the reason yours is not working is that @1969 is an NSNumber literal when it should be a string literal @"1969". also 1969 is a not valid variable name (cant start with a number).

its probably better to just set the objects and keys all in one line and not make separate variables like you did. its looks a bit redundant the way you have it now.I would do it all in one like so:

[albumMutable setObject:@"1969" forKey:@"year"];

but if you wanted to do it the way you currently have it you just need to change your variable name and make it a string literal

NSString *year = @"year";
NSString *string1969 = @"1969";
[albumMutable setObject:string1969 forKey:year"];
