Xcode IOS5 retrieve filenames

I wish to retrieve all filenames from the root directory with the extension *.gs and store them in an array.

I tried using directoryContentsAtPath.. but it says that this method has been deprecated in ios5. Do you know any alternatives?

You should use NSFileManager's:

– contentsOfDirectoryAtPath:error:

(See Apple's documentation on NSFileManager.)

You will end up with something like:

NSString *path = @"your/path";
NSError *error = nil;
NSArray *files = [[NSFileManager defaultManager] contentsOfDirectoryAtPath:path error:&error];

If you feel you don't need to check for a potential error, you may pass nil for the error argument. However, I would recommend that you check whether an error occurred and display an appropriate error message in that case. You could do it like so:

if (error) {
    // display some error message here
} else {
    // process filenames returned by NSFileManager
}
