ios - 如何在 CoreData 中存储 ABRecordRef 对象

Question

我想存储 ABRecordRef对象，即格式为 <CPRecord: 0xa2a3500 ABPerson>使用 Coredata。

虽然我尝试像这样存储

NSEntityDescription *entityDescriptionStrings = [NSEntityDescription entityForName:@"ContactsStrings" inManagedObjectContext:context];

ContactsStrings *contactsManagedObjectStrings = [[ContactsStrings alloc] initWithEntity:entityDescriptionStrings insertIntoManagedObjectContext:context];

        ABRecordRef recordRef = CFArrayGetValueAtIndex(contactInfoArray, i);
[contactsManagedObjectStrings setValue:(__bridge id)(recordRef) forKey:@"record"];

我收到崩溃消息

我取为 Integer32 数据类型的记录。

由于未捕获的异常而终止应用程序 NSInvalidArgumentException ,

reason: 'Unacceptable type of value for attribute: property = "record"; desired type = NSNumber; given type = __NSCFType; value = .

Answer 1

试试这个，

ABRecordRef recordRef = CFArrayGetValueAtIndex(contactInfoArray, i);
ABRecordId recId = ABRecordGetRecordID(recordRef);
NSNumber *recordId = [NSNumber numberWithInt:(int)recId];
[contactsManagedObjectStrings setValue:recordId forKey:@"record"];

恢复

//recordId is the value of record key from managedobject
ABRecordId recId = (ABRecordId)[recordId intValue];
ABRecordRef recordRef = ABAddressBookGetPersonWithRecordID(ddressBook, recId);
