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.
