my -setWord and -getWord work very well, but it will show me an error
after I get it from NSMutableArray.

>> Word *wd = [[myArray objectAtIndex:0] retain];
>> NSLog(@"word equal %@", [wa getWord]);


I think it because  "retains or copies" problems that you said. // my
basic skill is java don't know much about vector :p

this is my -setWord and -getWord

NSString *word;

- (NSString *) getWord {
   return word;
}

- (void) setWord:(NSString *)newword {
   word = newword;
}

Thank you :)
