I have created a NSIndexPath object but when I print the value of its length property it will always show the value as 2. 

 NSIndexPath *index = [NSIndexPath indexPathForItem:0 inSection:4];

{length = 2, path = 4 - 0}

Why length is always 2?

  • length -> length of the index path itself. 4(first)-0(second). Anyway this one already covered in answers below. – MadNik Apr 07 '16 at 05:05

Because the index path is made of two indexes - the section and the item number.

  • thank you! Is there any cases where NSIndexPath having length other than 2? – rishu1992 Apr 07 '16 at 04:58
  • It will always be 2 when used with a collection view or table view. But you can use an NSIndexPath for other things as well. So it's possible to have an index path with any number of indexes. – rmaddy Apr 07 '16 at 05:02
  • if you want to change it then it can be done in this manner myIndexPath = myIndexPath.indexPathByRemovingLastIndex() – Moin Shirazi Apr 07 '16 at 05:14

basically NSIndexPath is combination of Section and Row, so it will show length as 2.
