Hello,

the following code compiles just fine, but the size of "fileArray" that
I get by using count is zero and more obviously, the code depending on
the array is never really called.
However, I know that there are "some" files in my homedirectory, which
is what I tested the code with.
Maybe someone can point out what I did wrong?

thanks in advance and greets, B.S.

My code:

- (NSMutableArray *) getFileList:(NSString *)initPath
{
    NSMutableArray * resultArray;
    NSString * fileName;
    NSFileManager * fileManager = [NSFileManager defaultManager];
// the next line creates the zero-sized array
    NSArray * fileArray = [fileManager
        directoryContentsAtPath:initPath];
    NSEnumerator * enumerator = [fileArray objectEnumerator];
    while ((fileName = [enumerator nextObject])!=nil)
    {
        NSLog(@"entered loop with fileName: %s", fileName);
        NSImage * testImage = [[NSImage alloc]
            initWithContentsOfFile:fileName];
        if(testImage != nil)
        {
            [resultArray addObject:fileName];
        }
    }
    return resultArray;
}
