Sorting array of NSDictionaries sortedArrayUsingFunction

I'm using sortedArrayUsingFunction to sort an array of NSDictionaries 
on a specific item in the dictionary. It is giving me an error of 
"selector not recognized". I thought that was the point of using a 
function, that way I was not dependant on a selector in the class.

here is what I have


@implementation MyClass

...

static int orderByName(id item1, id item2, void *context) {

   //The item name is a NSString in the dictionary
   return [[item1 objectForKey:@"name"] compare: [item2 
objectForKey:@"name"]];
   
}


-(void) someMethedThatCallsTheSort
{
...

   NSArray * sortedItems = [unsortedItems 
sortedArrayUsingFunction:orderByName context:nil];
...
}

...
@end

Can someone please let me know what I'm missing here.

Thanks for the help
