这篇文章给大家分享的是有关iOS如何实现从通讯录中选择联系人的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
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];
}
