Answer 1

You can sortedArrayUsingComparator:(NSComparator)cmptr (NSArray reference) to sort the array. For instance, if you want to sort by the name property, do the following (assuming your class is called Person):

NSArray *sortedArray = [anArray sortedArrayUsingComparator:^(id a, id b) {
    NSString *first = [(Person *)a name];
    NSString *second = [(Person *)b name];
    return [first caseInsensitiveCompare:second];
}];
