iOS获取通讯录功能

先导入AddressBook.framework先

然后引用  #import <AddressBook/AddressBook.h>

1、先授权，如果没有授权提示到设置里打开授权，如果已成功，读取通讯录数据到数组里

 addressBook = ABAddressBookCreate();

        //注册通讯录更新回调
        ABAddressBookRegisterExternalChangeCallback(addressBook, addressBookChanged, (__bridge voidvoid *)(self));

 // iOS 6
 -(bool)checkAddressBookAuthorizationStatus:(UITableView*)tableView;
 {
     //取得授权状态
     ABAuthorizationStatus authStatus =
         ABAddressBookGetAuthorizationStatus();

     if (authStatus != kABAuthorizationStatusAuthorized)
     {
         ABAddressBookRequestAccessWithCompletion
             (addressBook, ^(bool granted, CFErrorRef error)
         {
             dispatch_async(dispatch_get_main_queue(), ^{
                 if (error)
                     NSLog(@"Error: %@", (__bridge NSError *)error);
                 else if (!granted) {
                     UIAlertView *av = [[UIAlertView alloc]
                        initWithTitle:@"Authorization Denied"
                        message:@"Set permissions in Settings>General>Privacy."
                        delegate:nil
                        cancelButtonTitle:nil
                        otherButtonTitles:@"OK", nil nil];
                     [av show];
                 }
                 else
                 {
                     //还原 ABAddressBookRef
                     ABAddressBookRevert(addressBook);
                     myContacts = [NSArray arrayWithArray:
                           (__bridge_transfer NSArray*)
                           ABAddressBookCopyArrayOfAllPeople(addressBook)];
                     [tableView reloadData];
                 }
             });
         });
     }

     return authStatus == kABAuthorizationStatusAuthorized;
 }

2､如果通讯录有更新，可能及时调用回调方法，请看上面第一段代码 ABAddressBookRegisterExternalChangeCallback 方法

 - (NSInteger)numberOfSectionsInTableView:(UITableView *)tableView {
     if (nil == myContacts)
     {
         addressBook = ABAddressBookCreate();

         //注册通讯录更新回调
         ABAddressBookRegisterExternalChangeCallback(addressBook, addressBookChanged, (__bridge voidvoid *)(self));

         if ([self checkAddressBookAuthorizationStatus:tableView])
             myContacts = [NSArray arrayWithArray:(__bridge_transfer NSArray*)
                           ABAddressBookCopyArrayOfAllPeople(addressBook)];
     }
     return 1;
 }

 void addressBookChanged(ABAddressBookRef addressBook, CFDictionaryRef info, void* context)
 {
     NSLog(@"Address Book Changed");
     //__bridge               arc显式转换。 与__unsafe_unretained 关键字一样 只是引用。被代入对象的所有者需要明确对象生命周期的管理，不要出现异常访问的问题
     //__bridge_retained      类型被转换时，其对象的所有权也将被变换后变量所持有
     //__bridge_transfer      本来拥有对象所有权的变量，在类型转换后，让其释放原先所有权 就相当于__bridge_retained后，原对像执行了release操作
     RootViewController *viewController = objc_unretainedObject(context);
     //更新通讯录
     [viewController updateAddressBook];

     //注销通讯录更新回调
 //    ABAddressBookUnregisterExternalChangeCallback(addressBook, addressBookChanged, context);
 }

上面这段代码主要功能是通讯录有更新时。及时的刷新数据

3､拿出数组中的联系人数据

 NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonFirstNameProperty);
 NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue(person, kABPersonLastNameProperty);
 //用户头像
 NSData *d = (__bridge_transfer NSData*)ABPersonCopyImageData(objc_unretainedPointer([myContacts objectAtIndex:indexPath.row]));
 //取电话数据
 -(void)handleRowSelection:(int)rowIndex
 {
     ABRecordRef person = objc_unretainedPointer([myContacts objectAtIndex:rowIndex]);
     ABMultiValueRef phoneNumbers = ABRecordCopyValue(person,
                                                      kABPersonPhoneProperty);

     if (ABMultiValueGetCount(phoneNumbers) == 1)
         [self callThisNumber:(__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, 0)];
     else if (ABMultiValueGetCount(phoneNumbers) > 1)
     {
         UIAlertView *av = [[UIAlertView alloc] initWithTitle:@"Pick A Number"
                                                       message:@"Which number would you like to call?"
                                                      delegate:self
                                             cancelButtonTitle:@"Cancel"
                                             otherButtonTitles:nil];

         for (int i=0; i < ABMultiValueGetCount(phoneNumbers); i++)
             [av addButtonWithTitle:(__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, i)];

         [av show];
     }

     if (phoneNumbers)
         CFRelease(phoneNumbers);
 }

4、删除通讯录数据

 <span style="white-space:pre">    </span>ABRecordRef person = objc_unretainedPointer([myContacts objectAtIndex:indexPath.row]);
         CFErrorRef *error;
         ABAddressBookRemoveRecord(addressBook, person, error);
         ABAddressBookSave(addressBook, error);
         myContacts = nil;
         [tableView deleteRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade];
