## iOS：ABPeoplePickerNavigationController系统通讯录使用 昨天因项目需求要访问系统通讯录获取电话号码，于是乎从一无所知，开始倒腾，倒腾了一下午，总算了弄好了。写这边博客是为了记录一下，自己下一次弄的时候就别在出错了。同时，有和我一样的菜鸟能够避免走一下弯路。 好了，言归正传，要访问系统的通讯录，首先需要添加`AddressBook.framework` 和 `AddressBookUI.framework` 两个框架到你工程中build phase的"Link Binary With Libraries"之下，然后就可以开始了。 首先我们需要创建一个控制器：ViewController，在.h文件中导入头文件：<AddressBook/AddressBook.h>、  <AddressBookUI/AddressBookUI.h>， ~~~ #import <AddressBook/AddressBook.h> #import <AddressBookUI/AddressBookUI.h> ~~~ 然后在控制器实现 ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate协议 ~~~ @interface ViewController ()<ABPeoplePickerNavigationControllerDelegate, UINavigationControllerDelegate> ~~~ 在viewDidAppear方法中创建ABPeoplePickerNavigationController，同时设置viewController作为委托对象 ~~~ - (void)viewDidAppear:(BOOL)animated { [super viewDidAppear:animated]; ABPeoplePickerNavigationController *pNC = [[ABPeoplePickerNavigationController alloc] init]; pNC.peoplePickerDelegate = self; [self presentViewController:pNC animated:YES completion:nil]; } ~~~ 接下来需要实现ABPeoplePickerNavigationControllerDelegate协议 ~~~ #pragma mark - ABPeoplePickerNavigationControllerDelegate - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier { ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty); long index = ABMultiValueGetIndexForIdentifier(phone,identifier); NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index); phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""]; NSLog(@"%@", phoneNO); if (phone && phoneNO.length == 11) { [peoplePicker dismissViewControllerAnimated:YES completion:nil]; return; }else{ UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"错误提示" message:@"请选择正确手机号" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alertView show]; } } - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person NS_AVAILABLE_IOS(8_0) { ABPersonViewController *personViewController = [[ABPersonViewController alloc] init]; personViewController.displayedPerson = person; [peoplePicker pushViewController:personViewController animated:YES]; } - (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker { [peoplePicker dismissViewControllerAnimated:YES completion:nil]; } - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person NS_DEPRECATED_IOS(2_0, 8_0) { return YES; } - (BOOL)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker shouldContinueAfterSelectingPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier NS_DEPRECATED_IOS(2_0, 8_0) { ABMultiValueRef phone = ABRecordCopyValue(person, kABPersonPhoneProperty); long index = ABMultiValueGetIndexForIdentifier(phone,identifier); NSString *phoneNO = (__bridge NSString *)ABMultiValueCopyValueAtIndex(phone, index); phoneNO = [phoneNO stringByReplacingOccurrencesOfString:@"-" withString:@""]; NSLog(@"%@", phoneNO); if (phone && phoneNO.length == 11) { [peoplePicker dismissViewControllerAnimated:YES completion:nil]; return NO; }else{ UIAlertView *alertView = [[UIAlertView alloc] initWithTitle:@"错误提示" message:@"请选择正确手机号" delegate:self cancelButtonTitle:@"确定" otherButtonTitles:nil]; [alertView show]; } return YES; }@end ~~~ 到这里本以为大功告成，的确在iOS7是没有任何问题，但是iOS8出现了坑爹的问题，就是选择联系人后 ABPeoplePickerNavigationController会自动dismiss掉，这个问题可坑坏我了。问了谷歌和度娘，在stackvoerflow找到了类似的问题，但是都没有得到解决，在觉得没有办法的时候，又开始看ABPeoplePickerNavigationController.h的头文件，发现了 predicateForSelectionOfPerson属性，于是乎在viewDidAppear方法中加入如下代码： ~~~ if([[UIDevice currentDevice].systemVersion floatValue] >= 8.0){ pNC.predicateForSelectionOfPerson = [NSPredicate predicateWithValue:false]; } ~~~ 运行程序，大功告成
