The iPhone has a private list of effects that Apple uses, such as "genieEffect" and "slurpEffect". I'm wondering how one would go about implementing the slurp effect (this is when you trash a mail message or a note). I understand how to use Core Animation, but I'm not sure exactly what parts of it they're using to get that animation. ...
Here is the interface of my object: @interface MyItem : NSObject { sqlite3 *database; NSInteger *primaryKey; NSInteger *accountKey; NSInteger *categoryKey; NSString *title; BOOL hydrated; BOOL dirty; NSData *data; // Why do I need this? } The primary key will be auto generated in Sqlite and I am storing the integers, foreign k...

So an iPhone can pair with a bluetooth headset and use it to make calls (although an iPod touch with the 3.0 OS can not pair with a headset, go figure). But can I write an app that can access paired blue-tooth devices and their functionality (like the mic input from a headset). This would be useful in VOIP apps or even multi-player ga...
