Thank you for your reply and pointers.

Hi all,
I have an editor with a list of files, where I switch the contents of a
NSTextView in and out when selecting a new file.
For the switching I use the following lines:
NSLog(@"[1] %s, layoutManager count: %d", __PRETTY_FUNCTION__,
[[[textView textStorage] layoutManagers] count]);

Hi Shawn,
Thankyou for the detailed explanation.
I've probably been too quick to jump to the conclusion, and even
though it works better (I've still seen no chops), I agree that
something else most likely have an impact on my application.

Performance measurement may seem simple at first glance but it can
be very subtly hard to get right. That's why tools for it are
supplied with Xcode, and why they need explicit support from the
operating system.

Hi all,
I just want to let you know that I discovered I did a terrible mistake
today.
In other words: you don't have to learn from your own mistakes, if you
can learn from mine. =)
I investigated this, because my rendering was choppy.
The code...
- (void)renderObject
{
}
- (void)renderAl
You're right, it's not needed, and furthermore, I just checked, the
warnings won't disappear.
Everyone, disregard what I wrote about self->
I believe that prefixing the parameters is most likely the best way
(and as a good example for us, the guys at Apple does it as well).
Love,

Hi Nik,
self is a pointer, so you might want to change "self." into "self->"
I usually prefix arguments with an 'a' (a for Argument):
- (id)initWithLabel:(NSString *)aLabel pin:(NSString *)aPin seed:
(NSString *)aSeed
{
self = [super init];
if(self)
{

Hi Devon,
Perhaps you're looking in the wrong direction.
Try checking if the image type on Leopard is the same as the image
type on Tiger.
If the image type on Tiger is 8 bit (or monochrome), and the image
type on Leopard is 24-bit color, it might be the image itself, which
forces your out
First, you should install XCode (either from your System Installation
DVD or by downloading it from connect.apple.com - you'd need to
register as a developer then).
When installed, you should get familiar with XCode, copy one of the
example-projects to your desktop from /Developer/Examples

Go for OpenGL. If you choose something else, you might run into
problems along the road.
I know OpenGL can handle both 2D and 3D, and you get a fairly good
support from samples on the Web.
