Maybe try stringByExpandingTildeInPath
something like

    NSString *path = [[NSBundle mainBundle] pathForResource:@"fileName" ofType:@"asc"];
    path = [path stringByExpandingTildeInPath];
    NSString *fileString = [NSString initWithContentsOfFile:path];

thanks for replying. I tried it, but get a warning: 'NSString' may not respond to '+initWithContentsOfFile:'

have you tried "- (id)initWithContentsOfFile:(NSString *)path encoding:(NSStringEncoding)enc error:(NSError **)error"?
