用
self.context = [self.webView valueForKeyPath:@"documentView.webView.mainFrame.javaScriptContext"];
取得 JSContext 的方法会不会审核被拒？
查了下拒不拒都有例子。。不敢用了都

不会，从 iOS8.2 开始允许使用 JavascriptCore 来动态执行代码。

@lynulzy 因为 documentView.webView.mainFrame.javaScriptContext 不在官方文档里

@xi_lin 准确说是从 iOS7 开始公开了 JSC 的接口，发布 iOS8.2 的时候修改了开发者协议，内容如下
> 3.3.2 An Application may not download or install executable code. Interpreted code may only be used in an Application if all scripts, code and interpreters are packaged in the Application and not downloaded. The only exception to the foregoing is scripts and code downloaded and run by Apple's built-in WebKit framework, provided that such scripts and code do not change the primary purpose of the Application by providing features or functionality that are inconsistent with the intended and advertised purpose of the Application as submitted to the App Store. 实际上就意味着允许开发者直接使用 JavascriptCore 接口来进行一些更加``奇妙``的操作 |

xi_lin OP @lynulzy 主要是想简化 js -> native 这一步，有了 JSContext 就可以直接 JSExport 直接调用方法了

xi_lin OP @siroccoicode 原来如此，谢谢！
