I'm having some problems with the accelerometer. When I first started develop my game the controls felt very snappy and precise, but when adding more graphical elements the accelerometer feels like it's reacting very late and sometimes not as precise as before. I'm having a framerate of around 40fps. This is where I read the values (as ...
Prior to xcode 3.2.1, you could cycle through the list of files your in history through a keyboard shortcut (Cmd + Option + L/R Arrow key).

Hello, I set some values to NSUserDefaults and if I retrieve them without exiting the app, everything works fine. When I restart the app, the changes disappear in 95% of the time. In 5% of the time everything is being saved ok. I'm facing this problem for the first time. In my other apps I don't usually save NSString in NSUserDefaults....
I've been having some trouble with Snow Leopard's new block-based API for observing notifications from NSWorkspace's NSNotificationCenter. If I register for notifications using the traditional selector-based method, then I am able to observe the desired notification.
