Switch to the implementation file and implement a 'quotes' method which will allocate and initialize the _quotes instanc

I don't know what is wrong with my answer. Any help will be greatly appreciated. -(NSArray *) quotes{ if(_quotes == nil) { _quotes = [[NSArray alloc] initWithObjects:@"a",@"d",@"c",nil];} return _quotes; }

Please refer to the Markdown Cheatsheet on how to format your code when posting on the forum, it makes it much easier to read it! ;)

(NSArray *) quotes { 
    if (_quotes == nil) { 
        _quotes = [[NSArray alloc] initWithObjects:@"a",@"d",@"c",nil];
    } 
return _quotes; 
}

Let me have a look at this.

I have just done it once again to check and this is the correct answer: 

- (NSArray *) quotes {

  if (_quotes == nil) {
    _quotes = [[NSArray alloc] initWithObjects:@"1", @"2", @"3", nil];
  }

    return _quotes;
}

Which is exactly the same as yours, but it seems that you forgot the - before the method implementation. What that the problem?

- (NSArray *) quotes {

  if (_quotes == nil) {
    _quotes = [[NSArray alloc] initWithObjects:@"foo", @"bar", @"car", nil];
  }

    return _quotes;
}

this was my answer and its not working. Did I miss something? Looking at this forum it looks like I did it right. It's saying I'm wrong.
