facebook iOS SDK授权，无需重定向到safari [英] facebook iOS SDK authorization without redirect to safari

问题描述

我需要授权在应用程序中访问Facebook，因为我需要将cookies存储在应用程序的后面。所以我希望自动更新发生在网络视图中，而不需要重定向到safari。经过一些研究，我看到了一些这个问题的答案，其中包括更改以下行：

I need to authorize the access to facebook within the app, because I need to store the cookies where they can be used by the app later. So I want that the autorization takes place in a webview without the need for redirecting to safari. After some research I saw some answers for this problem, which consist of changing the following line:

[self authorizeWithFBAppAuth:YES safariAuth:YES];

至

[self authorizeWithFBAppAuth:NO safariAuth:NO];

但是，这对我来说不起作用。它不再重定向到safari了，但也不打开webview。我错过了什么吗？当重定向到Safari后，与Facebook的连接工作正常，所以SDK应该安装得很好。

However, this is not working for me. It does not redirect to safari anymore, but does not open the webview either. Am I missing something? The connection with facebook works fine when redirecting to safari, so the SDK should be well installed.

提前感谢！

编辑

借助FBDialog.m代码中的断点，我可以看到方法 webViewDidFinishLoad：正在被调用，所以我认为它按预期工作。但是，我还将 NSLog（@view％@，self）; 添加到 init的末尾方法在FBDialog.m中，它在控制台中产生文本：

With the help of breakpoints in the FBDialog.m code, I can see that the method webViewDidFinishLoad:is being called, so I assume it is working as expected. However, I also add the line NSLog(@"view %@",self); to the end of the init method in the FBDialog.m, which produces the text in the console:

view< FBLoginDialog：0x4e316f0; frame =（0 0; 0 0）;自动调整= W + H; layer =< CALayer：0x4e321c0>>

正如你可以看到框架的宽度和高度为0，是UIWebView从不出现的原因？
一点帮助将不胜感激。

As you can see the width and height of the frame is 0, 0. Could this be the reason for the UIWebView never show up? A little help would be greatly appreciated.

推荐答案

我发现问题。在窗口的 makeKeyAndVisible 方法之前，我正在调用facebook对象的授权方法。

I found the problem. I was calling the authorize method of the facebook object before the makeKeyAndVisiblemethod of the window.
