Not quite answering your original question, but this may provide some
insight. The "imageRep" object you create is autoreleased, and so is
the NSData object. Because you did not "alloc" (or copy) them, they
are temporary, autoreleased objects. So your calling release on it is
not really what you want to do, because it should take care of the
releasing for you when you get back to the event loop.
Could this be something you are running within a loop, so that the
autorelease pool doesn't get a chance to clear itself?
It would be a good idea to either surround your code in a new
autorelease pool, or change your statement to instead explicitly
alloc/init the NSData and the NSBitmapImageRep objects, and then
release them when you are done with them. I can't guarantee that this
will solve the problem, though....

Hello everybody,
I have two lines that load an imageRep of an image on the HD, and
they're leaking memory like hell. Any ideas why this is happening? It
shouldn't, that's the problem.
Code:
imageRep = [NSBitmapImageRep imageRepWithData:[NSData
dataWithContentsOfFile:@"/Library/Desktop Pictures/Aqua Blue.jpg"]];
[imageRep release];
Say I want to load the Aqua Blue desktop pic. *Every* time this gets
called my test app's virtual memory usage increases with 3 MB or more,
I don't even need to load different pics. Any ideas to prevent this
from happening? Shouldn't the release actually release the memory? I
also tried creating the data separately and releasing it separately,
but that doesn't solve the leak either.
All ideas much appreciated,
Jan Van Boghout
