我正在使用 native CNContactViewController 添加联系人,一旦保存联系人,它就会返回带有“:ABPerson”后缀的联系人标识符,当我交叉检查联系人列表时,相同的联系人会出现不同的标识符。
有谁知道如何获取实际的联系人标识符?
要创建的代码:
- (IBAction)didSelectedAddContact:(id)sender {
CNMutableContact *contact = [CNMutableContact new];
CNContactViewController *contactController = [CNContactViewController viewControllerForNewContact:contact];
NSLog(@"contact id : %@", contact.identifier);
contactController.allowsEditing = true;
contactController.allowsActions = true;
contactController.delegate = self;
[self.navigationController pushViewController:contactController animated:YES];
}
委托(delegate)回调:
- (void)contactViewController:(CNContactViewController *)viewController didCompleteWithContact:(nullable CNContact *)contact{
_contact = contact;
[viewController.navigationController popViewControllerAnimated:YES];
}
下面的函数返回 nil:
- (CNContact*) getContactFromStoreForIdentifier:(NSString*) identifier
{
CNContact *updatedContact = nil;
id descriptor = [CNContactViewController descriptorForRequiredKeys];
CNContactStore *store = [CNContactStore new];
NSError *error;
updatedContact = [store unifiedContactWithIdentifier:identifier
keysToFetch:@[descriptor]
error:&error];
// Found?
if (updatedContact == nil)
{
if (error != nil)
{
}
}
return updatedContact; }
@Parameter:从 didCompleteWithContact 接收到的 CNContact 对象的标识符:委托(delegate)回调。
最佳答案
您必须为 viewController 设置一个 contactStore。
CNContactStore *store = [CNContactStore new];
contactController.contactStore = store;
If not this property is not set, than adding the contact to the user's contacts is disabled.
