Get Nil When Looking for File in Subdirectory of Main Bundle

Get nil when looking for file in subdirectory of main bundle

The solution is to use

Bundle.main.url(forResource: "index", withExtension: "html", subdirectory: "games/game1")

I don't know why, but it doesn't work if we get a path, then construct an URL from it.

Note: You must

1. Copy items if needed
2. Create folder references (not "Create groups")
3. Add to targets

Bundle.main.path(forResource... always returns nil when looking for xml file

Try this code:

if let filePath = Bundle.main.url(forResource: "config.xml", withExtension: nil, subdirectory: "/Resources") {

   /// Do something with the filePath

}

Getting a subdirectory from mainBundle in xcode

The yellow folder icon for your "Objects" folder indicates that you created a folder group instead of a folder reference (those have blue folder icons) when you dragged your image folder onto the Xcode project.

Xcode copies files in a folder group into the root directory of your app bundle during the "Copy Bundle Resources" build phase.

If you want a subdirectory named "Objects" in your app bundle, you have to choose "Create folder references for any added folder" after dragging "Objects" into your Xcode window.

You projects sidebar should display the "Objects" folder as follows:

To get a list of all .pngs from that copied folder, you can use the following code:

NSURL* resourceURL = [[NSBundle mainBundle] resourceURL];
resourceURL = [resourceURL URLByAppendingPathComponent:@"Objects"];
NSError* error = nil;
NSArray* resourceURLContents = [[NSFileManager defaultManager] contentsOfDirectoryAtURL:resourceURL includingPropertiesForKeys:nil options:0 error:&error];
resourceURLContents = [resourceURLContents filteredArrayUsingPredicate:[NSPredicate predicateWithBlock:^BOOL(NSURL* evaluatedObject, NSDictionary *bindings) {
    return [[evaluatedObject pathExtension] isEqualToString:@"png"];
}]];
NSLog(@"Contents:%@", resourceURLContents);

How to get path to a subfolder in main bundle?

In Swift-3 make URL, and call appendingPathComponent:

let resourcePath = Bundle.main.resourcePath
let subdir = URL(fileURLWithPath:resourcePath!).appendingPathComponent("sub").path

or simply

let subdir = Bundle.main.resourceURL!.appendingPathComponent("sub").path

(thanks, Martin R!)

See this Q&A on information on stringByAppendingPathComponent method in Swift.

Can't find resource from Bundle

1. Click the target of project.
2. Select the item of Build Phase.
3. under Copy Bundle Resources check if your file is listed or not. If not
   listed add with the plus button.
   

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

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
}
