Many Small Images

[Avocado]

Hi everyone,

I'm wondering if anyone can point me in the right direction here... I'm working on an app that has me loading many images, about 8 KB in size, at the same time (~15 is what I'm experimenting with right now). My issue is once I've got everything loaded up, certain operations become very sluggish. Specifically, when I try to show an action sheet, it's painfully choppy.

I was originally creating the images with

[UIImage imageNamed:@"someImg.png"];

but I read that the imageNamed: method caches the images, which I don't want, so I switched to

[UIImage imageWithContentsOfFile:@"someFile"];

Unfortunately, that didn't solve the issue. Still choppy.

Any suggestions would be greatly appreciated.

Are you loading the images when drawing the screen or before?

In my app (Personal Photo Clock) I implemented a cache loading the files only once and keeping them in memory.

I also implemented a lru-list which purges the oldest unused images. I had no problem neither with scrolling or something else...
