关于 WifiManager.bundle
会产生什么结果
libHandle = dlopen("/System/Library/SystemConfiguration/WiFiManager.bundle/WiFiManager", RTLD_LAZY);
我使用它来获取 ipod os 3.1.2 上的 wifi 信息 ，因为当我 NSLog(@"Result %@",libhandle); 我得到null 答案应该是什么，
谢谢

根据此讨论，执行上述操作将在 iPhone 模拟器上返回 NULL，因为它缺少所需的捆绑包。如果您在设备上仍然遇到此问题，则可能是 Apple 更改了该系统项目的内部文件结构。这就是依赖私有 API 不好的原因之一。
有关 WiFi 监听的更多信息，您可以参考此项目的源代码，因为他们可能已经解决了这些问题。不过，我想再次提醒您，由于私有 API 调用，您将无法向使用此功能的 App Store 提交应用程序。苹果现在正在扫描所有提交的申请以查找这些电话，并立即拒绝它们。
According to this discussion, doing the above will return NULL on the iPhone Simulator, because it lacks the required bundle. If you are still running into issues with this on the device, it might be that Apple has changed the internal file structure for that system item. This is one of the reasons why it is bad to rely in private APIs.
For more on WiFi snooping, you might refer to the source code for this project, because they might have resolved these issues. However, once again I'd like to remind you that you will not be able to submit an application to the App Store that uses this, because of the private API calls. Apple is now scanning all submitted applications for these calls and instantly rejecting them.
