ios - 从地址簿中获取人数并将其与 Parse DB 进行比较

Question

今天发现了一个问题。

我正在使用 DigitsKit + Parse、用于用户真实验证的 DigitsKit 和 Parse 作为有用的框架，以便为用户和我提供轻松的 sinUp、登录等。

下面是它的工作原理：

1. 用户在 textField 中输入他们的电话号码和密码

2. 在 DigitsKit 使用 SMS 和短代码验证之后，该用户是真实的，短信来到 USER 并且他/她在验证文本字段中输入它。如果一切正常 -> 用户名和密码以 PFUser 身份存储在 Parse DB 中。

   用户名（在 ParseDB 中）= 用户的移动电话（在 textField 中）

3. 在注册和登录后，用户在新视图上按下“FindFriends”按钮，这里应该是好友搜索系统，但我在这里遇到了问题......请看下面的控制器案例：

   import UIKit
   import SwiftAddressBook
   import AddressBook
   import Parse
   
   class FriendsViewController: UIViewController {
   let status : ABAuthorizationStatus = SwiftAddressBook.authorizationStatus()
   
       var addrssbk : ABAddressBook!
   var addressBook: SwiftAddressBook? = swiftAddressBook
   
   
   override func viewDidLoad() {
       super.viewDidLoad()
       GetContactNumbers()
             }
   
   
   
   override func viewDidAppear(animated: Bool) {
   
   
   }
   
   
   
   
   
   
   func createAddressBook() -> Bool {
   if self.addressBook != nil {
       return true
   }
   var err : Unmanaged<CFError>? = nil
   let addrssbk : ABAddressBook? = ABAddressBookCreateWithOptions(nil, &err).takeRetainedValue()
   if addrssbk == nil {
       println(err)
       self.addressBook = nil
       return false
   }
   self.addrssbk = addrssbk
   return true
   }
   
      func determineStatus() -> Bool {
   let status = ABAddressBookGetAuthorizationStatus()
   switch status {
   case .Authorized:
       return self.createAddressBook()
   case .NotDetermined:
       var ok = false
       ABAddressBookRequestAccessWithCompletion(nil) {
           (granted:Bool, err:CFError!) in
           dispatch_async(dispatch_get_main_queue()) {
               if granted {
                   ok = self.createAddressBook()
               }
           }
       }
       if ok == true {
           return true
       }
       self.addressBook = nil
       return false
   case .Restricted:
       self.addressBook = nil
       return false
   case .Denied:
       self.addressBook = nil
       return false
   }
   }
   
   
   func GetContactNumbers() {
   
   swiftAddressBook?.requestAccessWithCompletion({ (success, error) -> Void in
       if success {
           if let people = swiftAddressBook?.allPeople {
               for person in people {
                   if let numbers = person.phoneNumbers {
                           let names = person.compositeName
                      NSLog("%@", numbers.map( {$0.value} ))
                      NSLog("%@", names!)
   
   
   
                      if let query = PFUser.query() {
   
                          query.whereKey("username", equalTo: "\(person.phoneNumbers)")
                          var friends = query.findObjects()
                          println(friends)
                       }
   
   
   
                   //the value entry of the multivalue struct contains the data
   
                   }
               }
           }
           //do something with swiftAddressBook
   
       }else {
           //no success. Optionally evaluate error
        }
   })
   
   
   }
   
   
   
   override func didReceiveMemoryWarning() {
       super.didReceiveMemoryWarning()
       // Dispose of any resources that can be recreated.
   }
   
   
   
   }
   

我不能将每个电话号码与 ParseDB 中的用户名进行比较，有什么建议我应该怎么做？或任何命中/解决方案？

PS，我在数组、字典和其他数组/键值类型的数据和循环方面也遇到了麻烦，所以任何帮助都是完美的

解决了使用 map 和 stringFormation 的问题：

   func GetContactNumbers() {

        let query = PFUser.query()

        swiftAddressBook?.requestAccessWithCompletion({ (success, error) -> Void in
            if success {
                if let people = swiftAddressBook?.allPeople {
                    for person in people {
                        if let numbers = person.phoneNumbers {
                           let names = person.compositeName
                            let formatednumbers = numbers.map { $0.value.componentsSeparatedByCharactersInSet(NSCharacterSet.decimalDigitCharacterSet().invertedSet).reduce("", combine: {$0+$1})}
//                            NSLog("%@", numbers.map( {$0.value} ))
                            NSLog("%@", names!)
                            println(formatednumbers)
                            query!.whereKey("username", equalTo: "\(formatednumbers)")

                            if let friends = query!.findObjects() {
                                println(friends)

                            }





                        //the value entry of the multivalue struct contains the data

                        }
                    }
                }
                //do something with swiftAddressBook

            }else {
                //no success. Optionally evaluate error
             }
        })


    }
