Refresh Value in NSMutableDictionary using ViewWillAppear

Question

See this code:

    int i = years;
 NSLog(@"Years i: %i",i);
 NSString *syears= [NSString stringWithFormat:@"%d",i]; 

 menuList = [[NSMutableArray alloc] init]; 

 [menuList addObject:[NSMutableDictionary 
       dictionaryWithObjectsAndKeys: 
       @"years", kLeftKey, 
       syears, kRightKey, nil, kControllerKey, nil]];

The above is an extract from ViewWillAppear . When I switch between tabs ViewWillAppear is doing it's job and the data is updating down as far as NSString *syears= [NSString stringWithFormat:@"%d",i]; but after that my array doesn't get updated with the latest value of syears. I tried using setObject and setValue but these don't work with NSMutableArray . Any ideas?

Keys and values in NSDictionary need to be non- nil NSObject s. So you've definitely got an issue with a nil in there, and there may be a question about kLeftKey et al, for which you haven't shown the definitions.

More generally, it would help to know what you are doing with menuList and what you mean by "my array doesn't get updated". Are you trying to display it? Using it as a data source somewhere? You are creating the array anew here -- could a previous reference be being left around and displayed?
