objective-c why does nslog show strings inbetween double quotation marks " "?

I am开发者_JAVA百科 loading a nsarray from a textfile:

NSArray *noWords = [[NSArray alloc] initWithArray:
                        [[NSString stringWithContentsOfFile:[[NSBundle mainBundle] pathForResource:@"untitled" ofType:@"txt"]
                                                   encoding:NSUTF8StringEncoding error:NULL] componentsSeparatedByString:@"\n"]];

Untitled.txt contains:

alfa
beta (geologi).
beta
jaha
javel
jam (geologi) en
jamen
jamen
jamen
jax. (geologi)jammen
det
var
æhæhæ
øhøh
på
tide
.(geologi),be;ta;
tiden
men
but
men
aha
beta

NSLog (@"noWords : %@", noWords); shows:

2011-08-29 16:16:44.288 scanner2[30177:207] noWords : (

but,

It does that when there are spaces or other special characters in the string. Note that this is just what NSLog() does. When you do [NSString stringWithFormat:...] this doesn't happen.
