Hello, I'm trying to understand how Cocoa does its thing.

For retained properties, I have grown accustomed to a specific way of using the accessor methods to alloc/initialize the actual iVars: - (void)anInitOrAccessorMethod { self.property = [[AClass alloc] init]; [self.property release]; } Anytime I need to set a non-autoreleas...

Cocoa has a plethora of integer masks and codes. For instance, NSCommandKeyMask or NSF1FunctionKey, which are clearly defined and documented in the headers. However, some can be archaic and when accessing accessibility attributes, for instance to get the glyph (AXMenuItemCmdGlyph), you're given an integer number like 111, which represen...
I'm writing an app where support for "promotions" is required, and these promotions could be arbitrarily complex and many different pieces of data might be relevant in their calculation. Therefore, whilst in the early stages of development, I don't want to invent a whole specification schema for these things, I'd rather just write each ...
It's a question about good programming techniques with Cocoa. When you want to call a method on one property of your class, should you use KVC to get the receiver or just put the name of your property? Example, KVC: [[self property] myMethod]; Example, simple: [property myMethod]; Thanks! ...

Hello, I have an array of filenames that i would like to pass to an external application for opening.

I got a view controller class (MyViewController) that deals with a UIView subclass (MyView). I don't want to let any class except the view controller class know about the UIView subclass, so I cannot import MyView.h in MyViewController.h.

I have a cocoa application which has certain subroutines / methods.
