ios - 如何将联系人保存到 iOS 中的联系人应用程序中 - Swift

Question

我试图在不请求任何许可的情况下直接使用此代码将联系人保存到联系人应用程序:

import Foundation
import UIKit
import Contacts

@available(iOS 9.0, *)
class OnCallEmpContact: UITableViewController {

    var store: CNContactStore!

    @IBOutlet weak var nameLabel: UILabel!

    @IBOutlet weak var phoneLabel: UILabel!

    @IBOutlet weak var emailLabel: UILabel!

    @IBOutlet weak var workPhoneLabel: UILabel!



    var emp = employee()
    var rank = ""

    override func viewDidLoad() {
        super.viewDidLoad()
        self.nameLabel.text=self.emp.getFistName()+" "+emp.getLastName()
        self.phoneLabel.text="0"+self.emp.getMobile()
        self.emailLabel.text=self.emp.getEmail()
        self.workPhoneLabel.text=self.emp.getPhone()

        store = CNContactStore()
        checkContactsAccess()


    }

    private func checkContactsAccess() {
        switch CNContactStore.authorizationStatusForEntityType(.Contacts) {
            // Update our UI if the user has granted access to their Contacts
        case .Authorized:
            self.accessGrantedForContacts()

            // Prompt the user for access to Contacts if there is no definitive answer
        case .NotDetermined :
            self.requestContactsAccess()

            // Display a message if the user has denied or restricted access to Contacts
        case .Denied,
        .Restricted:
            let alert = UIAlertController(title: "Privacy Warning!",
                message: "Permission was not granted for Contacts.",
                preferredStyle: .Alert)
            alert.addAction(UIAlertAction(title: "OK", style: .Default, handler: nil))
            self.presentViewController(alert, animated: true, completion: nil)
        }
    }

    private func requestContactsAccess() {

        store.requestAccessForEntityType(.Contacts) {granted, error in
            if granted {
                dispatch_async(dispatch_get_main_queue()) {
                    self.accessGrantedForContacts()
                    return
                }
            }
        }
    }

    // This method is called when the user has granted access to their address book data.
    private func accessGrantedForContacts() {
        //Update UI for grated state.
        //...
    }


    override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String? {
        if section == 0{
        if rank == "0"{
        return "Primary Employee"
        }
        else if rank == "1"{
        return "Backup Employee"
        }
        }
        return""
    }

    override  func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {

        tableView.deselectRowAtIndexPath(indexPath, animated: true) // to stop highliting the selected cell

        if indexPath.section==1 && indexPath.row==0{
                self.saveContact()
        }


    }



    func saveContact(){
        do{
            let contact = CNMutableContact()
        contact.givenName = self.emp.getFistName()
        contact.familyName = self.emp.getLastName()
        contact.phoneNumbers = [CNLabeledValue(
            label:CNLabelPhoneNumberiPhone,
            value:CNPhoneNumber(stringValue:emp.getMobile())),
                  CNLabeledValue(
                label:CNLabelPhoneNumberiPhone,
                value:CNPhoneNumber(stringValue:emp.getPhone()))]

        let workEmail = CNLabeledValue(label:CNLabelWork, value:emp.getEmail())
        contact.emailAddresses = [workEmail]


        let saveRequest = CNSaveRequest()
        saveRequest.addContact(contact, toContainerWithIdentifier:nil)
        try store.executeSaveRequest(saveRequest)
            print("saved")

        }

        catch{
            print("error")
        }
    }



}

我在方法 saveContact 的最后一行 try store.executeSaveRequest(saveRequest) 出现错误

错误:

fatal error: 'try!' expression unexpectedly raised an error: Error Domain=CNErrorDomain Code=100 "Access Denied" UserInfo={NSLocalizedDescription=Access Denied, NSLocalizedFailureReason=This application has not been granted permission to access Contacts.

我在 apple 网站上找到了上面的代码，但我也在中间的隐私部分标出了这个:

Any call to CNContactStore will block the application while the user is being asked to grant or deny access

但是没有任何内容要求访问联系人应用程序。我应该编写更多代码来执行此操作吗？怎么样？

错了!使用 do-catch 语句就可以了。

do {
  try store.executeSaveRequest(saveRequest)
} catch {}

希望对您有所帮助。
