Title
Body
I have an iPad-appliction that syncs contact with the contacts on server side. How do I detect only that ABAdressbook-Entries that have changed? It is possible, that there occur changes on server-side, in my application, or externally on the ipad. When I use void ABAddressBookRegisterExternalChangeCallback ( ABAddressBookRef addressBook, ABExternalChangeCallback callback, void *context ); I get the callback of external changes, but without any information about what changed. How do I get that information? When I use the NSString * const kABModificationDateProperty I don't know what to compare with.
