ios - facebook-ios-SDK 问题

Question

我刚刚开始使用 facebook-ios-SDK。我正在尝试运行示例应用程序以了解框架的工作原理。我以前从未使用过 FB Graph API，或者确实使用过 FB connect。当应用程序运行时，我可以点击登录按钮，然后 Safari 启动以使用我的帐户授权 FB 应用程序。一旦我授权它，我认为该页面会尝试重定向并切换回示例应用程序但失败了，safari 显示“无法打开页面”。

我哪里错了？

您可能需要设置授权回调。这是来自 SDK 的自述文件:

Bind your application to a URL scheme corresponding to your Facebook application ID. The URL scheme you must bind to is of the format "fb[appId]://", where [appId] is your Facebook application ID. Without this, your application won't be able to handle authorization callbacks. Modify your application's .plist file as follows:

• Under the root key ("Information Property List") add a new row and name the key "URL types".
• Under the "URL types" key that you just added, you should see a key named "Item 0". If not, add a new row with key "Item 0".
• Under the "Item 0" key, add a new row and name the key "URL Schemes".
• Under the "URL Schemes" key that you just added, you should see a key named "Item 0". If not, add a new row with key "Item 0".
• Set the value of "Item 0" to "fb[appId]" where [appId] is your Facebook application ID. Make sure there are no spaces anywhere in this value. For example, if your application's id is 1234, the value should be "fb1234".
