ios 中的联系人缺少一些必需的关键描述符
Contact is missing some of the required key descriptors in ios
我已经使用以下方法检索了所有联系人
- (void)getAllContacts:(void(^)(NSArray *array))handler
{
CNAuthorizationStatus status = [CNContactStore authorizationStatusForEntityType:CNEntityTypeContacts];
if (status == CNAuthorizationStatusDenied || status == CNAuthorizationStatusDenied)
{
UIAlertController *alert = [UIAlertController alertControllerWithTitle:nil message:@"This app previously was refused permissions to contacts; Please go to settings and grant permission to this app so it can use contacts" preferredStyle:UIAlertControllerStyleAlert];
[alert addAction:[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]];
[self presentViewController:alert animated:TRUE completion:nil];
return;
}
CNContactStore *store = [[CNContactStore alloc] init];
[store requestAccessForEntityType:CNEntityTypeContacts completionHandler:^(BOOL granted, NSError * _Nullable error) {
// make sure the user granted us access
if (!granted)
{
dispatch_async(dispatch_get_main_queue(), ^{
// user didn't grant access;
// so, again, tell user here why app needs permissions in order to do it's job;
// this is dispatched to the main queue because this request could be running on background thread
});
return;
}
// build array of contacts
NSMutableArray *contacts = [NSMutableArray array];
NSError *fetchError;
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]]];
BOOL success = [store enumerateContactsWithFetchRequest:request error:&fetchError usingBlock:^(CNContact *contact, BOOL *stop) {
[contacts addObject:contact];
}];
if (!success)
{
NSLog(@"error = %@", fetchError);
return;
}
handler((NSArray *)contacts);
}];
}
联系人列在表格视图中。现在我正在尝试 select 来自 ``,
的特定联系人
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
{
CNContact *contact = [arrContacts objectAtIndex:indexPath.row];
NSArray *keys = @[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]];
CNContactViewController *contactController = [CNContactViewController viewControllerForContact:contact];
contactController.delegate = self;
contactController.allowsEditing = YES;
contactController.allowsActions = YES;
contactController.displayedPropertyKeys = keys;
[self.navigationController pushViewController:contactController animated:TRUE];
}
但是它说
Contact 0x7fc732654530 is missing some of the required key descriptors
有知道的请帮我解决一下。谢谢
您需要添加 [CNContactViewController descriptorForRequiredKeys]
作为 keysToFetch
的数组,您必须传入 CNContactFetchRequest
。
示例:
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName], [CNContactViewController descriptorForRequiredKeys]]];
在 keysToFetch 数组的末尾添加 "CNContactViewController.descriptorForRequiredKeys"。
在我这样做之后为我工作。
示例:
NSArray *keysToFetch = @[CNContactIdentifierKey, CNContactGivenNameKey, CNContactFamilyNameKey, CNContactPhoneNumbersKey, CNContactImageDataAvailableKey, CNContactImageDataKey, CNContactViewController.descriptorForRequiredKeys];
换你的线
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName]]];
和
CNContactFetchRequest *request = [[CNContactFetchRequest alloc] initWithKeysToFetch:@[CNContactIdentifierKey, CNContactEmailAddressesKey, CNContactBirthdayKey, CNContactImageDataKey, CNContactPhoneNumbersKey, [CNContactFormatter descriptorForRequiredKeysForStyle:CNContactFormatterStyleFullName],[CNContactViewController descriptorForRequiredKeys]]];
有些人在 swift 中使用它然后添加
let request:CNContactFetchRequest
request = CNContactFetchRequest(keysToFetch: [CNContactGivenNameKey, CNContactFamilyNameKey, CNContactMiddleNameKey, CNContactEmailAddressesKey,CNContactPhoneNumbersKey,CNContactViewController.descriptorForRequiredKeys()])
我不确定这是 Apple 错误处理的错误还是我缺乏理解,但我的解决方案与密钥描述符完全无关。
如果要在 CNContactViewController
中显示 CNContact
从 CNContactPickerViewController
中选择的 CNContactViewController
没有 联系权限,您必须确保 CNContactViewController
嵌入在 UINavigationController
.
中
在我的例子中,我还必须向控制器添加左和右 UIBarButtonItem
来处理解雇。请注意,如果您将 CNContactViewController
推到 UINavigationController
上,这可能不是必需的,但是因为我使用的是 present
方法,所以这是必要的。
希望这能帮助其他人解决这个神秘的错误!
