swift – 在附加电话号码时联系框架崩溃应用程序

在尝试更新现有联系人时,我收到sigabrt错误“提取联系人时未请求属性”.

var cntct= existingContact.mutableCopy() as! CNMutableContact

let phone= CNLabledValue(label:CNLabelPhoneNumberMain, value:"786967655566") 

cntct.phoneNumbers.append(phone)

我一直在与自己的相关问题苦苦挣扎几个小时：我需要为swift的联系人添加生日.通过一些研究,试验和错误以及故障排除,以下是我提出的建议：

var contactStore = CNContactStore()
    var contactx:CNMutableContact = CNMutableContact()

    let predicate = CNContact.predicateForContactsMatchingName("\(firstnamefield.text!) \(lastnamefield.text!) \(suffixfield.text!)") // searches for contacts matching the inserted name (inputted by the user as first name, then last name, then any suffixes).

    let toFetch = [CNContactBirthdayKey]
    do{
        var contacts = try contactStore.unifiedContactsMatchingPredicate(
            predicate, keysToFetch: toFetch)

        print(contacts)

        for contact in contacts {

            let birthday = NSDateComponents()
            birthday.year = Int(yearfield.text!)! // sets the birthday year
            birthday.month = Int(monthfield.text!)! // sets the birthday month
            birthday.day = Int(dayfield.text!)! // sets the birthday day

            let mutableContact = contact.mutableCopy() as! CNMutableContact
            mutableContact.birthday = birthday // sets the contacts found with predicate search to having the birthday set above.

            let saveRequest = CNSaveRequest()
            saveRequest.updateContact(mutableContact)
            try contactStore.executeSaveRequest(saveRequest)

显然,这会增加生日而不是电话号码,但您可以使用完全相同的原则(谓词搜索,联系人中的联系人)来添加电话号码;只是改变联系人循环中联系人内部发生的事情！我希望这会对你有所帮助,抱歉你没有早点得到答复.

基本上,您可以更改联系循环内部的内容

let phone= CNLabledValue(label:CNLabelPhoneNumberMain, value:"786967655566") 

cntct.phoneNumbers.append(phone)

你应该有一个电话号码添加过程.
