How do I sort an NSMutableArray with custom objects in it?

Question

What I want to do seems pretty simple, but I can\'t find any answers on the web. I have an NSMutableArray of objects, and let\'s say they are \'Person\' objects

Answer 1

-(NSMutableArray*) sortArray:(NSMutableArray *)toBeSorted 
{
  NSArray *sortedArray;
  sortedArray = [toBeSorted sortedArrayUsingComparator:^NSComparisonResult(id a, id b) 
  {
    return [a compare:b];
 }];
 return [sortedArray mutableCopy];
}
