Question

I have a memory management problem that i can’t seem to find a solution for. The code is as follow:

-(ABRecordRef)convertABCPerson:(ABCPerson*) person{

// create new address book person record
ABRecordRef aRecord = ABPersonCreate(); 

[self setValuesFor:person toARecord:aRecord];

return aRecord;

}

So i convert my own class to a ABRecordRef and now I need somehow to “autorelease” this object(So i can take ownership in a different object). I am using ARC and a ABRecordRef cannot be toll-bridged to a Cocoa foundation class. Any ideas how i could solve this memory management issue ?

Thanks for the help 🙂

I found a solution to my problem. The only thing i had to do is cast it to id and using bridge transfer to let ARC handle the memory management. From an other class you can do a ABRecordRef cast as __bridge so that ARC handles the record correctly.

The solution:

-(id)convertABCPerson:(ABCPerson*) person{

    // create new address book person record
    ABRecordRef aRecord = ABPersonCreate(); 

    [self setValuesFor:person toARecord:aRecord];

    id record = (__bridge_transfer id)aRecord;

    return record;
}

The casting back:

personViewController.displayedPerson = (__bridge ABRecordRef)[[ABCFacade sharedABCFacade] convertABCPerson:goldenRecord];
