NSViewController awakeFromNib and NSTableView numberOfRowsInTableView

Hello, I have come across what seems to be a weird situation and can't really think of a good solution. I'm relatively new to Cocoa so its probably just a simple misunderstanding. I have a subclass of NSViewController that also acts as the delegate for the NSTableView that it controls. T

Substituting characters in a UITextField

I'd like to make some character substitutions in a UITextField while the user is typing. For example, when the user types "C", I'd like an arrow (\u2192) to appear in the textfield instead. I've been playing with the textField:shouldChangeCharactersInRange delegate method. But I don't see

I've gone back to my code and tried to reproduce the error. Now I can't. So I was doing something else stupid that I've since changed. Now if I do the usual [[NSDate alloc] init] it seems to be behaving as expected. [NSDate date] can generate the error, but that doesn't surprise me. John

Re: GC pros and cons

consistently using the technique pushes the null check to one or two placessuch as when the pointer is alloc'ed. regardless of whether messaging nil is a problem or not, if nil isn't a a valid state for a variable, I check it and throw an exception as a matter of defensive programming
