我正在尝试开发一个应用程序，用户可以在其中通过 iMessage 发送消息。所以我可以从 AddressBook 导入联系人列表，并通过 MessageUI Framework 发送消息，但我想知道哪些导入的联系人也有 iPhone 所以他们可以使用 iMessage 功能。有什么方法可以从 kABPerson...Property 中找出来吗？
这是我的代码:
ABAddressBookRef addressBookRef = ABAddressBookCreateWithOptions(NULL, NULL);
if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusNotDetermined) {
ABAddressBookRequestAccessWithCompletion(addressBookRef, ^(bool granted, CFErrorRef error) {
ABAddressBookRef addressBook = ABAddressBookCreate( );
});
}
else if (ABAddressBookGetAuthorizationStatus() == kABAuthorizationStatusAuthorized) {
CFErrorRef *error = NULL;
ABAddressBookRef addressBook = ABAddressBookCreateWithOptions(NULL, error);
CFArrayRef allPeople = ABAddressBookCopyArrayOfAllPeople(addressBook);
CFIndex numberOfPeople = ABAddressBookGetPersonCount(addressBook);
for(int i = 0; i < numberOfPeople; i++) {
ABRecordRef person = CFArrayGetValueAtIndex( allPeople, i );
NSString *firstName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonFirstNameProperty));
NSString *lastName = (__bridge NSString *)(ABRecordCopyValue(person, kABPersonLastNameProperty));
//Something like this ?
BOOL *doeshaveiPhone = (__bridge BOOL *)(ABRecordCopyValue(person, kABPersonPhoneIPhoneLabel));
NSLog(@"Name:%@ Surname: %@", firstName, lastName);
ABMultiValueRef phones = ABRecordCopyValue(person, kABPersonPhoneProperty);
for(CFIndex j = 0; j < ABMultiValueGetCount(phones); j++)
{
CFStringRef phoneNumberRef = ABMultiValueCopyValueAtIndex(phones, j);
CFStringRef locLabel = ABMultiValueCopyLabelAtIndex(phones, j);
NSString *phoneLabel =(__bridge NSString*) ABAddressBookCopyLocalizedLabel(locLabel);
NSString *phoneNumber = (__bridge NSString *)phoneNumberRef;
CFRelease(phoneNumberRef);
CFRelease(locLabel);
NSLog(@" - %@ (%@)", phoneNumber, phoneLabel);
}
}
最佳答案
您的代码是确定地址簿中的人是否拥有 iMessage 的最佳方式。但是，有一个缺点:只有在用户正确设置他们的联系人时它才有效。字段设置不当通常会使开发应用程序变得困难。
这个问题之前有人问过。 Here,得票最高的答案是，
your heurisitic might be ok but it relies on the USER correctly setting that attribute.
depending on the context it might be good enough / or not .. dont know.
there is no real way to detect which user really uses ios (no API)
