Re: Managing navigation in an iOS app

Hi James, I'd suggest that you're probably pushing the idea of decoupling things a bit too far here. View Controllers are inherantly tied to the behaviour of your application, and your user's experience of the flow through it. In 95% of cases, it's absolutely correct for the view controller t

premultiplying alpha

After much searching about, I discovered (contrary to what the docs say), that NSBitmapImageReps do not always premultiply their r/g/b by their alpha. Because of this, I've dived in, and attempted to write my own premultiplication, but something is going very wrong. Some images are coming out

Re: EXC_BAD_ACCESS

Your initBezierPath method reallocates and reinitialises a path that's already been created. It also autoreleases the result (as the allocation method doesn't start with alloc, copy, mutableCopy, retain or new). The result is that the first time 'path' is assigned it gets a non-released value.

NSCollectionView deselection

Hi, I have, after much struggling with the documentation, managed to create an NSCollectionView that displays all the items I want it to. However, selection isn't quite working right. When the user clicks on item A, setSelected:YES is sent to the NSCollectionViewItem subclass for A. This ple
