Sorting Array of custom class object by date property

Question

I have an array of objects created from a custom class. Each object has an NSDate property. What is the easiest and quickest way to order all of these objects based on their dates properties? (in order from most recent to least recent).

Answer 1

NSSortDescriptor *sortDescriptor = [[NSSortDescriptor alloc] initWithKey:@"thisIsTheNameOfYourDateProperty" ascending:NO];
NSArray *orderedArray = [arrayOfCustomObjects sortedArrayUsingDescriptors:[NSArray arrayWithObject:sortDescriptor]];
