ABUnknownPersonViewController crashes

Question

Im using this code to show an ABUnknowPersonViewController for showing a record from a person which was created from a vCard String:

- (ABRecordRef)person {
    if (person == NULL) {
        ABPersonCreator *creator = [[ABPersonCreator alloc] initWithVcardString:vcardString];

        person = creator.person;
        CFRetain(person);

        [creator release];  
    }

    return person;
}

- (UIView *)fullscreenView {
    unknownPersonController = [[ABUnknownPersonViewController alloc] init];

unknownPersonController.displayedPerson = self.person;
    unknownPersonController.allowsAddingToAddressBook = YES;
    unknownPersonController.allowsActions = YES;
    unknownPersonController.unknownPersonViewDelegate = self;
    return unknownPersonController.view;
}

Can someone help me out with this?

thx Philip

Answer 1

The solution to this problem for me was that I wasn't passing the right stuff when building the ABRecordRef. For instance, I tried to simply set a string to a property when it instead wanted a kABMultiStringPropertyType. The exception would only occur after trying to launch the UnknownPersonViewController.

Check your datatypes and make sure that you're building the right thing.

不应让unknownPersonViewController具有自动释放功能，因为它已返回视图？
