iphone - Sort NSArray using sortedArrayUsingFunction

Question

Any good example of sorting a NSArray using sortedArrayUsingFunction ?

TY!

Answer 1

NSArray *sorted_bookings = [myUnsortedArray sortedArrayUsingFunction:Sort_Bookingdate_Comparer context:self];   

NSInteger Sort_Bookingdate_Comparer(id id1, id id2, void *context)
{
    // Sort Function
    Booking* booking1 = (Booking*)id1;  
    Booking* booking2 = (Booking*)id2;  


    return ([booking1.BOOKING_DATE compare:booking2.BOOKING_DATE]); 
}

This I used to sort bookings by bookingdate. Booking is a class with a synthesized instance variable called BOOKING_DATE.
