facebook fbDidLogin appdelegate外面(facebook fbDidLogin outside appdelegate)

 我已经阅读了很多关于facebook登录的问题，但直到没有成功解决我的问题。 到目前为止我已经制作了一些应用程序，但我之前从未搞过appDelegate。 
 
 问题是我想调用除了委托之外的类内部的fbDidLogin方法。 
 
 到目前为止，fbDidLogin正在appDelegate中调用，但我希望能够在登录发生后更改视图并询问用户信息。 
 
 我的代码到目前为止：AppDelegate： 
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    facebook = [[Facebook alloc] initWithAppId:SHKCONFIG(facebookAppId) andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
    return [facebook handleOpenURL:url];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
{
    return [facebook handleOpenURL:url];
}

// This one is called correctly
- (void)fbDidLogin {
    NSLog(@"[DELEGATE] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
}
 
 我自己上课的facebook登录按钮： 
 
- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        NSLog(@"[LOGIN] Facebook session invalid");
        NSArray * permissions =  [[NSArray alloc] initWithObjects:
                                 @"email",
                                 @"user_birthday",
                                 nil];
        [facebook authorize:permissions];   
        [permissions release];
    } else {
        NSLog(@"[LOGIN] Facebook session valid");
        [facebook requestWithGraphPath:@"me" andDelegate:self];
    }
}
// I want this one to work so I can ask for user info at the end of it
- (void)fbDidLogin {
    NSLog(@"[LOGIN][FB] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}
 
 对不起，如果不清楚，如果您需要更多信息，请告诉我。 

I have read many questions about the facebook login but until not I didnt succeed on solving my problem. I have made a few apps so far but I have never messed with the appDelegate before.
 
The thing is that I want to call the fbDidLogin method that is inside my class other than delegate.
 
Until now, fbDidLogin is being called in the appDelegate, but I want to be able to change the view and ask for user info after the login happens.
 
My code so far: AppDelegate:
 
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    self.window.rootViewController = self.tabBarController;
    [self.window makeKeyAndVisible];

    facebook = [[Facebook alloc] initWithAppId:SHKCONFIG(facebookAppId) andDelegate:self];
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    if ([defaults objectForKey:@"FBAccessTokenKey"] 
        && [defaults objectForKey:@"FBExpirationDateKey"]) {
        facebook.accessToken = [defaults objectForKey:@"FBAccessTokenKey"];
        facebook.expirationDate = [defaults objectForKey:@"FBExpirationDateKey"];
    }

    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{
    return [facebook handleOpenURL:url];
}

- (BOOL)application:(UIApplication *)application handleOpenURL:(NSURL *)url 
{
    return [facebook handleOpenURL:url];
}

// This one is called correctly
- (void)fbDidLogin {
    NSLog(@"[DELEGATE] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
}
 
My own class with the facebook login button:
 
- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        NSLog(@"[LOGIN] Facebook session invalid");
        NSArray * permissions =  [[NSArray alloc] initWithObjects:
                                 @"email",
                                 @"user_birthday",
                                 nil];
        [facebook authorize:permissions];   
        [permissions release];
    } else {
        NSLog(@"[LOGIN] Facebook session valid");
        [facebook requestWithGraphPath:@"me" andDelegate:self];
    }
}
// I want this one to work so I can ask for user info at the end of it
- (void)fbDidLogin {
    NSLog(@"[LOGIN][FB] Deu login!");
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject:[facebook accessToken] forKey:@"FBAccessTokenKey"];
    [defaults setObject:[facebook expirationDate] forKey:@"FBExpirationDateKey"];
    [defaults synchronize];
    [facebook requestWithGraphPath:@"me" andDelegate:self];
}
 
I sorry if this is not clear, if you need more info let me know.
