在项目中有的地方会用到获取通讯里面的某个联系人的联系方式，这里我们稍微封装一下这个方法。

第一步：我们需要获取通讯录权限

在info.plist文件中，添加 key ： Privacy - Contacts Usage Description，value：方便用户从通讯录选取要保存的号码，如下图：

1、新建一个ContactManager类

添加两个Block，用于回调权限和联系人号码

/** * 通讯录权限Block * * @param isAuthorization 是否有权限；  YES：有权限；   NO：无权限 */typedef void(^AddressBookAuthorization)(BOOL isAuthorization);/** * 通讯录号码Block * * @param phoneNumber 号码 */typedef void(^AddressBookOfPhoneNumberBlock)(NSString *phoneNumber);

添加两个方法，用于获取权限和弹出通讯录列表

/** * 模态弹出通讯录列表页 * * @param addressBookOfPhoneNumber block */- (void)presentAddressBookViewControllerWithPhoneNumber:(AddressBookOfPhoneNumberBlock)addressBookOfPhoneNumber;/** * 获取通讯录权限方法，可以单独使用 * * @param contactAuthorization block */- (void)getAddressBookAuthorization:(AddressBookAuthorization)contactAuthorization;

2、获取通讯录权限问题

获取通讯录权限的时候，判断系统版本，当veision >= 9.0 时，使用CNAuthorizationStatus；否则使用ABAuthorizationStatus。

- (void)getAddressBookAuthorization:(AddressBookAuthorization)contactAuthorization{
       NSString *version = [UIDevice currentDevice].systemVersion;    if (version.doubleValue >= 9.0) {
           CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];        if (status == CNAuthorizationStatusNotDetermined) {
               CNContactStore *store = [[CNContactStore alloc] init];            [store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
                   //第一次获取权限判断，点击 “不允许” 则 granted = NO；点击 “好” 则 granted = YES；                contactAuthorization(granted);            }];        } else if (status == CNAuthorizationStatusAuthorized) {
   //有权限            contactAuthorization(YES);        } else {
   //无权限            //NSLog(@"iOS 9 later 您未开启通讯录权限,请前往设置中心开启");            contactAuthorization(NO);        }    } else {
           ABAddressBookRef bookref = ABAddressBookCreateWithOptions(NULL, NULL);        ABAuthorizationStatus status = ABAddressBookGetAuthorizationStatus();        if (status == kABAuthorizationStatusNotDetermined) {
               ABAddressBookRequestAccessWithCompletion(bookref, ^(bool granted, CFErrorRef error) {
                   contactAuthorization(granted);            });        }        if (status == kABAuthorizationStatusAuthorized) {
               contactAuthorization(YES);        }else{
               //NSLog(@"iOS 9 before 您未开启通讯录权限,请前往设置中心开启");            contactAuthorization(NO);        }    }}

3、调起通讯录列表页

获取通讯录列表的时候，同样判断系统版本，当veision >= 9.0 时，使用CNContactPickerViewController；否则使用ABPeoplePickerNavigationController。

- (void)presentAddressBookViewControllerWithPhoneNumber:(AddressBookOfPhoneNumberBlock)addressBookOfPhoneNumber{
       [self getAddressBookAuthorization:^(BOOL isAuthorization) {
           if (isAuthorization) {
               [self presentABPeoplePickerOrCNContactPickerControllerWithPhoneNumber:addressBookOfPhoneNumber];        } else {
               [self setContactAuthorization];        }    }];}

- (void)presentABPeoplePickerOrCNContactPickerControllerWithPhoneNumber:(AddressBookOfPhoneNumberBlock)phoneNumberBlock{
       NSString *version = [UIDevice currentDevice].systemVersion;    //主线程刷新UI    dispatch_async(dispatch_get_main_queue(), ^{
                   self.phoneNumberBlock = phoneNumberBlock;                if (version.doubleValue >= 9.0) {
               //iOS 9 之后            CNContactPickerViewController *picker = [[CNContactPickerViewController alloc] init];            picker.delegate = self;            //picker.predicateForSelectionOfContact = [NSPredicate predicateWithFormat:@"emailAddresses.@count == 1"];            //picker.predicateForEnablingContact = [NSPredicate predicateWithFormat:@"emailAddresses.@count > 0"];            //picker.predicateForSelectionOfProperty = [NSPredicate predicateWithFormat:@"(key == 'emailAddresses') AND (value LIKE '*@mac.com')"];            picker.displayedPropertyKeys = @[CNContactPhoneNumbersKey];//只显示手机号            [KeyWidow.rootViewController presentViewController:picker animated:YES completion:nil];        } else {
               //iOS 9 之前            ABPeoplePickerNavigationController *picker = [ABPeoplePickerNavigationController new];            picker.peoplePickerDelegate = self;            picker.displayedProperties = @[[NSNumber numberWithInt:kABPersonPhoneProperty]];            [KeyWidow.rootViewController presentViewController:picker animated:YES completion:nil];        }            });}

4、代理方法回调

#pragma mark - CNContactPickerDelegate- (void)contactPickerDidCancel:(CNContactPickerViewController *)picker{
       [picker dismissViewControllerAnimated:YES completion:nil];}- (void)contactPicker:(CNContactPickerViewController *)picker didSelectContactProperty:(CNContactProperty *)contactProperty;{
       //注意：这里和displayedPropertyKeys属性设置相对应；只有 CNPhoneNumber 类型，如果添加别的类型，需要加类型判断，否则可能crash；例如：通讯录中的日期、邮箱...    CNPhoneNumber *phoneNumber = contactProperty.value;    NSString *phoneStr = phoneNumber.stringValue;    //回调block，把号码带回去    if (self.phoneNumberBlock) {
           self.phoneNumberBlock(phoneStr);    }}#pragma mark - ABPeoplePickerNavigationControllerDelegate- (void)peoplePickerNavigationControllerDidCancel:(ABPeoplePickerNavigationController *)peoplePicker{
       [peoplePicker dismissViewControllerAnimated:YES completion:nil];}// 当用户选中某一个联系人时会执行该方法,并且选中联系人后会直接退出控制器//- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person{
   ////}// 当用户选中某一个联系人的某一个属性时会执行该方法,并且选中属性后会退出控制器- (void)peoplePickerNavigationController:(ABPeoplePickerNavigationController*)peoplePicker didSelectPerson:(ABRecordRef)person property:(ABPropertyID)property identifier:(ABMultiValueIdentifier)identifier{
       [self peoplePickerNavigationControllerDidCancel:peoplePicker];        ABMultiValueRef phones = ABRecordCopyValue(person, property);    CFIndex phoneCount = ABMultiValueGetCount(phones);    NSString *phoneValue = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(phones, identifier);    //回调block，把号码带回去    if (self.phoneNumberBlock) {
           self.phoneNumberBlock(phoneValue);    }    CFRelease(phones);}

5、处理未开通通讯录权限情况

- (void)setContactAuthorization{
       //主线程刷新UI    dispatch_async(dispatch_get_main_queue(), ^{
           UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"温馨提示" message:@"您没有开启通讯录权限，去开通权限！" preferredStyle:UIAlertControllerStyleAlert];        UIAlertAction *action1 = [UIAlertAction actionWithTitle:@"不了" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
           }];        UIAlertAction *action2 = [UIAlertAction actionWithTitle:@"这就去" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
               if (@available(iOS 10.0, *)) {
                   [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString] options:@{
   } completionHandler:^(BOOL success) {
                   }];            } else {
                   // Fallback on earlier versions                [[UIApplication sharedApplication] openURL:[NSURL URLWithString:UIApplicationOpenSettingsURLString]];            }        }];        [alert addAction:action1];        [alert addAction:action2];        [KeyWidow.rootViewController presentViewController:alert animated:YES completion:nil];    });}

6、外部使用该封装类

//在外部使用该封装类，需要强引用，否则对象会提前释放后，导致block提前释放，以至于无法回调@property (nonatomic, strong) ContactManager *contactManager;

self.contactManager = [[ContactManager alloc] init];

[self.contactManager presentAddressBookViewControllerWithPhoneNumber:^(NSString * _Nonnull phoneNumber) {
           dispatch_async(dispatch_get_main_queue(), ^{
               NSLog(@"%@",phoneNumber);        });    }];

也可以使用单例写法，这时候需要在ContactManager类中实现创建单例方法：

[[ContactManager shareAddressBook] presentAddressBookViewControllerWithPhoneNumber:^(NSString * _Nonnull phoneNumber) {
           dispatch_async(dispatch_get_main_queue(), ^{
               NSLog(@"%@",phoneNumber);        });    }];
