If you want to do this, you'll need to use NSFileManager
to look through the contents of [[NSBundle mainBundle] bundlePath]
(the path of your app bundle) to find all the files with the right extension.
A better question: why do you want to do this?
Edit: alright, if you insist, you'll have to do something like this:
NSEnumerator *iter = [[NSFileManager defaultManager] directoryEnumeratorAtPath:[[NSBundle mainBundle] bundlePath]];
int count = 0; // number of images
for (NSString *path in iter) { // iterate through all files in the bundle
if ([[path pathExtension] isEqualToString:@"png"]) { // test if the extension is "png"
count++; // increment the number of images
UIImage *img = [UIImage imageWithContentsOfFile:path];
// do other things with the image
}
}
