访问通讯录时出现重复

Question

由于某些原因，我不断地在我的代码能够访问的许多联系人上得到重复的内容。有什么原因吗？

var error: Unmanaged<CFError>?
addressBook = ABAddressBookCreateWithOptions(nil, &error).takeRetainedValue()


   if let people = ABAddressBookCopyArrayOfAllPeopleInSourceWithSortOrdering(self.addressBook, nil, ABPersonSortOrdering(kABPersonSortByFirstName)).takeRetainedValue() as? NSArray {
        for record in people {
            //var contactPerson: ABRecordRef = record
            var contactName: String = ABRecordCopyCompositeName(record).takeRetainedValue() as String


            var number = ""

            var phones: ABMultiValueRef = ABRecordCopyValue(record, kABPersonPhoneProperty).takeRetainedValue()

            for j in 0..<ABMultiValueGetCount(phones) {
                number = ABMultiValueCopyValueAtIndex(phones, j).takeRetainedValue() as! String
                break
            }

            if (number != "") {
                var newPerson = personInfo(name: contactName, number: number)
                allContacts.append(newPerson)
            }


           self.tableView.reloadData()
        }
    }

James Richards请使用联系人框架，而不是使用通讯录。

首先，您应该通过构建阶段->将二进制文件与库链接->添加(单击+)->choose联系人框架来添加联系人框架

import Contacts 

然后

let status = CNContactStore.authorizationStatusForEntityType(.Contacts)
if status == .Denied || status == .Restricted {
        // user previously denied, so tell them to fix that in settings
        return
}

// open it

let store = CNContactStore()
store.requestAccessForEntityType(.Contacts) { granted, error in
        guard granted else {
            dispatch_async(dispatch_get_main_queue()) {
                // user didn't grant authorization, so tell them to fix that in settings
                print(error)
            }
            return
}

// get the contacts

var contacts = [CNContact]()
let request = CNContactFetchRequest(keysToFetch:[CNContactIdentifierKey, CNContactFormatter.descriptorForRequiredKeysForStyle(.FullName)])
   do {
      try store.enumerateContactsWithFetchRequest(request) { contact, stop in
                contacts.append(contact)
         }
   } 
   catch {
            print(error)
         }

        // do something with the contacts array (e.g. print the names)

        let formatter = CNContactFormatter()
        formatter.style = .FullName
        for contact in contacts {
            print(formatter.stringFromContact(contact))
        }
 }

输出结果

Optional("John Appleseed")
Optional("Kate Bell")
Optional("Anna Haro")
Optional("Daniel Higgins Jr.")
Optional("David Taylor")
Optional("Hank M. Zakroff")
