iphone - ログイン時に FBConnect がアプリをクラッシュさせる

Question

アプリを FBConnect に接続しようとしていますが、毎回クラッシュします。以前の資格情報をすべて取得し、ログイン後にクラッシュします。ログインすると、アプリが開くように、これに接続する必要があります。

私のコードは

- (void)session:(FBSession*)session didLogin:(FBUID)uid {
    NSString* fql = [NSString stringWithFormat:
                 @"select uid,name from user where uid == %lld", self.usersession.uid];
    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
    self.post=YES;
    self.usersession =session;
    NSLog(@"User with id %lld logged in.", uid);
    [self getFacebookName];
}

session didloginログインに成功した後、アプリに入るためにコードを入力すると。それは同じことでクラッシュします...

- (void)session:(FBSession*)session didLogin:(FBUID)uid {


    NSString* fql = [NSString stringWithFormat:
                 @"select uid,name from user where uid == %lld", self.usersession.uid];
    NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];
    [[FBRequest requestWithDelegate:self] call:@"facebook.fql.query" params:params];
    self.post=YES;

    self.usersession =session;
    NSLog(@"User with id %lld logged in.", uid);


    AppDelegate *appdelegte =(AppDelegate*)[[UIApplication sharedApplication]delegate];

    [[[appdelegte navigationController] view]removeFromSuperview];

    [[appdelegte window]addSubview:[[appdelegte tabBarController]view]];

    [[appdelegte tabBarController]setSelectedIndex:0];


    [self getFacebookName];
}

- (void)getFacebookName {
NSString* fql = [NSString stringWithFormat:
                 @"select uid,name from user where uid == %lld", self.usersession.uid];
NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:@"query"];

self.post=YES;
}
