Checking for file existence:

+(BOOL)fileExistsAtAbsolutePath:(NSString*)filename {
    BOOL isDirectory;
    BOOL fileExistsAtPath = [[NSFileManager defaultManager] fileExistsAtPath:filename isDirectory:&isDirectory];

    return fileExistsAtPath && !isDirectory;
}

Checking for directory existence:

+(BOOL)directoryExistsAtAbsolutePath:(NSString*)filename {
    BOOL isDirectory;
    BOOL fileExistsAtPath = [[NSFileManager defaultManager] fileExistsAtPath:filename isDirectory:&isDirectory];

    return fileExistsAtPath && isDirectory;
}
