Getting bundle file references / paths at app launch

You can get the URL of a file in the main bundle using

NSString *path = [[NSBundle mainBundle] pathForResource:@"SomeFile" ofType:@"jpeg"];NSURL *url = [NSURL fileURLWithPath:path];

You can write this URL to, for example, a property list file in the Documents directory:

NSString *docsDir = [NSSearchForDirectoriesInDomains(NSDocumentsDirectory, NSUserDomainMask, YES) objectAtIndex:0];NSString *plistPath = [docsDir stringByAppendingPathComponent:@"Files.plist"];NSDictionary *dict = [NSDictionary dictionaryWithObjectsAndKeys:[url absoluteString] forKey:@"SomeFile.jpeg"];[dict writeToFile:plistPath atomically:YES];

If you don't know the names of the files and you just want to list all the files in the bundle, use

NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:[[NSBundle mainBundle] bundlePath] error:NULL];for (NSString *fileName in files) {    NSString *path = [[NSBundle mainBundle] pathForResource:fileName ofType:nil];    NSURL *url = [NSURL fileURLWithPath:path];    // do something with `url`}

Or in Swift 4:

        let url = Bundle.main.url(forResource: "FileName", withExtension: ".xyz")

Yes, you would get their path:

NSString *path = [NSBundle mainBundle] pathForResource:@"file1" ofType:@"png"];NSURL *fileURL = [NSURL fileURLWithPath:path]// save it as any other object or in a dictionary:[myMutableDictionary setObject:fileURL forKey:@"file1.png"];

EDIT: to get the complete list of files, use the NSFileManager, get the path to the bundle itself, then walk each directory getting the files, making URLs, and saving them somewhere. There is oodles of code on SO how to walk a directory to do this. [You should update your question to be more specific on what you want, this was not made clear at all originally]
