在我的应用程序中使用facebook登录时,始终返回错误FBErrorCategoryUserCancelled

Question

在我的应用程序中有三种登录方式.其中一个是用facebook登录.但是,当我点击Facebook按钮时,它会询问我访问权限,当点击OK它然后它会重新发出错误FBErrorCategoryUserCancelled.并且这不会发生在每个设备上,它发生在某些设备上.这是我的代码 -

if ([[FBSession activeSession]isOpen]) {
    /*
     * if the current session has no publish permission we need to reauthorize
     */
    if ([[[FBSession activeSession]permissions]indexOfObject:@"publish_actions"] == NSNotFound) {

        [[FBSession activeSession] requestNewPublishPermissions:[NSArray arrayWithObject:@"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends
                                              completionHandler:^(FBSession *session,NSError *error){

                                                  [ProgressHUD dismiss];
                                                  self.view.userInteractionEnabled = YES;

                                              }];

    }else{

        [self fetchUserDetails];
    }

}else{
    /*
     * open a new session with publish permission
     */
    [FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:@"publish_actions"]
                                       defaultAudience:FBSessionDefaultAudienceOnlyMe
                                          allowLoginUI:YES
                                     completionHandler:^(FBSession *session, FBSessionState status, NSError *error) {
                                         if (!error && status == FBSessionStateOpen) {

                                             [self fetchUserDetails];

}

任何帮助将不胜感激.谢谢.

就我而言，这是因为 facebook 应用程序的沙盒模式仍然处于打开状态，因此对于不是该应用程序的管理员/开发人员/测试人员的任何人都会导致 FBErrorCategoryUserCancelled 。

要关闭 Facebook 上的沙盒模式，请转至 https://developers.facebook.com/apps/YOUR_FACEBOOK_APP_ID/review-status/

看看哪里写着“您想让这个应用程序及其所有实时功能向公众开放吗？”，将其设置为“是”。（您可能需要插入联系电子邮件才能访问此选项）。

或者，如果您还不想公开应用程序，请邀请测试人员成为应用程序的管理员/开发人员/测试人员。此人需要先接受您的邀请才能使用它。
