

#import <React/RCTBridge.h>
#import <React/RCTBundleURLProvider.h>
#import <React/RCTRootView.h>
#import <GoogleMaps/GoogleMaps.h>
#import <Firebase.h>
#ifdef FB_SONARKIT_ENABLED
#import <FlipperKit/FlipperClient.h>
#import <FlipperKitLayoutPlugin/FlipperKitLayoutPlugin.h>
#import <FlipperKitUserDefaultsPlugin/FKUserDefaultsPlugin.h>
#import <FlipperKitNetworkPlugin/FlipperKitNetworkPlugin.h>
#import <SKIOSNetworkPlugin/SKIOSNetworkAdapter.h>
#import <FlipperKitReactPlugin/FlipperKitReactPlugin.h>
#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <RNFirebaseNotifications.h>
#import <RNFirebaseMessaging.h>

请帮助解决该问题。谢谢

解决方法

我今天有同样的问题。要解决此问题，请将class MainViewModel : ViewModel() { private val _permissionGranted = MutableLiveData(false) val permissionGranted = _permissionGranted fun onPermissionGranted() = _permissionGranted.postValue(true) // ... } 语句移到class MainActivity : AppCompatActivity() { private val mainViewModel by viewModels<MainViewModel> override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) setContent { val permissionGranted = mainViewModel.permissionGranted.observeAsState() if (permissionGranted) { // logic to show your map } else { // logic to ask for permission } } } override fun onRequestPermissionsResult(requestCode: Int,permissions: Array<String>,grantResults: IntArray) { // check if it's your request mainViewModel.onPremissionGranted() } // ... } 块之外。
