如何使用Swift联系人对联系人进行排序 [英] How to sort contacts using Contacts with Swift

问题描述

我已经阅读了有关排序联系人的官方苹果文档，但我不确定如何实现它。
所以，这里是获取请求：

 让fetchRequest = CNContactFetchRequest（keysToFetch：keysToFetch）
  

和我的首选排序顺序：

  let sortOrder = CNContactSortOrder.UserDefault 
  

这就是我通常获取联系人的方式：

  do {
 try store.enumerateContactsWithFetchRequest（fetchRequest，usingBlock：{（let contact，let stop） - > Void in 
 self.contacts.append（contact）
}）
} 
 catch错误为NSError {
 print（error.localizedDescription）
} 
  

现在我该如何处理 sortOrder ？我应该在整个提取过程中包括哪些内容？

解决方案

更新为Swift 4.0

 让fetchRequest = CNContactFetchRequest（keysToFetch：[CNContactGivenNameKey as CNKeyDescriptor，CNContactFamilyNameKey as CNKeyDescriptor，CNContactMiddleNameKey as CNKeyDescriptor，CNContactEmailAddressesKey as CNKeyDescriptor，CNContactPhoneNumbersKey as CNKeyDescriptor]） 
 
 fetchRequest.sortOrder = CNContactSortOrder.userDefault 
 
 let store = CNContactStore（）
 
 do {
 try store.enumerateContacts（with： fetchRequest，usingBlock：{（contact，stop） - > Void in 
 // print（contact.phoneNumbers.first？.value ??not found）
 
}）
} 
捕捉错误为NSError {
 print（error.localizedDescription）
} 
  

旧版
写得像这样

  fetchRequest.sortOrder = CNContactSortOrder.UserDefault 
   
 
 
 fetchRequest对象创建后
所以你的最终输出就像
 让fetchRequest = CNContactFetchRequest（keysToFetch：keysToFetch）
 
 fetchRequest.sortOrder = CNContactSortOrder.UserDefault 
 
 do {
 try store.enumerateContactsWithFetchRequest（fetchRequest，usingBlock ：{（让联系，让我们停止） - >无效
 self.contacts.append（联系人）
}）
} 
捕捉错误为NSError {
 print（error.localizedDescription）
} 
  
 
I've read official apple documentation about sorting contacts, although I am not sure how to implement it.
So, here is fetch request:
let fetchRequest = CNContactFetchRequest(keysToFetch: keysToFetch)
and my prefered sort order:
let sortOrder = CNContactSortOrder.UserDefault
and this is how I usually fetch contacts:
    do {
        try store.enumerateContactsWithFetchRequest(fetchRequest, usingBlock: { (let contact, let stop) -> Void in
                self.contacts.append(contact)
        })
    }
    catch let error as NSError {
        print(error.localizedDescription)
    }
Now what should I do with sortOrder? Where and should I include in my whole fetching process?

Updated For Swift 4.0 
let fetchRequest = CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey as CNKeyDescriptor, CNContactFamilyNameKey as CNKeyDescriptor, CNContactMiddleNameKey as CNKeyDescriptor, CNContactEmailAddressesKey as CNKeyDescriptor,CNContactPhoneNumbersKey as CNKeyDescriptor])

        fetchRequest.sortOrder = CNContactSortOrder.userDefault

        let store = CNContactStore()

        do {
            try store.enumerateContacts(with: fetchRequest, usingBlock: { (contact, stop) -> Void in
              //  print(contact.phoneNumbers.first?.value ?? "not found")

            })
        }
        catch let error as NSError {
            print(error.localizedDescription)
        }
Old Version 
write like this 
 fetchRequest.sortOrder = CNContactSortOrder.UserDefault
after fetchRequest object created 
so your final output is like 
let fetchRequest = CNContactFetchRequest(keysToFetch: keysToFetch)

fetchRequest.sortOrder = CNContactSortOrder.UserDefault

 do {
        try store.enumerateContactsWithFetchRequest(fetchRequest, usingBlock: { (let contact, let stop) -> Void in
                self.contacts.append(contact)
        })
    }
    catch let error as NSError {
        print(error.localizedDescription)
    }
