I have an array containing all string values. Contents of the array are order_id, waypoint_x, waypoint_y. How do I sort it based on order_id and have the results like 1, 2, 3, 4…. (i.e. as if the field was an integer type and string)
When I use the waypoints as the array is at the moment the results come out 1, 10, 11, 12…
Regards,

If you check the documentation of NSArray, you’ll see there are different methods for sorting the array: sortedArrayUsingFunction, sortedArrayUsingSelector, sortedArrayUsingComparator, etc.
There’s a nice example of how to use sortedArrayUsingFunction to sort with integer values in the answer to this question: Sorting an array of doubles or CLLocationDistance values on the iPhone
