以编程方式删除自定义电话标签 [英] Programmatically delete custom phone labels

问题描述

在iOS中，可以为电话号码和电子邮件地址创建自定义标签.有没有办法以编程方式(使用CNContacts或ABAddressBook)删除那些创建的标签?换句话说:我不想从联系人中删除自定义标签，而是要从系统中删除自定义标签"，因此当有人显示可用列表时，它根本不会显示.

附加的iOS 9源代码，可在电话簿中创建联系人，并在电子邮件字段上使用自定义标签.

  func createContact(){让contactStore = CNContactStore()让newContact = CNMutableContact()newContact.givenName =克里斯"newContact.familyName =最后一个"let homeEmail = CNLabeledValue(标签:"RandomLabel"，值:"[e-mail]")newContact.emailAddresses = [homeEmail]做 {让saveRequest = CNSaveRequest()saveRequest.addContact(newContact，toContainerWithIdentifier:nil)尝试contactStore.executeSaveRequest(saveRequest)}抓住 {NSLog(保存失败")}} 

解决方案

Contact Framework + deleteContact

这可能会对您有所帮助.

使用此功能

我今天过得很好:

  NSOperationQueue().addOperationWithBlock {[unown store] in让谓词= CNContact.predicateForContactsMatchingName("john")让toFetch = [CNContactEmailAddressesKey]做{让通讯录=尝试store.unifiedContactsMatchingPredicate(predicate，keysToFetch:toFetch)守卫contacts.count>其他0个{打印(未找到联系人")返回}//仅对符合我们条件的第一个联系人执行此操作警卫让contact = contacts.first else {返回}让req = CNSaveRequest()让mutableContact = contact.mutableCopy()为！CNMutableContactreq.deleteContact(mutableContact)做{尝试store.executeSaveRequest(req)打印(成功删除用户")}赶快让e {print(错误= \(e)")}}抓住让犯错{打印(错误)}} 

似乎可以，但是您需要执行以下批处理功能:

• 使用AddressBook/ABAddressBookCopyArrayOfAllPeople获取联系人
• 用于...进入联系人
• 获取ABRecordCopyValue以获取所需的ABMultiValueRef
  • kABPersonEmailProperty
  • kABPersonAddressProperty
  • kABPersonPhoneProperty
• 为了...融入其中
• 通过ABMultiValueCopyLabelAtIndex获取当前数据
• 将其与默认标签进行比较(请注意

  Attached iOS 9 source code that creates a contact in the phone book with custom labels on the email field.

  func createContact() {
  
      let contactStore = CNContactStore()
      let newContact = CNMutableContact()
  
      newContact.givenName = "Chris"
      newContact.familyName = "Last"
  
      let homeEmail = CNLabeledValue(label: "RandomLabel", value: "[e-mail]")
      newContact.emailAddresses = [homeEmail]
  
      do {
          let saveRequest = CNSaveRequest()
          saveRequest.addContact(newContact, toContainerWithIdentifier: nil)
          try contactStore.executeSaveRequest(saveRequest)
      }
      catch {
          NSLog("Save failed")
      }
  }
  

  解决方案

  Contact Framework + deleteContact

  This might help you.

  Using this function

  EDIT: I'm in a good day:

  NSOperationQueue().addOperationWithBlock{[unowned store] in
    let predicate = CNContact.predicateForContactsMatchingName("john")
    let toFetch = [CNContactEmailAddressesKey]
  
    do{
  
      let contacts = try store.unifiedContactsMatchingPredicate(predicate,
        keysToFetch: toFetch)
  
      guard contacts.count > 0 else{
        print("No contacts found")
        return
      }
  
      //only do this to the first contact matching our criteria
      guard let contact = contacts.first else{
        return
      }
  
      let req = CNSaveRequest()
      let mutableContact = contact.mutableCopy() as! CNMutableContact
      req.deleteContact(mutableContact)
  
      do{
        try store.executeSaveRequest(req)
        print("Successfully deleted the user")
  
      } catch let e{
        print("Error = \(e)")
      }
  
    } catch let err{
      print(err)
    }
  }
  

  EDIT: It seems you can but you need to do batch function like this:

  • fetch contacts using AddressBook/ABAddressBookCopyArrayOfAllPeople
  • For...in into contacts
  • get the ABRecordCopyValue to get the ABMultiValueRef you want
    • kABPersonEmailProperty
    • kABPersonAddressProperty
    • kABPersonPhoneProperty
  • For...in into them
  • Get the current with ABMultiValueCopyLabelAtIndex
  • Compare it to the default labels (note here to get the default one)
  • if no match, delete it

  Hope it helps you

  EDIT 2: Meh, ABAddressBook is deprecated, you need to do the same with New contact framework ... Have fun !!
