如何使用CNContacts在swift中仅获取手机号码？

Question

我有一些代码可以检索用户联系人中的所有电话号码,但只想过滤掉手机号码.目前,我只是通过向数组中添加第一个数字"+"或第二个数字"7"的数字来实现此目的,如下所示:

    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,我想知道是否只能将这些数字添加到阵列中.谢谢 :)

Answer 1

检查号码的标签是否像这样移动:

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给那个人.
