如何取消Facebook登录? [英] How to cancel facebook login?

问题描述

我刚刚在我的移动游戏应用程序中添加了 facebook 功能，并根据教程

I have just added a facebook feature to my mobile game-app and implemented SSO (Single Sign-On) according to the tutorial https://developers.facebook.com/docs/mobile/ios/build/.

如果用户尚未安装facebook的应用程序，则SSO将启动显示facebook登录页面的safari.但是，某些用户可能不喜欢继续(他们甚至可能没有Facebook帐户).

If the user has not installed facebook's app, SSO launches safari which displays the facebook login page. However, some users may not like to proceed (they may not even have a facebook account).

我可以以某种方式配置SSO，以使用户无需登录Facebook即可回滚并返回游戏吗?

Can I somehow configure SSO to make it possible for the user to roll back and return to the game without logging in to facebook?

推荐答案

替代方法:您可以在 Facebook.m 中将authorize方法更改为具有inAuthApp标志:

An alternative: You could change the authorize method in Facebook.m to have an inAuthApp flag:

  - (void)authorize:(NSArray *)permissions usingInAppAuth: (BOOL) inAppAuth {
      self.permissions = permissions;
      [self authorizeWithFBAppAuth: (inAppAuth) ? NO : YES safariAuth: (inAppAuth) ? NO : YES];
  }

此代码:

[facebook authorize:permissions usingInAppAuth:YES];

强制身份验证过程在UIWebView中运行，并且用户可以在不离开应用程序的情况下取消该过程.

forces the authentication process to work inside a UIWebView and there the user could cancel the process without leaving the app.
