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);
}
}
