Question

我是Swift的新手。从iPhone导出联系人并将其转换为.Vcf文件以便将文件上传到Web服务器时遇到问题。此外，我想从Web服务器导入.Vcf文件并将其转换为iPhone联系人的模式。谁能帮我达到预期的效果吗？。

请尝试以下代码段。

public func processContacts() throws {

        let contactStore = CNContactStore()
        let status = CNContactStore.authorizationStatus(for: .contacts)


        switch status {
        case .denied:
            throw ContactAccessError(description: "Access Denied")
        case .notDetermined:
            // In case of not determined request for access
            // If allowed it will return success otherwise return error
            contactStore.requestAccess(for: .contacts, completionHandler:{ success, error in
                if success {

                    print("Access Allowed")
                    var contacts = [CNContact]()
                    let request = CNContactFetchRequest(keysToFetch: [CNContactIdentifierKey as NSString, CNContactFormatter.descriptorForRequiredKeys(for: .fullName)])
                    do {
                        try contactStore.enumerateContacts(with: request) { contact, stop in
                            contacts.append(contact)
                        }
                    } catch {
                        print(error)
                    }
                    for contact in contacts{
                        do{
                            var data = Data()
                            try data = CNContactVCardSerialization.data(with: [contact])
                            let fileManager = FileManager.default
                            do {
                                let documentDirectory = try fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor:nil, create:false)
                                let fileURL = documentDirectory.appendingPathComponent("someName").appendingPathExtension("vcf")
                                try data.write(to: fileURL)
                            } catch {
                                print(error)
                            }
                        }catch{
                            print("Some Error")
                        }
                    }
                }
            })
        default:
            break
        }
    }

    class ContactAccessError: LocalizedError {

        private var desc = ""

        init(description: String) {
            desc = description
        }

        var errorDescription: String? {
            get {
                return self.desc
            }
        }
    }
