iOS从通讯录中选择联系人

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。

图1

完整代码：

#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
