以编程方式删除自定义电话标签

本文介绍了以编程方式删除自定义电话标签的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 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:"IGotAnEmail@Address")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(请注意此处获取默认值)
• 如果没有匹配项，请将其删除

希望对您有帮助

不建议使用ABAddressBook，您需要对新的联系人框架 ...玩得开心！

In iOS it is possible to create custom labels for phone numbers and email addresses. Is there a way to remove those created labels programatically (either with CNContacts or ABAddressBook)? In other words: I don't want to delete the custom label from a contact, I want to delete the "custom label" from the system so it doesn't show up at all when someone brings up the available available list.

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: "IGotAnEmail@Address") 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 !!
