如何让 CoreSpotlight 预测谁在打电话

Question

我希望我的设备能够根据聚光灯人物指数预测谁在给我打电话。我已将人员信息上传到聚光灯索引，系统会在我搜索时提供信息，但在有人打电话时不会。下面的代码做了所有这些事情，我不明白出了什么问题

if people.count > 0 {
    var peopleArray = [CSSearchableItem]()
    var peopleGUIDs = [String]()
    for person in people {
        let attributeSet = CSSearchableItemAttributeSet(itemContentType: kUTTypeText as String)

        // Basic AttributeSet setup
        attributeSet.title = person.nameForList
        attributeSet.contentDescription = person.division?.title

        // Add first phone number to AttributeSet
        var phoneNumber: NSString?
        let contacts = Array(person.contacts)
        for contact in contacts {
            if contact.type == "phone" {
                phoneNumber = contact.value as NSString
                break
            }
        }
        if phoneNumber != nil {
            if let preparedNumber = phoneNumber!.removingPercentEncoding {
                attributeSet.phoneNumbers = [preparedNumber]
                attributeSet.supportsPhoneCall = true
            }
        }

        attributeSet.displayName = person.name

        // Add photo number to AttributeSet
        if let photoPath = person.photo {
            let key = SDWebImageManager.shared().cacheKey(for: NSURL(string: photoPath) as URL!)
            let image = SDImageCache.shared().imageFromDiskCache(forKey: key)
            var data = Data()
            if let image = image {
                if let dataFromImage = UIImagePNGRepresentation(image) {
                    data = dataFromImage
                }
            } else {
                data = dataFromImage
            }
            attributeSet.thumbnailData = data
        }

        peoplesGUIDs.append(person.id)

        let item = CSSearchableItem(uniqueIdentifier: person.id, domainIdentifier: "com.it.companySpotlight", attributeSet: attributeSet)
        peopleArray.append(item)
    }

    CSSearchableIndex.default().indexSearchableItems(peopleArray) {  (error) in
        DispatchQueue.main.async(execute: {
            if let error =  error {
                print("Indexing error: \(error.localizedDescription)")
            } else {
                print("Search for people successfully indexed")
            }
        })
    }

}

有人知道如何解决这个问题吗？

Answer 1

过了一会儿，Paulw11说我需要用户CallKit扩展，所以有解决办法：

1. 将新目标添加到您的项目“CallKIt 扩展”
2. 创建应用组以向您的扩展程序提供带有电话号码的文本文件，因为无法使用那里的数据库
3. 请确保您的联系人按数字升序排列以获得更好的性能

4. 将联系人写入文件

   if #available(iOS 10.0, *) {
       let numbers = ["79175870629"]
   
       let labels = ["Stranger name"]
   
       // Replace it with your id
       let groupId = "group.YOUR.ID"
       let container = FileManager.default
           .containerURL(forSecurityApplicationGroupIdentifier: groupId)
       guard let fileUrl = FileManager.default
           .containerURL(forSecurityApplicationGroupIdentifier: groupId)?
           .appendingPathComponent("contacts") else { return }
   
       var string = ""
       for (number, label) in zip(numbers, labels) {
           string += "\(number),\(label)\n"
       }
   
       try? string.write(to: fileUrl, atomically: true, encoding: .utf8)
   
       CXCallDirectoryManager.sharedInstance.reloadExtension(
           withIdentifier: groupId)
   } else {
       // Fallback on earlier versions
   }
   

5. 然后将类 LineReader 添加到您的扩展 from this post

6. 调用reloadExtension时会调用该方法

   override func beginRequest(with context: CXCallDirectoryExtensionContext) {
   context.delegate = self
   if #available(iOSApplicationExtension 11.0, *) {
       if context.isIncremental {
           addOrRemoveIncrementalBlockingPhoneNumbers(to: context)
           addOrRemoveIncrementalIdentificationPhoneNumbers(to: context)
       } else {
           addAllBlockingPhoneNumbers(to: context)
           addAllIdentificationPhoneNumbers(to: context)
       }
   } else {
       addAllBlockingPhoneNumbers(to: context)
       addAllIdentificationPhoneNumbers(to: context)
   }
   
   
   context.completeRequest()
   

   }

7. 就我而言，我只实现了 addAllIdentificationPhoneNumbers 并从文件中读取联系人。您需要为默认生成的所有其他方法添加逻辑

   guard let fileUrl = FileManager.default
               .containerURL(forSecurityApplicationGroupIdentifier: "group.YOUR.ID")?
               .appendingPathComponent("contacts") else { return }
   
           guard let reader = CBLineReader(path: fileUrl.path) else { return }
           print("\(#function) \(fileUrl)")
           for line in reader {
               autoreleasepool {
                   let line = line.trimmingCharacters(in: .whitespacesAndNewlines)
   
                   var components = line.components(separatedBy: ",")
   
                   guard let phone = Int64(components[0]) else { return }
                   let name = components[1]
   
                   context.addIdentificationEntry(withNextSequentialPhoneNumber: phone, label: name)
                   print(#function + name)
               }
           }
   

8. 转到设置 -> 电话 -> 呼叫阻止和识别 -> 在您的应用程序对面打开 swift

9. 测试您的应用 :-) 希望它对某人有所帮助
