Check out the links above. They can provide a solution to your problem.
Here is the code for you:
totalCount = 0; NSArray *d = [[NSBundle mainBundle] pathsForResourcesOfType:@"jpg" inDirectory:nil]; for(NSString *s in d) { if([[s lastPathComponent] hasPrefix:@"image_"]){ totalCount++; } }
To retrieve images from a path folder, see this: count no.of images
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 } }
