適用於iOS的Facebook SDK 3.6 for iOS錯誤2

Question

Facebook登錄可以在iOS模擬器上正常運行，但不能在設備（iPhone 4）上運行。 至於它在模擬器上的工作，我認為facebookId，權限....設置都可以。

NSArray *permissions = [NSArray arrayWithObjects:@"email",nil];

[FBSession openActiveSessionWithReadPermissions:permissions allowLoginUI:YES completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
    [self sessionStateChanged:session state:status error:error];
}];

有什么幫助嗎？ 謝謝

解決了！！！

我在FacebookSDK中檢查了SessionLoginSample，並找到了解決方案。

我不得不將上面的代碼更改為此：

MyAppDelegate *appDelegate = [[UIApplication sharedApplication]delegate];
if (!appDelegate.session.isOpen || appDelegate.session.state != FBSessionStateCreated) {
    // Create a new, logged out session.
    appDelegate.session = [[FBSession alloc] init];
}

// if the session isn't open, let's open it now and present the login UX to the user
[appDelegate.session openWithCompletionHandler:^(FBSession *session,
                                                 FBSessionState status, 
                                                 NSError *error) {
    // and here we make sure to update our UX according to the new session state
    [self sessionStateChanged:session state:status error:error];
}];

我在MyAppDelegate.h中添加了一個屬性

@property (strong, nonatomic) FBSession *session;

並更改MyAppDelegate.m中的方法

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication: (NSString *)sourceApplication annotation:(id)annotation
{
//  return [FBSession.activeSession handleOpenURL:url];
return [FBAppCall handleOpenURL:url sourceApplication:sourceApplication withSession:self.session];

}

現在工作正常:)
