iOS [[NSBundle mainBundle] URLForResource:file extension:_extension] returns nil

[moonman239]

Code:

AVQueuePlayer+initWithAppAudioFiles.m

#import "AVQueuePlayer+initWithAppAudioFiles.h"

@implementation AVQueuePlayer (initWithAppAudioFiles)
+(AVQueuePlayer *)initWithAppFiles:(NSArray *)fileNames extension:(NSString *)extension
{
    NSMutableArray *fileURLs;
    for (NSString *fileName in fileNames)
    {
        NSURL *fileURL = [[NSBundle mainBundle] URLForResource:fileName withExtension:extension];
        [fileURLs addObject:fileURL];
    }
    AVQueuePlayer *queuePlayer = [[AVQueuePlayer alloc] initWithItems:fileURLs];
    return queuePlayer;
}
@end

Looks like the problem lies with the following code:

NSURL *fileURL = [[NSBundle mainBundle] URLForResource:fileName withExtension:extension];

Even though the file names and extensions are correct, fileURL remains nil.

OK, it turns out that the audio file was not located under "Copy Build Resources," which is located under "Build Phases." This is why URLForResource returned nil. Thanks, Zaph from Stack Overflow!

How did you add the files to your project? When using the File > Add Files to "ProjectName"... option (or dragging-and-dropping), you should make sure you have checked the proper target in the "Add to targets" section of the dialog. If so, this will automatically add the file to the Copy Bundle Resources settings.
