static NSDictionary* const letterValues = @{ … } in a method does not compile

Question

In a word game for iPhone:

I\'m trying to use the following code in my custom view Tile.

NSDictionary objects can't be created at compile time. However, if you need a static object, you can create one. You can, for example, use the initialize method, like this:

static NSDictionary* letterValues;

+ (void)initialize
{
    if (self == [MyClass class]) {
        letterValues = @{
                         @"A": @1,
                         @"B": @4,
                         @"C": @4,
                         @"X": @8,
                         @"Y": @3,
                         @"Z": @10,
                         };
    }
}

The if statement is there to prevent multiple calls of your code in MyClass subclasses.
