iOS Facebook SDK 在 iOS 4.1 和 4.2 中崩溃

【中文标题】iOS Facebook SDK 在 iOS 4.1 和 4.2 中崩溃

【英文标题】：iOS Facebook SDK crashing in iOS 4.1 & 4.2

【发布时间】：2011-12-09 19:05:02

【问题描述】：

是我还是其他人在使用 Facebook SDK 的那些 ios 版本上崩溃了。它发生在你要分享时，然后它给你一个错误的访问权限，调试器说“decodeGIFFrame”......经过一番研究我注意到 Facebook html 正在返回一个带有空引用的图像 "img src="/images/icons/default_app_icon.gif" />" 但我不认为图像的 "null" 引用会导致崩溃，而是渲染gif的...如何修复？

它发生在 Facebook webView 委托响应“webViewDidFinishLoad:”之后

【问题讨论】：

您可能需要显示一些代码（靠近并包括崩溃发生的位置），以及回溯。

编辑了我的帖子，希望对您有所帮助

我在 ios4 上遇到了完全相同的问题 :(

问题确实是GIF图片，看这个问题：***.com/questions/8411307/…

我会尝试他们的解决方案，看看它是否有效，谢谢您的建议

【参考方案1】：

需要在 Facebook.m 中替换文本：

static NSString* kDialogBaseURL = @"https://m.facebook.com/dialog/";

与

static NSString* kDialogBaseURL = @"https://www.facebook.com/dialog/";

【讨论】：

哇，它确实有效，哈哈，但我想知道它为什么有效：P 感谢您的建议

我在关闭对话框时遇到了 EXC_BAD_ACCESS 崩溃。将 kDialogBaseURL 值更改为上面列出的值可以修复它。很奇怪，但我只是想分享一下我的经验，以防其他人遇到。
