Objective-C: trimming whitespace

Question

I have to be missing something. I'm trying to trim the data being pulled from an array but my app crashes on the trim method.

                //pull values
 NSString* thisXStr = [thisSetArray objectAtIndex:0];
 NSString* thisYStr = [thisSetArray objectAtIndex:1];

 //cleaning up all the white space
 NSString *thisXStrTrim = [thisXStr stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];
 NSString *thisYStrTrim = [thisYStr stringByTrimmingCharactersInSet: [NSCharacterSet whitespaceAndNewlineCharacterSet]];

Answer 1

Try to make a copy of the array objects: NSString *thisXStr = [NSString stringWithString:[thisSetArray objectAtIndex:0]]; ...

Answer 2

Crap, never mind, stupid syntax error on a NSLog...
