应用程序未请求联系人权限以访问 iOS 9 中的联系人

Question

我正在使用以下代码获取 iPhone 联系人，但我的应用程序在 iOS 9 中未获得允许联系人的权限。我从堆栈中找到了这段代码，其他引用也相同。

   - (void)getPersonOutOfAddressBook
{
    //1
    CFErrorRef error = NULL;
    ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, &error);

    if (addressBook != nil) {
        NSLog(@"Succesful.");

        //2
        NSArray *allContacts = (__bridge_transfer NSArray *)ABAddressBookCopyArrayOfAllPeople(addressBook);

        //3
        NSUInteger i = 0; for (i = 0; i < [allContacts count]; i++)
        {
            NSMutableDictionary *persiondict  =[[NSMutableDictionary alloc]init] ;
//            Person *person = [[Person alloc] init];
            ABRecordRef contactPerson = (__bridge ABRecordRef)allContacts[i];

            //4
            NSString *firstName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson,
                                                                                  kABPersonFirstNameProperty);
            NSString *lastName = (__bridge_transfer NSString *)ABRecordCopyValue(contactPerson, kABPersonLastNameProperty);
            NSString *fullName = [NSString stringWithFormat:@"%@ %@", firstName, lastName];

//            person.firstName = firstName;
//            person.lastName = lastName;
//            person.fullName = fullName;
            [persiondict setValue:fullName  forKey:@"fullName"] ;

            //email
            //5
            ABMultiValueRef emails = ABRecordCopyValue(contactPerson, kABPersonEmailProperty);

            //6
            NSUInteger j = 0;
            for (j = 0; j < ABMultiValueGetCount(emails); j++) {
                NSString *email = (__bridge_transfer NSString *)ABMultiValueCopyValueAtIndex(emails, j);
                if (j == 0) {
//                    person.homeEmail = email;
                    [persiondict setValue:email  forKey:@"email"] ;

//                    NSLog(@"person.homeEmail = %@ ", person.homeEmail);
                }
                else if (j==1)
                [persiondict setValue:email  forKey:@"email"] ;

            }

            //7 
            [ArrUserOfContacts addObject:persiondict];
        }

        //8
        CFRelease(addressBook);
    } else { 
        //9
        NSLog(@"Error reading Address Book");
    } 
}

我在这里找不到问题，用户如何获得访问联系人的权限。任何建议都会有所帮助。

Answer 1

您需要使用 ABAddressBookRequestAccessWithCompletion()

请求权限

ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
  if (!granted){
    NSLog(@"Just denied");
    return; 
  }
  NSLog(@"Just authorized");
});

Answer 2

ABAddressBookRequestAccessWithCompletion 在 iOS 中已弃用 9. 现在您应该使用联系人框架。这是 Objective C:

中的示例

CNContactStore * contactStore = [CNContactStore new];
[contactStore requestAccessForEntityType:entityType completionHandler:^(BOOL granted, NSError * _Nullable error) {
             if(granted){
                 //
             }
         }];

在Swift 3:

CNContactStore().requestAccess(for: .contacts, completionHandler: { granted, error in
        if (granted){
             //
        }
    })

如果用户没有拒绝或批准对您应用中的联系人的权限，这只会请求权限。您不能请求已被用户拒绝的权限（至少现在在 iOS 10），您可以做的是将用户重定向到设置。

Answer 3

如果您想检查用户是否授予联系人权限，如果未授予权限，则显示警报以在设置中移动用户以授予权限。

然后使用下面的函数checkContactsPermission作为：

-(void)checkContactsPermission {

    //Check permission status
    switch (ABAddressBookGetAuthorizationStatus()) {
        case kABAuthorizationStatusAuthorized:

            // Already permission given

            break;
        case kABAuthorizationStatusDenied:{

            // Permission not given so move user in settings page to app.

            UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Alert!" message:@"his app requires access to your contacts." preferredStyle:UIAlertControllerStyleAlert];

            UIAlertAction* SettingsButton = [UIAlertAction actionWithTitle:@"Settings"
                                                                     style:UIAlertActionStyleDefault
                                                                   handler:^(UIAlertAction * action)
                                             {
                                                 NSURL * settingsURL = [[NSURL alloc] initWithString:[NSString stringWithFormat:@"%@%@",UIApplicationOpenSettingsURLString,[[NSBundle mainBundle]bundleIdentifier]]];

                                                 if (settingsURL) {
                                                     [[UIApplication sharedApplication] openURL:settingsURL];
                                                 }
                                             }];

            UIAlertAction* DeniedButton = [UIAlertAction actionWithTitle:@"Denied"
                                                                   style:UIAlertActionStyleDefault
                                                                 handler:^(UIAlertAction * action)
                                           {

                                           }];

            [alert addAction:SettingsButton];
            [alert addAction:DeniedButton];

            [self presentViewController:alert animated:YES completion:nil];
        }

        case kABAuthorizationStatusRestricted: {

            // Permission not given so move user in settings page to app.

            UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Alert!" message:@"his app requires access to your contacts." preferredStyle:UIAlertControllerStyleAlert];

            UIAlertAction* SettingsButton = [UIAlertAction actionWithTitle:@"Settings"
                                                                style:UIAlertActionStyleDefault
                                                              handler:^(UIAlertAction * action)
                                        {
                                            NSURL * settingsURL = [[NSURL alloc] initWithString:[NSString stringWithFormat:@"%@%@",UIApplicationOpenSettingsURLString,[[NSBundle mainBundle]bundleIdentifier]]];

                                            if (settingsURL) {
                                                [[UIApplication sharedApplication] openURL:settingsURL];
                                            }
                                        }];

            UIAlertAction* DeniedButton = [UIAlertAction actionWithTitle:@"Denied"
                                                               style:UIAlertActionStyleDefault
                                                             handler:^(UIAlertAction * action)
                                       {

                                       }];

            [alert addAction:SettingsButton];
            [alert addAction:DeniedButton];

            [self presentViewController:alert animated:YES completion:nil];
        }
            break;

        case kABAuthorizationStatusNotDetermined:

             // Permission not determin. so request for permission.
            ABAddressBookRequestAccessWithCompletion(ABAddressBookCreateWithOptions(NULL, nil), ^(bool granted, CFErrorRef error) {
                if (granted){

                    // Already permission given
                }
            });

            break;
    }
}

对于iOS10你可以使用联系人框架来检查权限。
