如何检测是否有任何外部库正在调用[UIDevice currentDevice] uniqueIdentifier]？

Question

因此,由于Apple现在拒绝访问UDID的应用程序,在我们公司的当前项目中,我们需要删除所有调用此属性的API:

[[UIDevice currentDevice] uniqueIdentifier]

我们已经消除了我们自己的代码中的所有调用,但需要确保我们使用的许多外部库不会调用此属性.

确定库是否正在调用此属性的最可靠方法是什么？

先感谢您!

除了使用otx(似乎已经变得片状)之外,一个选项是在该方法上设置符号断点,然后运行应用程序一段时间,看看你是否点击它.

为该方法配置符号断点将如下所示:

如果你遇到了那个断点,你可以通过打开调试器控制台并输入来找出谁调用它bt.在这种情况下,呼叫来自我,application:didFinishLaunchingWithOptions:但无论是谁调用它都有效:
