I am creating a visual indicator.
There can be approximately up to 400 rows.
Each row can have up to 24 little images.
While in my instruments it never seems to get above 7MB on my device
when a person selects enough parameters to actually display the rows
it will eventually show up... say after about 8 secs. Then my app
becomes
unstable. Otherwise, if the parameter set is such that only about 40
rows
show up, it works great non-stop throughout the app.
I do want them to be able to scroll this list.
Thank you for your time

I am painting my iPhone scrollable view which is nested in a parent

I had originally been looping through and creating about a 1000
UIImageViews.
This worked fine and dandy on the simulator but in real life, I
think it is killing my little iPhone App.
So will just drawing the images with Quartz be that much better?
Well I figured I would try. But I am now confused on how I am
supposed to make it work.
But my scrollable view is created programatically. So what do I do
in that case?
Quartz Demo does a little work to avoid creating a new view class
for each demonstration (which may or may not be all that
advantageous in hindsight). Either way, it is probably not really
what you want in this case.
What are you trying to do? If your trying to work with 1000 images,
you almost certainly will not be able to work with them all in
memory at once (and unless they are really tiny they won't all fit
on screen at once, so having them all in memory at once is certainly
a disadvantage).
