這篇文章給大家分享的是有關iOS如何實現從通訊錄中選擇聯系人的內容。小編覺得挺實用的,因此分享給大家做個參考,一起跟隨小編過來看看吧。
有時候APP需要用戶輸入一位聯系人的姓名和電話,除了用戶手動輸入,一般也允許用戶從通訊錄中選擇一位聯系人(圖1),下面的代碼就是使用系統的<AddressBookUI/AddressBookUI.h>庫實現這一需求。

完整代碼:
#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]; } //用戶點擊選擇按鈕 - (IBAction)clickSelect:(UIButton *)sender { ABPeoplePickerNavigationController *picker =[[ABPeoplePickerNavigationController alloc] init]; picker.peoplePickerDelegate = self; [self presentViewController:picker animated:YES completion:nil]; } //這個方法在用戶取消選擇時調用 - (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker { [self dismissViewControllerAnimated:YES completion:^{}]; } //這個方法在用戶選擇一個聯系人后調用 -(void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person{ [self displayPerson:person]; [self dismissViewControllerAnimated:YES completion:^{}]; } //獲得選中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、空格這些過濾掉 NSString *phoneStr = [phone stringByReplacingOccurrencesOfString:@"-" withString:@""]; phoneStr = [phoneStr stringByReplacingOccurrencesOfString:@"+86" withString:@""]; phoneStr = [phoneStr stringByReplacingOccurrencesOfString:@" " withString:@""]; [self.nameTextField setText:nameStr]; [self.phoneTextField setText:phoneStr]; } @end
