I would advise against loading all of your images into an array at once. Images tend to be large and it's easy to run out of memory and crash.

Unless you absolutely have to have all the images in memory at once it's better to keep an array of paths or URLs and load the images one at a time as needed.

Assuming the folder full of images is in your app bundle, you can use the NSBundle method URLsForResourcesWithExtension:subdirectory: to get an array of NSURLs to all the files in your images subdirectory, either with a specific filetype, or ALL files (if you pass nil for the extension.)

Once you have an array of file urls you can map it to an array of paths if needed, and then map that to an array of images.
