如何使用CNContacts在swift中仅获取手机号码？ [英] How to fetch only mobile numbers in swift using CNContacts?

问题描述

我有一些代码可以检索用户联系人中的所有电话号码，但我们只想过滤掉手机号码。目前，我只是将数字的第一个数字+或第二个数字7添加到数组中，如下所示：

I have some code to retrieve all the phone numbers in the users contacts, but would like to filter out only mobile numbers. Currently, I am just doing this by only adding numbers with a first digit of "+" or second digit of "7" to an array, as shown below:

    func findContacts () -> [CNContact]{
    let keysToFetch = [CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName),CNContactPhoneNumbersKey]
    let fetchRequest: CNContactFetchRequest = CNContactFetchRequest(keysToFetch: keysToFetch)
    var contacts = [CNContact]()
    CNContact.localizedStringForKey(CNLabelPhoneNumberiPhone)
    fetchRequest.mutableObjects = false
    fetchRequest.unifyResults = true
    fetchRequest.sortOrder = .UserDefault

    let contactStoreID = CNContactStore().defaultContainerIdentifier()

    do {

        try CNContactStore( ).enumerateContactsWithFetchRequest(fetchRequest) { (let contact, let stop) -> Void in
            if contact.phoneNumbers.count > 0 {
                contacts.append(contact)
            }
            if (contact.isKeyAvailable(CNContactPhoneNumbersKey)) {
                for phoneNumber:CNLabeledValue in contact.phoneNumbers {
                    let number = phoneNumber.value as! CNPhoneNumber
                    print(number.stringValue)
                    let index = number.stringValue.startIndex.advancedBy(1)
                    let indexPlus = number.stringValue.startIndex.advancedBy(0)
                    if number.stringValue[index] == Character(String(7)) || number.stringValue[indexPlus] == Character("+"){
                        self.allNumbers.append("\(number.stringValue)")
                    }
                }
            }
        }

由于联系人存储在带有移动标签的iPhone上，我是想知道是否只能将这些数字添加到数组中。谢谢：）

Since contacts are stored on an iPhone with a "mobile" label, I was wondering if only these numbers could be added to the array. Thanks :)

推荐答案

检查号码的标签是否像这样移动：

Check if the number's label is mobile like this:

var mobiles = [CNPhoneNumber]()

for num in contact.phoneNumbers {
    let numVal = num.value as! CNPhoneNumber
    if num.label == CNLabelPhoneNumberMobile {
        mobiles.append(numVal)
    }
}

然后你有一系列的手机号码。

Then you have an array of mobile phone numbers for that person.
