有时候APP需要用户输入一位联系人的姓名和电话，除了用户手动输入，一般也允许用户从通讯录中选择一位联系人（图1），下面的代码就是使用系统的<AddressBookUI/AddressBookUI.h>库实现这一需求。

#import "ViewController.h"#import <AddressBookUI/AddressBookUI.h>@interface ViewController ()<ABPeoplePickerNavigationControllerDelegate>@property (weak, nonatomic) IBOutlet UITextField *nameTextField;@property (weak, nonatomic) IBOutlet UITextField *phoneTextField;@end@implementation ViewController- (void)viewDidLoad {    [super viewDidLoad];}//用户点击选择按钮- (IBAction)clickSelect:(UIButton *)sender {    ABPeoplePickerNavigationController *picker =[[ABPeoplePickerNavigationController alloc] init];    picker.peoplePickerDelegate = self;    [self presentViewController:picker animated:YES completion:nil];}//这个方法在用户取消选择时调用- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker{    [self dismissViewControllerAnimated:YES completion:^{}];}//这个方法在用户选择一个联系人后调用-(void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person{    [self displayPerson:person];    [self dismissViewControllerAnimated:YES completion:^{}];}//获得选中person的信息- (void)displayPerson:(ABRecordRef)person{    NSString *firstName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonFirstNameProperty);    NSString *middleName = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonMiddleNameProperty);    NSString *lastname = (__bridge_transfer NSString*)ABRecordCopyValue(person, kABPersonLastNameProperty);    NSMutableString *nameStr = [NSMutableString string];    if (lastname!=nil) {        [nameStr appendString:lastname];    }    if (middleName!=nil) {        [nameStr appendString:middleName];    }    if (firstName!=nil) {        [nameStr appendString:firstName];    }        NSString* phone = nil;    ABMultiValueRef phoneNumbers = ABRecordCopyValue(person,kABPersonPhoneProperty);    if (ABMultiValueGetCount(phoneNumbers) > 0) {        phone = (__bridge_transfer NSString*)ABMultiValueCopyValueAtIndex(phoneNumbers, 0);    } else {        phone = @"[None]";    }        //可以把-、+86、空格这些过滤掉    NSString *phoneStr = [phone stringByReplacingOccurrencesOfString:@"-" withString:@""];    phoneStr = [phoneStr stringByReplacingOccurrencesOfString:@"+86" withString:@""];    phoneStr = [phoneStr stringByReplacingOccurrencesOfString:@" " withString:@""];        [self.nameTextField setText:nameStr];    [self.phoneTextField setText:phoneStr];}@end
