facebook fbDidLogin外面appdelegate [英] facebook fbDidLogin outside appdelegate

问题描述

我已经阅读了许多关于Facebook登录的问题，但直到我没有成功解决我的问题。我已经做了几个应用程序到目前为止，但我从来没有搞过appDelegate之前。

事情是，我想调用我的类别中的fbDidLogin方法其他而不是委托。

到目前为止，fbDidLogin正在appDelegate中被调用，但是我希望能够在登录发生后更改视图并请求用户信息。 / p>

我的代码到目前为止：
AppDelegate：

  （BOOL）应用程序：（UIApplication *）应用程序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] 
&&&&（&）;默认值为ObjectForKey：@FBExpirationDateKey]）{
 facebook.accessToken = [defaults objectForKey：@FBAccessTokenKey ]; 
 facebook.expirationDate = [defaults objectForKey：@FBExpirationDateKey]; 
} 
 
返回YES; 
} 
 
  - （BOOL）应用程序：（UIApplication *）应用程序openURL：（NSURL *）url sourceApplication：（NSString *）sourceApplication注释：（id）注释
 {
 return [facebook handleOpenURL：url]; 
} 
 
  - （BOOL）应用程序：（UIApplication *）应用程序handleOpenURL：（NSURL *）url 
 {
 return [facebook handleOpenURL：url]; 
} 
 
 //这个被正确调用
  - （void）fbDidLogin {
 NSLog（@[DELEGATE] Deu login！）; 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 [defaults setObject：[facebook accessToken] forKey：@FBAccessTokenKey]; 
 [defaults setObject：[facebook expirationDate] forKey：@FBExpirationDateKey]; 
 [默认同步]; 
} 
  

我自己的课程与Facebook登录按钮：

   - （void）loginFacebook {
 
 if（！[facebook isSessionValid]）{
 NSLog（@[LOGIN ] Facebook会话无效）; 
 NSArray * permissions = [[NSArray alloc] initWithObjects：
 @email，
 @user_birthday，
 nil]; 
 [facebook authorize：permissions]; 
 [权限释放]; 
} else {
 NSLog（@[LOGIN] Facebook会话有效）; 
 [facebook requestWithGraphPath：@meandDelegate：self]; 
} 
} 
 //我想要这个工作，所以我可以在它的末尾要求用户信息
  - （void）fbDidLogin {
 NSLog（ @[LOGIN] [FB] Deu login！）; 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 [defaults setObject：[facebook accessToken] forKey：@FBAccessTokenKey]; 
 [defaults setObject：[facebook expirationDate] forKey：@FBExpirationDateKey]; 
 [默认同步]; 
 [facebook requestWithGraphPath：@meandDelegate：self]; 
} 
  

我很抱歉，如果这不清楚，如果您需要更多信息让我知道

解决方案

您可以从App代理发布通知，如下所示：

   - （void）fbDidLogin {
 [[NSNotificationCenter defaultCenter] postNotificationName：@FBDidLoginCalledobject：nil]; 
} 
  

然后在您的其他类中：

   - （void）loginFacebook {
 
 if（！[facebook isSessionValid]）{
 [[NSNotificationCenter defaultCenter] addObserver：self选择器：@selector（fbDidLoginNotificationFired）名称：@FBDidLoginCalled对象：nil] 
 NSLog（@[LOGIN] Facebook会话无效）; 
 NSArray * permissions = [[NSArray alloc] initWithObjects：
 @email，
 @user_birthday，
 nil]; 
 [facebook authorize：permissions]; 
 [权限释放]; 
} else {
 NSLog（@[LOGIN] Facebook会话有效）; 
 [facebook requestWithGraphPath：@meandDelegate：self]; 
} 
} 
 //我想要这个工作，所以我可以在它的结尾要求用户信息
  - （void）fbDidLoginNotificationFired {
 [[ NSNotificationCenter defaultCenter] removeObserver：self name：@FBDidLoginCalledobject：nil]; 
 
 NSLog（@[LOGIN] [FB] Deu login！）; 
 NSUserDefaults * defaults = [NSUserDefaults standardUserDefaults]; 
 [defaults setObject：[facebook accessToken] forKey：@FBAccessTokenKey]; 
 [defaults setObject：[facebook expirationDate] forKey：@FBExpirationDateKey]; 
 [默认同步]; 
 [facebook requestWithGraphPath：@meandDelegate：self]; 
} 
  

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.

解决方案

You can post a notification from the App Delegate like so:

- (void)fbDidLogin {
    [[NSNotificationCenter defaultCenter] postNotificationName:@"FBDidLoginCalled" object:nil];
}

And then in your other class:

- (void)loginFacebook {

    if (![facebook isSessionValid]) {
        [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(fbDidLoginNotificationFired) name:@"FBDidLoginCalled" object:nil]
        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)fbDidLoginNotificationFired {
    [[NSNotificationCenter defaultCenter] removeObserver:self name:@"FBDidLoginCalled" object:nil];

    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];
}
