获取通讯录-AddressBook(swift)

获取通讯录-AddressBook(swift)

1. 导入框架

   import AddressBook
   

2. 实现步骤及代码

   override func viewDidLoad() {
           super.viewDidLoad()
   
           // 1. 获取当前的授权状态,
           let status = ABAddressBookGetAuthorizationStatus()
           if status ==  .NotDetermined {
   
               // 2. 如果当前没有授权, 应该请求授权
               // 参数1: 通讯录对象
               // 参数2: 回调block , 里面包含了请求的结果
               let book = ABAddressBookCreate().takeRetainedValue()
               ABAddressBookRequestAccessWithCompletion(book, { (granted: Bool, error: CFError!) in
                   if granted {
                       print("授权成功")
                   }else {
                       print("授权失败")
                   }
               })
           }
       }
   
   override func touchesBegan(touches: Set<UITouch>, withEvent event: UIEvent?) {
   
       // 0. 验证授权状态
        let status = ABAddressBookGetAuthorizationStatus()
       if status != .Authorized {
           print("没有权限")
           return
       }
   
       // 1. 获取所有的联系人信息
       let book  = ABAddressBookCreate().takeRetainedValue()
       let array = ABAddressBookCopyArrayOfAllPeople(book).takeRetainedValue()
   
       // 2. 遍历每一个联系人
       // CFArray, 遍历这样的数组, 应该, 先取出所有的个数, 然后使用响应的函数, 获取里面每一个元素
       let count = CFArrayGetCount(array)
       for i in 0..<count {
   
           // 里面每一个对象, 都是一个联系人记录 ABRecord\
           // UnsafePointer<Void> == void * : 指向任意对象的指针
           // swift 对于这种对象, 有个专门的函数
           // 注意事项: 必须明确的恩知道, 目标到底是什么类型
   
           let personP = CFArrayGetValueAtIndex(array, i)
           let person = unsafeBitCast(personP, ABRecord.self)
   
           // 获取姓名
           let firsName = ABRecordCopyValue(person, kABPersonFirstNameProperty).takeRetainedValue() as! String
           let lastName = ABRecordCopyValue(person, kABPersonLastNameProperty).takeRetainedValue() as! String
           print(firsName, lastName)
   
           // 获取电话号码(复杂属性, 多值)
           let multiValue = ABRecordCopyValue(person, kABPersonPhoneProperty).takeRetainedValue() as ABMultiValueRef
   
           // 遍历电话号码
           let num = ABMultiValueGetCount(multiValue)
           for j in 0..<num {
   
               // 电话号码 = 标签 + 值
               let label = ABMultiValueCopyLabelAtIndex(multiValue, j).takeRetainedValue()
               let value = ABMultiValueCopyValueAtIndex(multiValue, j).takeRetainedValue() as! String
   
               print(label, value)
           }
       }
   }
