推荐答案

假设您正在编写要在应用商店中发布的应用，则不能-UIWebView的结构对您来说是不透明的，并且可以' t深入了解其组成部分.尽管我怀疑是否有可能深入了解其结构，并弄清楚何时触发了什么，但您冒着很大的风险，苹果将在随后的OS更新中更改UIWebView的结构并破坏您的应用程序.

Assuming you're writing an app to release on the app store, you can't - the structure of a UIWebView is opaque to you, and you can't drill down into its component parts. Whilst I suspect it would be possible to descend into its structure and figure out exactly what was getting triggered when, you run a very large risk that Apple will change UIWebView's structure in a subsequent OS update and break your app.

因此，除非您不使用公共API(因此可以通过应用商店以外的渠道使用)，否则恐怕您可能不走运.

So unless you're going outside of the public API (and thus making available through channels other than the app store) I'm afraid you may be out of luck.
