Error in accessing address book in iOS<6

Question

I have implemented method to get contacts.

For iOS 6, I used below code to get permission from the user:

CFErrorRef myError = NULL;
ABAddressBookRef myAddressBook = ABAddressBookCreateWithOptions(NULL, &myError);
ABAddressBookRequestAccessWithCompletion(myAddressBook,^(bool granted, CFErrorRef error)
{
   if(granted)
    {
        [self GetContactInformation];
    }
   else
    {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Contacts" message:@"You didn't permit us to access your contact details." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
    }
});
CFRelease(myAddressBook);

Above code working fine in iOS 6 but below iOS 6 I am getting below error:

You can use MACROS to filter this:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 60000
CFErrorRef myError = NULL;
ABAddressBookRef myAddressBook = ABAddressBookCreateWithOptions(NULL, &myError);
ABAddressBookRequestAccessWithCompletion(myAddressBook,^(bool granted, CFErrorRef error)
{
   if(granted)
    {
        [self GetContactInformation];
    }
   else
    {
        UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Contacts" message:@"You didn't permit us to access your contact details." delegate:nil cancelButtonTitle:@"OK" otherButtonTitles: nil];
        [alert show];
        [alert release];
    }
});
CFRelease(myAddressBook); 
#else
    [self GetContactInformation];
#endif

Let us know if it works.

Well, it seems you know the answer already. Both of those functions are iOS 6+ only, and do not exist in prior SDKs, meaning their symbols are undefined. You have to code to the lowest common denominator, or up your target to iOS 6.

But for iOS6 and above I need to write that code to access contacts. I think dilip solved my problem. – swati sharma Nov 23 '12 at 12:13
