Add site with content blocker extension - ios

Question

Hi I am writing a content blocker app.
In this app I want to allow the user add a website that he wants to block.
How can i do that? I used SFContentBlockerManager.reloadContentBlocker(withIdentifier: blockerIdentifier) but it's just activate filter of block list
Thats my protocol on which i write domain(website) how can implement it here to my blocklist in content blocker extension
extension WhiteBlackViewController: AddDomainViewControllerDelegate {
func addDomain(text: String?) {
if listSwitch.isOn {
viewModel.items.append(text ?? "")
viewModel.filtered.append(text ?? "")
tableView.reloadData()
}
}
}
Thats my content blocker:
class ContentBlockerRequestHandler: NSObject, NSExtensionRequestHandling {
func beginRequest(with context: NSExtensionContext) {
let documentFolder = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.cyberGuard")
guard let jsonURL = documentFolder?.appendingPathComponent("whiteList.json") else { return }
let attachment = NSItemProvider(contentsOf: jsonURL)
let item = NSExtensionItem()
item.attachments = [attachment!]
context.completeRequest(returningItems: [item], completionHandler: nil)
}
}

So i already has a solution for this.
You just need create appGroup between your extension and your app
And after that write in another file json and activate it
func activateFilterBlock(fileName: String, website: String, realPath: String) {
viewModel.dictionary.append(["action": ["type": "block"], "trigger": ["url-filter": "\(website)"]])
let jsonData = try! JSONSerialization.data(withJSONObject: viewModel.dictionary, options: .prettyPrinted)
if let json = String(data: jsonData, encoding: String.Encoding.utf8) {
let file = "\(fileName).json"
if let dir = FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.cyberGuard") {
let path = dir.appendingPathComponent(file)
do {
try json.write(to: path, atomically: false, encoding: String.Encoding.utf8)
let id = "\(realPath).json"
SFContentBlockerManager.reloadContentBlocker(withIdentifier: id) {error in
guard error == nil else {
print(error ?? "Error")
return
}
print("Reloaded")
}
} catch {
print(error.localizedDescription)
}
}
}
}
If you want receive this json you just can get it from new created json file
func getJSON(fileName: String, success: #escaping(Success), onError: #escaping(OnError)) {
let groupUrl: URL = FileManager().containerURL(forSecurityApplicationGroupIdentifier: "group.cyberGuard")!
if let path = URL(string: "\(fileName).json", relativeTo: groupUrl) {
do {
let data = try Data(contentsOf: path)
let value = try JSONDecoder().decode(WhiteBlackList.self, from: data)
items = value.map({ $0.trigger.urlFilter })
filtered = value.map({ $0.trigger.urlFilter })
if let json = try? JSONSerialization.jsonObject(with: data, options: .allowFragments) as? [[String: [String: Any]]] {
dictionary = json
}
success()
} catch {
onError(error.localizedDescription)
}
}
}
If it helps, let me know :)
