（1）导入ABAddressBook库，然后添加头文件后，就可以使用。

——因为这个库的方法基本是C语言的风格，所以类基本是以CF开头的，比如CFStringRef以及CFArrayRef，它和OC的NSString和NSArray类似，可以相互转换，利用__bridge来强制转换，如(__bridge NSString *)XXX，就可以把原本是CFStringRef的XXX转换成NSString类型，这样做的好处就是不需要在很多地方进行释放操作CFRelease()。

——使用通讯录，首先需要发送访问请求，得到请求后，才可以进行一系列操作，访问请求的方法是ABAddressBookRequestAccessWithCompletion，而建议在后续执行一些通讯录操作前可以判断此时我们访问的授权是否还存在，如果用户更改了授权，我们就不必进一步操作，而判断的方法是：

//点击之前，先判断是否被允许
if (ABAddressBookGetAuthorizationStatus()!=kABAuthorizationStatusAuthorized) return;

//保存
ABAddressBookSave(bookRef, NULL);

——删除操作是：

ABAddressBookRemoveRecord(bookRef, people, NULL);

主要代码如下：

#import "ViewController.h"
#import <AddressBook/AddressBook.h>

@interface ViewController ()

@end
