Hi everyone. I'm new to iPhone development and have a question I hope someone can help me with.

I have a programmer working on an iPhone app for me and when I run the app in the simulator, it works great. But when I try to run it on my actual iPhone, I get a EXC_BAD_ACCESS error and the app locks up.

Looking at the debugger, it's referencing the following code in my MainController as the problem:

 -(void)loadAddressBook{
     NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
     addressBookLoaded=1;
    [AddressbookRecord readAllContactTable:[self getDBPath]];
     ABAddressBookRef addressBook = ABAddressBookCreate();
     for(NSUInteger i=1;i<=ABAddressBookGetPersonCount(addressBook);i++) {
         ABRecordRef myPerson =ABAddressBookGetPersonWithRecordID (addressBook,(ABRecordID)(i));
         NSString *name = (NSString*)ABRecordCopyCompositeName(myPerson);
         //save in database
         AddressbookRecord *addObj = [[AddressbookRecord alloc] initWithPrimaryKey:0];
         addObj.ClientName=name;
         [addObj addNewContactEntry];
     }
     addressBookLoaded=2;
     [pool release];
 }

More specifically, it points to this specific line as the problem:

NSString *name =(NSString*)ABRecordCopyCompositeName(myPerson);

My programmer can't seem to figure out what the problem is since he can't replicate it on his end. Does anyone have any ideas what would cause this problem???

Thanks!
