Facebook SDK登录对话框出现两次 [英] Facebook SDK Login dialog appears twice

问题描述

在我的项目是下面的代码，它发送一些消息到用户feed：

In my project is the next code which sends some message to user feed:

[facebook authorize:permissions delegate:self];
[facebook dialog:@"feed" andParams:params andDelegate:self];

但是当我用这个代码调用函数时，登录对话框出现两次。我如何解决这个问题？感谢

But when I call function with this code, login dialog appears twice. How can I solve this problem? Thanks

推荐答案

登录对话框不会出现两次。两个登录对话框同时显示。上述两行都将打开一个对话框。所以如果你把这些行一起，两个对话框将一起打开。如果你还没有登录到 Facebook ，显然这两个对话框都会打开登录页面。

Login dialog is not appearing twice. Two Login dialogs are appearing at the same time. Both the above lines will open a dialog. So if you call those lines together, two dialogs will be opened together. If you are not already logged in to Facebook, obviously both the dialogs will open the Login page.

[facebook authorize:permissions delegate:self];

登录后授权结束，请致电

Once you logged in and the authorization is over, call

[facebook dialog:@"feed" andParams:params andDelegate:self];
