swift - 快速获取数组中的所有联系电话号码

Question

我获取了所有联系人信息，如下所示。目前我刚刚从联系人那里获取了电话号码。 问题是我如何获取字符串数组中联系人的所有电话号码来使用它？

存储数据:

class ContactStruct : NSObject {
        let identifier : String
        let thumbnailImageData : UIImage?
        let givenName : String
        let familyName : String
        let phoneNumbers : String
        let emailAddresses : String

        init(identi:String,img:UIImage?,name:String,family:String,phone:String,email:String) {
            self.identifier = identi
            self.thumbnailImageData = img
            self.givenName = name
            self.familyName = family
            self.phoneNumbers = phone
            self.emailAddresses = email
        }

获取方法:

class func generateModelArray() -> [ContactStruct]{
     let contactStore = CNContactStore()

     var contactsData = [ContactStruct]()

     let key = [CNContactGivenNameKey,CNContactFamilyNameKey,CNContactImageDataKey,CNContactThumbnailImageDataKey,CNContactPhoneNumbersKey,CNContactEmailAddressesKey,CNLabelPhoneNumberMobile] as [CNKeyDescriptor]
     let request = CNContactFetchRequest(keysToFetch: key)
     try? contactStore.enumerateContacts(with: request, usingBlock: { (contact, stoppingPointer) in
         let givenName = contact.givenName
         let familyName = contact.familyName
         let emailAddress = contact.emailAddresses.first?.value ?? ""
         let phoneNumber = contact.phoneNumbers.first?.value.stringValue ?? ""
         let identifier = contact.identifier
        var image : UIImage?
         if contact.thumbnailImageData != nil{
             image = UIImage(data: contact.thumbnailImageData!)!
         }
         contactsData.append(ContactStruct(identi: identifier, img: image, name: givenName, family: familyName, phone: phoneNumber, email: emailAddress as String))
     })
     return contactsData
 }

你可以使用这个

func extractNumber(data: [ContactStruct]) ->[String] 
{
     var arrNumbers = [String]()
     for number in data
          {
              arrNumbers.append(number.phoneNumber)
          }
     return arrNumbers
}

并像这样使用:

let arrayNumbers = extractNumber(data: contactsData)
dump(arrayNumbers) //<- this line prints on console
