FBSDK：无法读取属性loginwithreadpermissions的undefined

我正在使用FBSDK设置一个React Native项目用于login目的。

以下是我迄今为止所做的：

1. 我运行npm install react-native-fbsdk --save
2. 我运行了react-native link
3. 我遵循这里提到的每一步： https ： //developers.facebook.com/docs/facebook-login/ios/
4. 我再次检查使用此video： https ： //www.youtube.com/watch？v = rAXVKapP5cM

不过，我仍然得到这个红色的屏幕错误：

Cannot read property logInWithReadPermissions of undefined在FBLoginManager.js第77行（ https://github.com/facebook/react-native-fbsdk/blob/master/js/FBLoginManager.js ） Cannot read property logInWithReadPermissions of undefined

这是我的AppDelegate.m内容：

 #import "AppDelegate.h" #import <FBSDKCoreKit/FBSDKCoreKit.h> #import <React/RCTBundleURLProvider.h> #import <React/RCTRootView.h> @implementation AppDelegate - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { NSURL *jsCodeLocation; jsCodeLocation = [[RCTBundleURLProvider sharedSettings] jsBundleURLForBundleRoot:@"index.ios" fallbackResource:nil]; RCTRootView *rootView = [[RCTRootView alloc] initWithBundleURL:jsCodeLocation moduleName:@"PegaseBuzzApp" initialProperties:nil launchOptions:launchOptions]; rootView.backgroundColor = [[UIColor alloc] initWithRed:1.0f green:1.0f blue:1.0f alpha:1]; [[FBSDKApplicationDelegate sharedInstance] application:application didFinishLaunchingWithOptions:launchOptions]; self.window = [[UIWindow alloc] initWithFrame:[UIScreen mainScreen].bounds]; UIViewController *rootViewController = [UIViewController new]; rootViewController.view = rootView; self.window.rootViewController = rootViewController; [self.window makeKeyAndVisible]; return YES; } - (void)applicationDidBecomeActive:(UIApplication *)application { [FBSDKAppEvents activateApp]; } - (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation { return [[FBSDKApplicationDelegate sharedInstance] application:application openURL:url sourceApplication:sourceApplication annotation:annotation]; } @end 

这是我的链接框架和二进制文件：

编辑：在我的项目上：

 const FBSDK = require('react-native-fbsdk'); const { LoginManager, } = FBSDK; 

加：

 _onFBButtonPress () { LoginManager.logInWithReadPermissions(['public_profile']).then( function(result) { if (result.isCancelled) { alert('Login cancelled'); } else { alert('Login success with permissions: ' +result.grantedPermissions.toString()); } }, function(error) { alert('Login fail with error: ' + error); } ); } 

和：

 <Button onPress={() => this._onFBButtonPress()} buttonStyle={'buttonFb'} labelStyle={'buttonFbText'} label={I18n.t('Login.btnConnectFB')}></Button> 

我错过了什么？

我刚刚解决了同样的错误。 出于某种原因，“react-native link react-native-fbsdk”已经为Android完成，而不是ios。

rnpm-install info Android模块react-native-fbsdk已链接rnpm-install info链接react-native-fbsdk ios依赖关系rnpm -install信息iOS模块react-native-fbsdk已成功链接

尝试重新运行，并确保您正在与libRCTFBSDK.a链接
