以编程方式请求访问联系人

Question

自从更新到iOS 6后，我注意到我在iPhone地址簿中添加联系人的代码不再有效。我认为这是一个与权限相关的问题，因为Apple在访问联系人之前现在需要用户权限（修复this问题）。

我希望该应用能够自动请求访问联系人的权限，如下面的屏幕截图所示，但事实并非如此。尝试添加联系人时失败ABAddressBookErrorDomain error 1。

我是否需要以编程方式启动对联系人请求对话框的访问？怎么做的？

Answer 1

根据Apple网站上的this documentation（向下滚动到页面中间的隐私），在以编程方式访问之前，必须先获得对地址簿的访问。这就是我最终要做的事情。

  #import <AddressBookUI/AddressBookUI.h>

  // Request authorization to Address Book
  ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);

  if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
    ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
      if (granted) {
          // First time access has been granted, add the contact
          [self _addContactToAddressBook];
      } else {
          // User denied access
          // Display an alert telling user the contact could not be added
      }
    });
  }
  else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
    // The user has previously given access, add the contact
    [self _addContactToAddressBook];
  }
  else {
    // The user has previously denied access
    // Send an alert telling user to change privacy setting in settings app
  }

更新适用于iOS 9及更高版本：

在iOS 9中不推荐使用地址簿UI框架。请改用ContactsUI框架中定义的API。要了解详情，请参阅ContactsUI

这对我来说是完美的伎俩！

在iOS6上，Apple引入了新的隐私控制，用户可以通过每个应用程序控制联系人和日历的访问权限。因此，在代码方面，您需要添加一些方法来请求权限。在iOS5或之前，我们总是可以调用

ABAddressBookRef addressBook = ABAddressBookCreate();

获取地址簿没有任何问题，但在iOS6中，如果您没有权限，此调用将只返回空指针。这就是为什么我们需要更改方法来获取ABAddressBookRef。

__block BOOL accessGranted = NO;
if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
    dispatch_semaphore_t sema = dispatch_semaphore_create(0);
    ABAddressBookRequestAccessWithCompletion(addressBook, ^(bool granted, CFErrorRef error) {
        accessGranted = granted;
        dispatch_semaphore_signal(sema);
    });
    dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
    dispatch_release(sema);   
}
else { // we're on iOS 5 or older
    accessGranted = YES;
}

if (accessGranted) {
    // Do whatever you want here.
}

在代码中，信号量用于阻塞直到响应，而ABAddressBookRequestAccessWithCompletion将在应用程序之前没有询问时请求权限。否则，它只会按照设置 - 隐私 - 联系方式中的设置进行操作。

对于联系人框架：

- (void)checkPermissionForCNContacts
{
    switch ([CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts])
    {
        case CNAuthorizationStatusNotDetermined:
        {
            [[[CNContactStore alloc] init] requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
                if (granted == YES)
                    [self showCNContactPicker];
            }];
        }
            break;
        case CNAuthorizationStatusRestricted:
        case CNAuthorizationStatusDenied:
                // Show custom alert
            break;
        case CNAuthorizationStatusAuthorized:
            [self showCNContactPicker];
            break;

Xcode5中的iOS6.1上的yunas代码存在一些问题。有些small adaptions它对我有用。

问题是iOS 6中的ARC不允许dispatch_release(sema);这是工作代码。注意：我使用m_addressbook代替addressbook作为ABAddressBookRef！

ViewController.m

#import "ViewController.h"
#import <AddressBook/AddressBook.h>
#import <AddressBook/ABAddressBook.h>
#import <AddressBook/ABPerson.h>

@interface ViewController ()

@property (nonatomic, strong) NSMutableArray* contactList;

@end

@implementation ViewController

- (void)viewDidLoad
{
  [super viewDidLoad];

  ABAddressBookRef m_addressbook =  ABAddressBookCreateWithOptions(NULL, NULL);

  __block BOOL accessGranted = NO;
  if (ABAddressBookRequestAccessWithCompletion != NULL) { // we're on iOS 6
      dispatch_semaphore_t sema = dispatch_semaphore_create(0);
      dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
          @autoreleasepool {
              // Write your code here...
              // Fetch data from SQLite DB
          }
      });

      ABAddressBookRequestAccessWithCompletion(m_addressbook, ^(bool granted, CFErrorRef error) {

          dispatch_semaphore_signal(sema);
      });
      dispatch_semaphore_wait(sema, DISPATCH_TIME_FOREVER);
  }
  else { // we're on iOS 5 or older
      accessGranted = YES;

如果有任何人在iOS5中遇到地址簿问题，请使用

ABAddressBookRef addressBook = ABAddressBookCreate(); 

而不是

ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL,NULL);

Answer 8

ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
        dispatch_async(dispatch_get_main_queue(), ^{
            if (!granted){
                    [[[UIAlertView alloc] initWithTitle:@"Contacts Access Denied"
                                                message:@"This app requires access to your device's Contacts.\n\nPlease enable Contacts access for this app in Settings / Privacy / Contacts"
                                               delegate:nil
                                      cancelButtonTitle:@"Dismiss"
                                      otherButtonTitles:nil] show];

                //access authorized
            }
        });

Answer 13

根据iOS最新的Apple开发文档，Apple坚持使用Contact之外的AddressBook。

CNAuthorizationStatus authorizationStatus = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
    switch (authorizationStatus) {
        case CNAuthorizationStatusNotDetermined: {

            break;
        }
        case CNAuthorizationStatusRestricted: {

            break;
        }
        case CNAuthorizationStatusDenied:{

            return;
        }
            break;
        case CNAuthorizationStatusAuthorized: {

            break;
        }
    }

以上目标C代码有助于查找是否授予天气联系人访问权限。
