I'm making an accelerometer based app using cocos2d, and I noticed that it's possible to set the accelerometer update time. [[UIAccelerometer sharedAccelerometer] setUpdateInterval: (1.0f / 60.0f)]; I was wondering if updating the accelerometer very often like this, 60 times a second is a battery drain? Or should I not worry at all? ...

I have a UITableView with the editingAccessoryType set to UITableViewCellAccessoryDisclosureIndicator. The result is this: It works, but I have a custom background, and therefore a custom separator color.

An object which used to identify itself as NSCFArray under previous iPhoneOSes now seems to identify itself as __NSArrayI under devices running iOS 4.0. Any idea what's up with this? I can't find it in any documentation. In addition, it doesn't match "[NSArray class]". It should be a simple array. It's defined like this: NSDictionary...

So I made 4 different images (actually PDFs) with 4 different sizes of the map (the largest has something like 5700 x 6700px) I add the smallest (the overview) to the CATiled...
I keep my database open for the life of the app and close it on termination. Now with iOS 4.0 multitasking, when going to the background, my app saves data but doesn't close the database. I believe this means that my app will always eventually get purged from memory without ever properly closing the database (or finalizing statements)....
