CNContact를 UserDefaults에 저장합니다.

Question

CNContact 세부 정보를 내 UserDefaults에 저장하려고했지만 실패합니다. 다른 방법으로 저장할 수 있습니까 CNContact?

struct User { 
    var firstName: String = "" 
    var lastName: String = "" 
    var email: String = "" 
    var phoneNumber: String = "" 
    var company: String = "" 
    var assistantContact: CNContact? 

    init(firstName: String, lastName: String, email: String, phoneNumber: String, company: String, assistantContact: CNContact? = nil) { 
     self.firstName = firstName 
     self.lastName = lastName 
     self.email = email 
     self.phoneNumber = phoneNumber 
     self.company = company 
     self.assistantContact = assistantContact 
    } 

    func encode() -> Dictionary<String, AnyObject> { 

     var dictionary : Dictionary = Dictionary<String, AnyObject>() 
     dictionary["firstName"] = firstName as AnyObject? 
     dictionary["lastName"] = lastName as AnyObject? 
     dictionary["email"] = email as AnyObject? 
     dictionary["phoneNumber"] = phoneNumber as AnyObject? 
     dictionary["company"] = company as AnyObject? 
     dictionary["assistantContact"] = assistantContact as AnyObject? 
     return dictionary 

    } 

    init(dictionary: Dictionary<String, AnyObject>) { 
     if let firstName = dictionary["firstName"] as? String { 
      self.firstName = firstName 
     } 
     if let lastName = dictionary["lastName"] as? String { 
      self.lastName = lastName 
     } 
     if let email = dictionary["email"] as? String { 
      self.email = email 
     } 
     if let phoneNumber = dictionary["phoneNumber"] as? String { 
      self.phoneNumber = phoneNumber 
     } 
     if let company = dictionary["company"] as? String { 
      self.company = company 
     } 
     if let assistantContact = dictionary["assistantContact"] as? CNContact { 
      self.assistantContact = assistantContact 
     } 
    } 

} 

Answer 1

첫 번째 인코딩 연락처 배열을 사용 중입니다.

let encodedData: Data = NSKeyedArchiver.archivedData(withRootObject: contactsArray) 

이제 UserDefaults에 encodedData를 저장하십시오. * UserDefaults 클래스는 일반적인 유형 등을 액세스하기위한 편리한 방법을 제공합니다

디코드 연락처 배열

는

if let contacts: [CNContact] = decodedData as? [CNContact] { 
      //Decoded Contacts Array 
}
