I need to imlement in cocoa, a design that relies on multiple threads. I started at the CoreFoundation level - I created a CFMessagePort and attached it to the CFRunLoop, but it was very inconvenient as (unlike on other platforms) it needs to have a (systemwide) unique name, and CFMessagePortSendRequest does not process callbacks back t...

I want to use the property currentPlaybackTime, which returns a double value to trigger a series of if statements at certain points throughout the movie's playback to pause it. Because of the approximate behavior of doubles, it never syncs up with the value in my if statement, and the movie doesn't stop. I can't use a range though becaus...

I'd LOVE to know what I'm doing wrong here. I'm a bit of a newbie with CGImageRefs so any advice would help. I'm trying to create a bitmap image that has as it's pixel values a weighted sum of the pixels from another bitmap, and both bitmaps are 16bits per channel. For some reason I had no trouble getting this to work with 8bit images b...

Hello! In most of my classes that work with defaults I make the defaults object settable: @property(retain) NSUserDefaults *defaults; This is supposed to make testing easier: // In a nearby test class: - (void) setUp { [super setUp]; NSUserDefaults *isolatedDefaults = [[NSUserDefaults alloc] init]; [someObjectBeingTested ...
