Retrieve multiple images from document directory - iphone

Question

I have folder named "2" in document directory. Now in folder "2", I have five images named 0.png, 1.png, 2.png, 3.png and 4.png. I want to retrieve these images and save into an array. I have code but it returns only one image.
int b=2;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d/0.png",b]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
NSLog(#"%#",getImagePath);
imge.image=img;

Answer 1

Just use NSFileManager, something like this:
[[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];
It will give you an array with all the file paths for all files in the given path.
This is how you load the images from the array of URLs.
NSArray *paths = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];
for (NSURL *url in paths)
{
UIImage *image = [UIImage imageWithData:[NSData dataWithContentsOfURL:url]];
}

You should loop through the images.
int b=2;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSLog(#"%#",paths);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSMutableArray *images = [NSMutableArray arrayWithCapacity:5];
for (int i = 0; i < 5; i++)
{
NSString *getImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d/%d.png",b, i]];
UIImage *img = [UIImage imageWithContentsOfFile:getImagePath];
[images addObject:img];
NSLog(#"%#",getImagePath);
imge.image=img;
}
Instead of hardcoding the count and names of the image files, as Dominik suggested you should use contentsOfDirectoryAtPath:error: to get the list of files in that directory.
NSError *error = nil;
NSArray *imageFileNames = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%d",b]] error:&error];
