摘要
尝试编写 a 代码,INSendPaymentIntent但在区分具有相似名字的联系人时遇到了问题。Siri似乎在之后就进入了循环INPersonResolutionResult.disambiguation(with: matchedContacts)

代码背后的想法
我最初选择使用联系人的名字来搜索联系人,因为INPerson如果用户只指定名字,则使用显示名称会返回与查询匹配的第一个联系人。(即“支付凯文 50 美元”将自动选择凯文培根而不是凯文史派西)

不幸的是,使用给定的名字会使 Siri 进入一个循环,要求用户一遍又一遍地指定联系人......

问题
是否有任何方法可以使用联系人的名字搜索联系人而不将 Siri 发送到循环中?

代码

func resolvePayee(forSendPayment intent: INSendPaymentIntent, with completion: (INPersonResolutionResult) -> Void) {
    if let payee = intent.payee {
        var resolutionResult: INPersonResolutionResult?
        var matchedContacts: [INPerson] = []
        let predicate = CNContact.predicateForContacts(matchingName: (payee.nameComponents?.givenName)!)

        do {
            let searchContactsResult = try CNContactStore().unifiedContacts(matching: predicate, keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey, CNContactIdentifierKey])
            for contact in searchContactsResult {
                matchedContacts.append(createContact((contact.phoneNumbers.first?.value.stringValue)!, contact: contact))
            }
        } catch {
            completion(INPersonResolutionResult.unsupported())
        }

        switch matchedContacts.count {
            case 2 ... Int.max:
                resolutionResult = INPersonResolutionResult.disambiguation(with: matchedContacts)
            case 1:
                let recipientMatched = matchedContacts[0]
                print("Matched a recipient: \(recipientMatched.displayName)")
                resolutionResult = INPersonResolutionResult.success(with: recipientMatched)
            case 0:
                print("This is unsupported")
                resolutionResult = INPersonResolutionResult.unsupported()
            default:
                break
        }

        completion(resolutionResult!)
    } else {
        completion(INPersonResolutionResult.needsValue())
    }
}

每当您返回此信息时,Siri 都会要求确认此人的姓名:

completion(INPersonResolutionResult.needsValue())

或这个:

completion(INPersonResolutionResult.disambiguation(with: matchedContacts))

在这种情况下,我认为它更有可能进入循环,因为您一直返回第二个结果 ( INPersonResolutionResult.disambiguation)。这意味着您在此行中的查询不断返回 2 人或更多人:

let searchContactsResult = try CNContactStore().unifiedContacts(matching: predicate, keysToFetch:[CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactPhoneNumbersKey, CNContactImageDataKey, CNContactIdentifierKey])

我建议您调试该行,看看您是否曾经将这个值返回给 Siri:

INPersonResolutionResult.success
