IOS 通讯录的访问和修改的实现

IOS 通讯录的访问和修改的实现

在iOS端可以通过AddressBook或者AddressBookUI两个框架实现，区别是第二个框架带视图，一般使用第一个框架就够了。
下面介绍AddressBook框架的使用，注意这个是C语言框架，使用起来比较麻烦。

①请求授权

先判断授权状态，如果未授权则进行授权。

// 1.主动请求授权，先判断授权状态
NSInteger state = ABAddressBookGetAuthorizationStatus();
if (state == kABAuthorizationStatusAuthorized) {
  NSLog(@"已经授权");
}else{
  ABAddressBookRef book = ABAddressBookCreateWithOptions(NULL, NULL);
  ABAddressBookRequestAccessWithCompletion(book, ^(bool granted, CFErrorRef error) {
    if (granted) {
      NSLog(@"授权成功");
    }else{
      NSLog(@"授权失败");
    }
  });
}

②获取通讯录的联系人

c语言没有对象，通过一些以Ref结尾的指针来获取数据。

注意C语言数组的规模通过函数获取，拿到元素也要通过函数。

注意一些枚举值以k开头。

注意电话是一个数组。

// 先判断授权状态
if (ABAddressBookGetAuthorizationStatus() != kABAuthorizationStatusAuthorized) {
  NSLog(@"未授权");
  return;
} 

ABAddressBookRef book = ABAddressBookCreateWithOptions(NULL, NULL);
CFArrayRef persons = ABAddressBookCopyArrayOfAllPeople(book);
CFIndex count = CFArrayGetCount(persons);
for (NSInteger i = 0; i < count; i++) {
  ABRecordRef person = CFArrayGetValueAtIndex(persons, i);
  CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
  CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
  ABMutableMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
  NSLog(@"联系人:%@ %@",lastName,firstName);
  NSInteger cnt = ABMultiValueGetCount(phones);
  for (int j = 0; j < cnt; j++) {
    CFStringRef phone = ABMultiValueCopyValueAtIndex(phones, j);
    NSLog(@"电话：%@ ",phone);
  }
}

③修改通讯录联系人

首先拿到通讯录中的人，然后调用SetValue方法来修改值。

最后不要忘记保存。

// 先判断授权状态
if (ABAddressBookGetAuthorizationStatus() != kABAuthorizationStatusAuthorized) {
  NSLog(@"未授权");
  return;
} 

ABAddressBookRef book = ABAddressBookCreateWithOptions(NULL, NULL);
CFArrayRef persons = ABAddressBookCopyArrayOfAllPeople(book);
ABRecordRef person = CFArrayGetValueAtIndex(persons, 0);
ABRecordSetValue(person, kABPersonLastNameProperty, @"changed", NULL);
ABAddressBookSave(book, NULL);

④添加一个联系人

注意添加电话时应创建MultiValue。

// 先判断授权状态
if (ABAddressBookGetAuthorizationStatus() != kABAuthorizationStatusAuthorized) {
  NSLog(@"未授权");
  return;
} 

ABAddressBookRef book = ABAddressBookCreateWithOptions(NULL, NULL);
CFArrayRef persons = ABAddressBookCopyArrayOfAllPeople(book);
CFIndex count = CFArrayGetCount(persons);
for (NSInteger i = 0; i < count; i++) {
  ABRecordRef person = CFArrayGetValueAtIndex(persons, i);
  CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty);
  CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty);
  ABMutableMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
  NSLog(@"联系人:%@ %@",lastName,firstName);
  NSInteger cnt = ABMultiValueGetCount(phones);
  for (int j = 0; j < cnt; j++) {
    CFStringRef phone = ABMultiValueCopyValueAtIndex(phones, j);
    NSLog(@"电话：%@ ",phone);
  }
}
