Sorting NSMutableArray of NSNumber objects
How would I sort a small NSMutableArray that has NSNumber objects. I want to arrange the array in ascending order so the smaller numbers are at the beginning of the array. I looked at the docs but there isn't much examples that are clear. Can someone provide an example?

I kind of figured it out. I used
[myArray sortUsingSelector: @selector(compare];
but could someone explains what @selector means or does?
By the way this is not for a homework assignment.

@selector gets a reference to the function/method that will be called to implement that selector name.

Assuming myArray is of type NSMutableArray
NSSortDescriptor *mySorter = [[NSSortDescriptor alloc] initWithKey:@"property_or_method_of_objects" ascending:YES]; [myArray sortUsingDescriptors:[NSArray arrayWithObject:mySorter];
