How do I get all resource paths in my bundle recursively in iOS?

Question

I have an "unzipped" folder in my application bundle. I need to get the resource paths for all files of type txt. I've been using this,

NSArray *filePaths = [NSBundle pathsForResourcesOfType:@"txt" inDirectory:[[[NSBundle mainBundle] bundlePath] stringByAppendingString:@"/unzipped"]];

But it only gets files in the first directory. Is there a recursive version of this somewhere that I'm just missing?

Your title says to get all resources paths, but the body says to only get txt so yeah a bit two sided. :-/ I came here looking for a way to get all files. — Jonny, Aug 23 '13 at 01:27
You should be able to do the same thing with the NSDirectoryEnumerator below, just remove the conditional that checks for the file type. — codeetcetera, Aug 23 '13 at 14:09

I got this working using the code posted by @rekle as a starting point. The trick is to use NSDirectoryEnumerator, which will do this recursively. Here's the function I wrote in case anyone needs it.

- (NSArray *)recursivePathsForResourcesOfType:(NSString *)type inDirectory:(NSString *)directoryPath{

    NSMutableArray *filePaths = [[NSMutableArray alloc] init];

    // Enumerators are recursive
    NSDirectoryEnumerator *enumerator = [[[NSFileManager defaultManager] enumeratorAtPath:directoryPath] retain];

    NSString *filePath;

    while ((filePath = [enumerator nextObject]) != nil){

        // If we have the right type of file, add it to the list
        // Make sure to prepend the directory path
        if([[filePath pathExtension] isEqualToString:type]){
            [filePaths addObject:[directoryPath stringByAppendingPathComponent:filePath]];
        }
    }

    [enumerator release];

    return [filePaths autorelease];
}

Swift, using NSURL

func recursivePathsForResources(type type: String) -> [NSURL] {

    // Enumerators are recursive
    let enumerator = NSFileManager.defaultManager().enumeratorAtPath(bundlePath)
    var filePaths = [NSURL]()

    while let filePath = enumerator?.nextObject() as? String {

        if NSURL(fileURLWithPath: filePath).pathExtension == type {
            filePaths.append(bundleURL.URLByAppendingPathComponent(filePath))
        }
    }

    return filePaths
}

please use `stringByAppendingPathComponent:` – Mazyod Mar 29 '14 at 18:28 — Mazyod, Mar 29 '14 at 18:28

Just an update to this method to allow any file types (nil) and provide the correct path format

- (NSArray *)recursivePathsForResourcesOfType:(NSString *)type inDirectory:(NSString *)directoryPath{

    NSMutableArray *filePaths = [[NSMutableArray alloc] init];
    NSDirectoryEnumerator *enumerator = [[NSFileManager defaultManager] enumeratorAtPath:directoryPath];

    NSString *filePath;

    while ((filePath = [enumerator nextObject]) != nil){
        if (!type || [[filePath pathExtension] isEqualToString:type]){
            [filePaths addObject:[directoryPath stringByAppendingPathComponent:filePath]];
        }
    }

    return filePaths;
}

Try something like this:

NSString *bundlePath = [[NSBundle mainBundle] bundlePath];
NSError *error = nil;
NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:bundlePath error:&error];

'files' will be an array of strings containing all the filenames in that path...

That gets all files, not just txt files, which is to be expected. but it doesn't recurse through the directories. – codeetcetera May 02 '11 at 14:37
Does not recursively visit all directories within provided path. – Zorayr Feb 22 '15 at 21:20

Swift 3.1 version of the answer from smokinggoyster

func recursivePathsForResources(type: String, in directoryPath: String) -> [String] {
    // Enumerators are recursive
    let enumerator = FileManager.default.enumerator(atPath: directoryPath)
    var filePaths: [String] = []

    while let filePath = enumerator?.nextObject() as? String {

        if URL(fileURLWithPath: filePath).pathExtension == type {
            filePaths.append(directoryPath.byAppending(pathComponent: filePath))
        }
    }
    return filePaths
}

Before copying think about create symlink. You can create just one symlink to folder with a lot of items. And it will work in most situations.

You will be free from creating another thread, waiting for end of operation, etc.
