You can use NSSortDescriptor like this:

NSArray* array1 = @[@"1 = off", @"10 = off", @"2 = on", @"3 = on"];
NSSortDescriptor *descriptor = [NSSortDescriptor sortDescriptorWithKey:@"" ascending:YES selector:@selector(localizedStandardCompare:)];

NSLog(@"Ordered array: %@", [array1 sortedArrayUsingDescriptors:@[ descriptor ]]);

which produces this output:

2013-06-04 12:26:22.039 EcoverdFira[3693:c07] Ordered array: (
  "1 = off",
  "2 = on",
  "3 = on",
  "10 = off"
)

There's a good article on NSSortedDescriptor's here.
