How To Fully Test Cleanup Code Paths (iOS)?

Hi All, My apologies if this is more appropriate for another group. Please point me in the right direction. I'm interested in testing cleanup and shutdown code (this is a little different than 'save state in -didEnterBackground'). For example, MyViewController -viewDidUnload and -dealloc. From th

-[NSManagedObjectContext save:] takes 30 minutes, then crashes out of memory

I have an app which writes a log to a Core Data SQLite store. I just got a Logs.sql file from a user. It is 270 KB, containing 1251 log entries. Upon launch, the app finds that 284 entries are expired and deletes them. Nothing out of the ordinary so far. App then executes -[NSManagedObjectC

Newbie, here... hope I'm posting to the correct list. In Interface Builder of Xcode 4, I set a key equivalent for my menu items. Sometimes they work, but sometimes they don't. What am I doing wrong? For Example, setting a key equivalent of command-6 for my View->Full Screen menu item works. But,

Hi, What is stored in the "cover" object? If it's the name of a file that is bundled with the app, you can use cell.coverAuthor.image = [UIImage imageNamed:[[data objectAtIndex:index] objectForKey:@"cover"]]; If it's the name of a file stored on "disk" some place (e.g., the Application Suppor

UIView has some convenience methods you can use to convert a CGRect to and from different views’ coordinate systems. Look at the documentation for -convertRect:fromView:

OpenSSL is available for Windows, but I can't see how to feed it an encryption key, just a passphrase which is (apparently) converted to a key. However, since CommonCrypto's CCCrypt uses the key directly, that's what I've got. I'll check Cygwin out. Thanks. (Anyone know how to feed OpenSSL a key

Hi, I'm a little shaky in this area, so I beg your pardon. CALayer has a "contents" property which is a CGImageRef, i.e. a Core Graphic image. CGImages are stored in RAM. CALayer is built on top of OpenGL and uses VRAM to store its bitmap image internally (a texture). Now suppose that I have a
