添加的网站未被内容拦截器拦截
Added site is not blocked with content blocker
您好，我正在编写一个简单的内容拦截器应用程序。在这个应用程序中，我想允许用户添加一个他想阻止并阻止它的网站，但由于某些原因，我的内容阻止程序不会阻止新添加的网站。我使用 SFContentBlockerManager.reloadContentBlocker(withIdentifier: blockerIdentifier) 它打印成功但由于某些原因它不起作用。

我 运行 在编写自己的内容拦截器时遇到了类似的问题。当您创建内容拦截器扩展程序时，您还创建了一个 json 文件，该扩展程序从中读取。现在，重要的部分是扩展只从位于扩展包目录中的文件中读取。
据我所知，您正在写入主应用程序包中的 json 文件，然后重新加载内容拦截器。所以内容拦截器只是简单地查看它自己目录中的文件（同样，与主包目录分开）并加载该 json 文件。
要解决此问题，您需要将文件更改实际写入位于扩展包目录中的 json 文件。
这是一个例子：
let groupUrl: NSURL = fileManager.containerURLForSecurityApplicationGroupIdentifier("group.com.mygroup")!
if let path = NSURL(string: "blockerList.json", relativeToURL: groupUrl) {
// write your json data to the path here
SFContentBlockerManager.reloadContentBlockerWithIdentifier("com.my.extension.identifier", completionHandler: nil)
}
另一个需要注意的重要事项是，您必须请求特殊权限才能从扩展包中读取和写入。
