iPhone上的Facebook SDK登錄問題

Question

我正在嘗試將Facebook SDK集成到我的應用程序中，並且可以在我的模擬器中完美運行。 當我將其安裝到iPhone上並嘗試運行它時，它會向我顯示一條警報，指出“ myapp需要訪問您的個人資料，好友列表等”，並且當我選擇允許它不執行任何操作時-它需要這些權限。

我已經在iPhone上安裝了Facebook應用程序，嘗試了多次注銷並重新登錄，但是沒有使用。

但是，當我進入設置並刪除Facebook詳細信息時，它可以正常運行：

我怎樣才能解決這個問題？

Answer 1

我使用以下方式為我工作：

-(void)openFacebookAuthentication
{
    NSArray *permission = [NSArray arrayWithObjects:kFBEmailPermission,kFBUserPhotosPermission, nil];

    FBSession *session = [[FBSession alloc] initWithPermissions:permission];

    [FBSession setActiveSession: [[FBSession alloc] initWithPermissions:permission] ];

    [[FBSession activeSession] openWithBehavior:FBSessionLoginBehaviorForcingWebView completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {

        switch (status) {
            case FBSessionStateOpen:
                [self getMyData];
                break;
            case FBSessionStateClosedLoginFailed: {
                // prefer to keep decls near to their use
                // unpack the error code and reason in order to compute cancel bool
                NSString *errorCode = [[error userInfo] objectForKey:FBErrorLoginFailedOriginalErrorCode];
                NSString *errorReason = [[error userInfo] objectForKey:FBErrorLoginFailedReason];
                BOOL userDidCancel = !errorCode && (!errorReason || [errorReason isEqualToString:FBErrorLoginFailedReasonInlineCancelledValue]);


                if(error.code == 2 && ![errorReason isEqualToString:@"com.facebook.sdk:UserLoginCancelled"]) {
                    UIAlertView *errorMessage = [[UIAlertView alloc] initWithTitle:kFBAlertTitle
                                                                           message:kFBAuthenticationErrorMessage
                                                                           delegate:nil
                                                                           cancelButtonTitle:kOk
                                                                           otherButtonTitles:nil];
                    [errorMessage performSelectorOnMainThread:@selector(show) withObject:nil waitUntilDone:YES];
                    errorMessage = nil;
                    }
                }
                break;
                // presently extension, log-out and invalidation are being implemented in the Facebook class
            default:
                break; // so we do nothing in response to those state transitions
        }
    }];
    permission = nil;
}

請記住將您的應用程序添加到Facebook開發人員/應用程序中！！

如果沒有，您將無法與他們的服務器進行交互...

好吧，我知道出了什么問題。 讓我知道您所做的一切都是正確的，但是想要的結果還需要其他內容。

嘗試這個 -

首先，在您的應用程序委托中實現所有facebook sdk委托方法。

- (IBAction)loginWithFacebookButtonTapped:(id)sender
{
    IntubeAppDelegate *delegat = (IntubeAppDelegate*)[[UIApplication sharedApplication] delegate];
    [delegat doLoginAndSwitch];
}

現在，在您的appDelegate中-

-(void) doLoginAndSwitch
{      
    [self openSessionWithAllowLoginUI:YES];
}

- (BOOL)openSessionWithAllowLoginUI:(BOOL)allowLoginUI
{
    NSArray *permissions = [NSArray arrayWithObjects:@"email", nil]; 
    return [FBSession openActiveSessionWithPublishPermissions:permissions
                                          defaultAudience:FBSessionDefaultAudienceFriends
                                             allowLoginUI:YES
                                        completionHandler:^(FBSession *session, FBSessionState state, NSError *error) {

                                            [self sessionStateChanged:session
                                                                state:state
                                                                error:error];

                                        }];
}

-(BOOL)openSessionWithAllowPublishStreamPermission:(BOOL)allowLoginUI
{
    NSArray *permissions = [NSArray arrayWithObjects:@"publish_actions",@"publish_stream", nil];

    [[FBSession activeSession] requestNewPublishPermissions:permissions defaultAudience:FBSessionDefaultAudienceEveryone completionHandler:^(FBSession *session, NSError *error){
}];
    return YES;
}

- (void)sessionStateChanged:(FBSession *)session
                  state:(FBSessionState)state
                  error:(NSError *)error
{
    switch (state) {
        case FBSessionStateOpen:
            if(!error)
            {
              //  NSLog(@"FBSessionStateOpen :- logged in");

                [self openSessionWithAllowPublishStreamPermission:YES];

              // Your code
            }
     }    
} 

同樣要切換回您的應用程序-

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation 
{

    return [FBSession.activeSession handleOpenURL:url];
}

希望您現在能得到想要的。 :)
