Question

I want to sort my array….
In my array elements are in this order dateArray{0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19}

But i want this array in reverse order
I used this code for reversing..

dateArray=[[NSMutableArray alloc]initWithArray:[[date reverseObjectEnumerator] allObjects]];

But it gives this output

dateArray=(
9,
8,
7,
6,
5,
4,
3,
2,
19,
18,
17,
16,
15,
14,
13,
12,
11,
10,
1,
0
)

But i want this output dateArray(19,18,17,16,15,14,13,12,11,10……..2,1,0)
I also used sorting method but output is same. how can i do this??? Please help

EDITED:

My array elements are the contents of NSDocument Directory….

Answer 1

if you are want to work with strings instead of numbers, you should use the following format for the correct sorting:

20, 19, … 10, 09, 08, … 02, 01, 00

therefore, you just have to add a leading 0 to every number. if they are strings, you can sort them like strings only, not like numbers, this is why the leading zero is needed.

by the way the most painless solution is to rename the subpaths then, where the strings come, and you won’t need to change anything else in your application for getting the right order.
