我们可以在NSIndexPath对象中存储什么类型的数据

Question

因为我们可以在NSString对象中存储字符的集合，而在NSDictionary对象中存储键值对，所以我们可以在NSIndexpath对象中存储哪些数据类型

Answer 1

The NSIndexPath class represents the path to a specific node in a tree of nested array collections. This path is known as an index path.

Each index in an index path represents the index into an array of children from one node in the tree to another, deeper, node. For example, the index path 1.4.3.2 specifies the path in below figure

Answer 2

NSIndexpath holds typically integer values referred to as index values . These index values are wrapped up in the NSIndexPath object in some logical way so as they can be interpreted accordingly.

Example could be you require a multi-dimensional array and need to keep track of the index path to a particular element.

For iOS refer to NSIndexPath UIKit Additions

Answer 3

NSIndexPath holds an ordered list of integers referring a path through a tree.

0 entry
  0 subentry 1
  1 subentry 2
1 another entry
  0 subentry of another entry
    0 subsubentry
    1 another subsubentry
  1 another subentry of another entry

I. e. "another subsubentry" has the path 1.0.1.

Answer 4

We use NSIndexPath most commonly in UITableView methods to get section number and row number of current or selected index.If we go as an example of UITableView case it holds all section numbers in an array and holds all rows in different arrays based on number of items in section array. each section has sub array that contains rows of that section.
