獲取通訊錄-AddressBook(swift)

1. 導入框架

   import AddressBook
   

2. 實現步驟及代碼

   override func viewDidLoad() {
           super.viewDidLoad()
   
           // 1. 獲取當前的授權狀態,
           let status = ABAddressBookGetAuthorizationStatus()
           if status ==  .NotDetermined {
   
               // 2. 如果當前沒有授權, 應該請求授權
               // 參數1: 通訊錄對象
               // 參數2: 回調block , 里面包含了請求的結果
               let book = ABAddressBookCreate().takeRetainedValue()
               ABAddressBookRequestAccessWithCompletion(book, { (granted: Bool, error: CFError!) in
                   if granted {
                       print("授權成功")
                   }else {
                       print("授權失敗")
                   }
               })
           }
       }
   
   override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
   
       // 0. 驗證授權狀態
        let status = ABAddressBookGetAuthorizationStatus()
       if status != .Authorized {
           print("沒有權限")
           return
       }
   
       // 1. 獲取所有的聯系人信息
       let book  = ABAddressBookCreate().takeRetainedValue()
       let array = ABAddressBookCopyArrayOfAllPeople(book).takeRetainedValue()
   
       // 2. 遍歷每一個聯系人
       // CFArray, 遍歷這樣的數組, 應該, 先取出所有的個數, 然后使用響應的函數, 獲取里面每一個元素
       let count = CFArrayGetCount(array)
       for i in 0..<count {
   
           // 里面每一個對象, 都是一個聯系人記錄 ABRecord\
           // UnsafePointer<Void> == void * : 指向任意對象的指針
           // swift 對于這種對象, 有個專門的函數
           // 注意事項: 必須明確的恩知道, 目標到底是什么類型
   
           let personP = CFArrayGetValueAtIndex(array, i)
           let person = unsafeBitCast(personP, ABRecord.self)
   
           // 獲取姓名
           let firsName = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as! String
           let lastName = ABRecordCopyValue(person, kABPersonLastNameProperty).takeRetainedValue() as! String
           print(firsName, lastName)
   
           // 獲取電話號碼(復雜屬性, 多值)
           let multiValue = ABRecordCopyValue(person, kABPersonPhoneProperty).takeRetainedValue() as ABMultiValueRef
   
           // 遍歷電話號碼
           let num = ABMultiValueGetCount(multiValue)
           for j in 0..<num {
   
               // 電話號碼 = 標簽 + 值
               let label = ABMultiValueCopyLabelAtIndex(multiValue, j).takeRetainedValue()
               let value = ABMultiValueCopyValueAtIndex(multiValue, j).takeRetainedValue() as! String
   
               print(label, value)
           }
       }
   }
