I suspect the problem is in your Word class. This should work:
NSMutableArray *myArray = [[NSMutableArray alloc] init];
NSString *word;
word = @"test0"
[myArray addObject:word];
word = @"test1"
[myArray addObject:word];
NSLog(@"Word 0: %@\nWord 1: %@", [myArray objectAtIndex:0], [myArray
objectAtIndex:1]);
I second Jonathon Mah's comments on your memory issues. It's possible
that you are not implementing setWord: or getWord properly because you
don't understand memory management yet. We might be able to help if we
saw that code.

Hello,
I try to add two object to myArray by one variable. my source code is
look like this
NSMutableArray *myArray = [[NSMutableArray alloc] init];
Word *word;
word = [[Word alloc] init];
[word setWord:@"test"];
[myArray addObject:word];
word = nil;
word = [[Word alloc] init];
[word setWord:@"test2"];
[myArray addObject:word];
Word *wd = [[myArray objectAtIndex:0] retain];
NSLog(@"word equal %@", [wd getWord]);
wd = [[myArray objectAtIndex:1] retain];
NSLog(@"word equal %@", [wd getWord]);
the result is
word equal test2
word equal test2
but It should be
word equal test
word equal test2
I am java developer, it very hard to deal with vector :(
