适用于iOS的Facebook SDK 3.6 for iOS错误2

Question

Facebook登录可以在iOS模拟器上正常运行，但不能在设备（iPhone 4）上运行。 至于它在模拟器上的工作，我认为facebookId，权限....设置都可以。

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];
}];

有什么帮助吗？ 谢谢

解决了！！！

我在FacebookSDK中检查了SessionLoginSample，并找到了解决方案。

我不得不将上面的代码更改为此：

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中添加了一个属性

@property (strong, nonatomic) FBSession *session;

并更改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];

}

现在工作正常:)
