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.

The "selector not recognized" error should tell you what selector is not recognized, and, as I recall, the class of the object that didn't recognize it. Care to share?
