I have a Cocoa view that reacts to -mouseDown and -mouseDragged events

It has about 50 objects that are either NSBezierCurve or NSTextField.
The problem is, after a few seconds of mouse dragging, the view

Two suggestions.
One, you can verify that you are not leaking using one of the tools
provided, Instruments or MallocDebug.
Two, I think you need to provide code examples for list members to

Richard, here is the code I am using, here x, y, i are variables that
define the label position and text.
If I comment this snippet, my view is working well. So I am sure that
there is something in these lines that needs to be done properly,
which I don't know ;-)

I have run Instruments and I see a ton of these calls:

So I indeed see that there's something I am not doing right with the
NSTextField.

I've seen this happen when
I think I know what's the problem, it's this line.
[self addSubview:PatternRateLabel];
With each -drawRect call, NSTextField objects are not being redrawn
from scratch, they are added on top of the existing ones. So I end up
with thousands of them.
I guess I need to put this code in -awake

I guess I need to put this code in -awakeFromNib. And then, if
needed, change the text field strings or properties in -drawRect.
Yes, that did the trick! I now set up these labels in -awakeFromNib
and the view is working well now. Glad I was able to figure it out.

No I do not use anything special there.

You guys are right, all is actually well, it might have been that
Helvetica isn't the prettiest font to use in this color scheme. I
changed it to Lucida Grande and it's looking properly sleek now :-)

if those are the only views you can use
[ self subviews ]
to get an array of them in the order they are currently stacked.

Just create a NSMutableArray before the loop:
NSMutableArray *array = [NSMutableArray arrayWithCapacity:16];
And then add each field to the array right in the loop
for (…) {
…
[array addObject:textField];
}
Great, thanks a lot! Can I then access each element via array[0],
array[1] etc.

My apologies, the full code is this:
