iOS ContactsUI(联系人)

1. 带UI的通讯录

#import "ViewController.h" #import <AddressBookUI/AddressBookUI.h> @interface ViewController ()<ABPeoplePickerNavigationControllerDelegate> @end @implementation ViewController // 触摸显示 - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { //1. 创建联系人选择控制器 ABPeoplePickerNavigationController *picker = [ABPeoplePickerNavigationController new]; //2. 设置代理 --> 注意不是 Delegate picker.peoplePickerDelegate = self; //3. 模态视图弹出 [self presentViewController:picker animated:YES completion:nil]; } #pragma mark 选中某个联系人时调用 /** 以下两个方法,如果同时实现, 只会运行didSelectPerson: 方法 两个方法, 应该实现一个即可 */ - (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person { //需求: 获取姓名 和 电话 //1. 获取姓名 //Record --> 就相当于一条记录 //lastName: 姓 CFStringRef lastName = ABRecordCopyValue(person, kABPersonLastNameProperty); NSString *lastNameStr = (__bridge NSString *)(lastName); NSLog(@"lastNameStr: %@",lastNameStr); CFStringRef firstName = ABRecordCopyValue(person, kABPersonFirstNameProperty); NSString *firstNameStr = (__bridge NSString *)(firstName); NSLog(@"firstNameStr: %@",firstNameStr); CFRelease(lastName); CFRelease(firstName); //2. 获取电话 --> 电话是多数据类型 ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty); //2.1 获取电话的个数 CFIndex count = ABMultiValueGetCount(phones); //2.2 遍历联系人 for (CFIndex i = 0 ; i < count; i++) { //2.3 获取联系电话的标签 NSString *label = (__bridge_transfer NSString *)ABMultiValueCopyLabelAtIndex(phones, i); NSLog(@"label: %@",label); //2.4 获取联系电话 NSString *value = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phones, i)); NSLog(@"value: %@",value); } //3. 释放 CF 对象 CFRelease(phones); //Core Foundation 和 Fundation 桥接的问题 --> 面试题 //1. 有几种方式 2. 注意事项 注意释放 CF 对象 //将 CF 对象给 Foundatian //1. (__bridge type)<#expression#>) : 只是让 Foundation 框架暂时使用 CF 框架对象 //2. (__bridge_transfer )) / CFBridgingRelease : CF框架移交对象的管理权给 Foundation 框架 //将 Foundatian给 CF 对象 不常用 //3. (__bridge_retained <#CF type#>)<#expression#>) } #pragma mark 选中联系人的某个属性的时候调用 //- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController *)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier //{ // NSLog(@"%d",property); //} #pragma mark 取消选中联系人时调用 // 在 iOS7下, 必须实现此方法, 否则就会崩溃 //- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker //{ // NSLog(@"%s",__func__); //} @end 

2. 不带UI的通讯录

1). AppDelegate授权

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { //通讯录授权 --> iOS6开始, 必须授权才能上架 /** kABAuthorizationStatusNotDetermined = 0 用户未选择 kABAuthorizationStatusRestricted, 一些许可配置阻止了通讯录的交互 kABAuthorizationStatusDenied, 用户拒绝 kABAuthorizationStatusAuthorized 用户授权 */ //1. 获取授权状态 ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus(); //2. 创建 AddrssBook ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL); //3. 没有授权时就授权 if (status == kABAuthorizationStatusNotDetermined) { ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) { //3.1 判断出错 if (error) { return; } //3.2 判断是否授权 if (granted) { NSLog(@"已经授权"); } else { NSLog(@"没有授权"); } }); } //4. 释放 CF 对象 CFRelease(addressBook); return YES; } 

2). 代码

#import "ViewController.h" #import <AddressBook/AddressBook.h> @implementation ViewController // 触摸显示 - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { // 点击屏幕获取所有联系人信息 //1. 判断是否授权成功, 授权成功才能获取数据 if ( ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) { //2. 创建通讯录 ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, NULL); //3. 获取联系人 --> Array CFArrayRef peosons = ABAddressBookCopyArrayOfAllPeople(addressBook); //4. 遍历联系人来获取数据(姓名和电话) CFIndex count = CFArrayGetCount(peosons); for (CFIndex i = 0 ; i < count; i++) { //5. 获取单个联系人 ABRecordRef person = CFArrayGetValueAtIndex(peosons, i); //6. 获取姓名 NSString *lastName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonLastNameProperty)); NSString *firstName = CFBridgingRelease(ABRecordCopyValue(person, kABPersonFirstNameProperty)); NSLog(@"lastName: %@, firstName: %@", lastName, firstName); //7. 获取电话 ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty); //7.1 获取 count CFIndex phoneCount = ABMultiValueGetCount(phones); //7.2 遍历ABMultiValueRef for (CFIndex i = 0; i < phoneCount; i++) { NSString *label = CFBridgingRelease(ABMultiValueCopyLabelAtIndex(phones, i)); NSString *value = CFBridgingRelease(ABMultiValueCopyValueAtIndex(phones, i)); NSLog(@"label: %@, value: %@",label, value); } NSLog(@"\n\n"); //8.1 释放 CF 对象 CFRelease(phones); } //8.1 释放 CF 对象 CFRelease(peosons); CFRelease(addressBook); } } @end 

3. iOS9 通讯录(新增)

#import "ViewController.h" #import <ContactsUI/ContactsUI.h> @interface ViewController () <CNContactPickerDelegate> @end @implementation ViewController - (void)touchesBegan:(NSSet<UITouch *> *)touches withEvent:(UIEvent *)event { // 1. 创建控制器 CNContactPickerViewController *contact = [CNContactPickerViewController new]; // 2. 设置代理 contact.delegate = self; // 3. 模态弹出 [self presentViewController:contact animated:YES completion:nil]; } #pragma mark 选择联系人的时候调用 - (void)contactPicker:(CNContactPickerViewController *)picker didSelectContact:(CNContact *)contact { // 1. 获取姓名 NSLog(@"givenName: %@, familyName: %@", contact.givenName, contact.familyName); // 2. 获取电话 for (CNLabeledValue *labeledValue in contact.phoneNumbers) { CNPhoneNumber *phoneNumber = labeledValue.value; NSLog(@"phoneNumber: %@", phoneNumber.stringValue); } } #pragma mark 实现了此方法就可以选择多个联系人 - (void)contactPicker:(CNContactPickerViewController *)picker didSelectContacts:(NSArray<CNContact *> *)contacts { for (CNContact *contact in contacts) { NSLog(@"givenName: %@, familyName: %@", contact.givenName, contact.familyName); for (CNLabeledValue *labeledValue in contact.phoneNumbers) { NSLog(@"label: %@", labeledValue.label); CNPhoneNumber *phoneNumber = labeledValue.value; NSLog(@"phoneNumber: %@", phoneNumber.stringValue); } } } @end
