Hello, all
I'm just curious about the naming convention for Core Graphics and
Foundation.
For example, NSMakeRect and CGRectMake are similar but different about
where the Rect is in its method name.
What is even worse is NSPointInRect and CGRectContainsPoint.
So, if a person is used to the
I noticed the differences too, and my guess was that it makes it
easier to find functions related to CGRects, by searching the API for
terms that contain CGRect. I actually prefer it this way.

Yeah.. I agree with you in the point of view. But if we take a look at
it from different angle, NSMakeRect is better, because it is more
understandable due to its resemblance to spoken English.
NSPointInRect vs. CGRectContainsPoint is more subtle. Is it Rect-
related method or Point-related
Rather than doing it every 1000 iterations, make it be time-based.
Yes, I agree with you there. That's what I myself usually do in fact.
I'm not sure what you're referring to when you talk about other
techniques, but in general it is forbidden to access the GUI of a

Hello nice people,
I wrote a little OS X application that uses a NSTimer. I initialize it
like this:
repeatingTimer = [NSTimer scheduledTimerWithTimeInterval:4.0
target:self
selector:@selector(timerFireMethod)

Missing colon after timerFireMethod (within the @selector statement). It
catches me out too. Not sure why it works for you in debug builds. I have
not observed that behaviour.

Let's say I want to have the field editor for a table view appear 2 pixel below

Unfortunatly, as expected, my window is clipping how ever i just

Hi Clark,
If your keys are integers, then you've got the best hash function
possible: the identity function :)
I know what you mean, but that's not strictly speaking true. If your

very good hash function.
