上一篇文章已经介绍了关于AddressBookUI.framework框架访问通讯的方法,这种方法是有界面展示到用户面前的,而今天要说的AddressBook.framework是没有界面的,即我们是只能获得所需要的数据,然后需要自己创建一个View,将获得的用户的信息展示到用户面前.
利用AddressBook.framework访问用户的通讯录达到时候,首先需要用户进行授权,如果用户已经同意,才可以访问用户的通讯录信息:
让用户授权需要在AppDelegate里面实现 :
#import "AppDelegate.h"
#import <AddressBook/AddressBook.h>
@interface AppDelegate ()
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// 1.获取授权的状态
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
// 2.判断授权状态,如果是未决定状态,才需要请求
if (status == kABAuthorizationStatusNotDetermined) {
// 2.1.创建通信录对象
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
// 2.2.请求授权
ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
if (granted) {
NSLog(@"授权成功");
} else {
NSLog(@"授权失败");
}
});
}
return YES;
}
关于授权码的介绍如下
kABAuthorizationStatusNotDetermined
用户还没有决定是否授权你的程序进行访问
kABAuthorizationStatusRestricted
iOS设备上一些许可配置阻止程序与通讯录数据库进行交互
kABAuthorizationStatusDenied
用户明确的拒绝了你的程序对通讯录的访问
kABAuthorizationStatusAuthorized
用户已经授权给你的程序对通讯录进行访问
在完成授权以后,在进行访问用户的通讯录,代码如下:
#import "ViewController.h"
#import <AddressBook/AddressBook.h>
@interface ViewController ()
@end
@implementation ViewController
- (void)viewDidLoad {
[super viewDidLoad];
}
- (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event
{
// 1.获取授权的状态
ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();
// 2.如果用户已经授权
if (status != kABAuthorizationStatusAuthorized) return;
// 3.创建通信录对象
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL);
// 4.从通信录对象中,将所有的联系人拷贝出来
CFArrayRef peopleArray = ABAddressBookCopyArrayOfAllPeople(addressBook);
// 5.遍历所有的联系人(每一个联系人都是一条记录)
CFIndex peopleCount = CFArrayGetCount(peopleArray);
for (CFIndex i = 0; i < peopleCount; i++) {
// 6.获取到联系人
ABRecordRef person = CFArrayGetValueAtIndex(peopleArray, i);
// 7.获取姓名
NSString *lastname = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
NSLog(@"%@ %@", lastname, firstName);
}
// 8.释放不再使用的对象
CFRelease(peopleArray);
CFRelease(addressBook);
}
