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 :(
