Class: NSIndexPath
Overview
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.
Class Method Summary (collapse)
-
+ indexPathWithIndex:
Creates an one-node index path.
-
+ indexPathWithIndexes:length:
Creates an index path with one or more nodes.
Instance Method Summary (collapse)
-
- compare:
Indicates the depth-first traversal order of the receiving index path and another index path.
-
- getIndexes:
Copies the objects contained in the index path into indexes.
-
- indexAtPosition:
Provides the index at a particular node in the index path.
-
- indexPathByAddingIndex:
Provides an index path containing the indexes in the receiving index path and another index.
-
- indexPathByRemovingLastIndex
Provides an index path with the indexes in the receiving index path, excluding the last one.
-
- initWithIndex:
Initializes an allocated NSIndexPath object with a one-node index path.
-
- initWithIndexes:length:
Initializes an allocated NSIndexPath object with an index path of a specific length.
-
- length
Provides the number of indexes in the index path.

Class Method Details
+ (Object) indexPathWithIndex(index)
Creates an one-node index path.
+ (Object) indexPathWithIndexes(indexes, length:length)
Creates an index path with one or more nodes.
Instance Method Details
- (NSComparisonResult) compare(indexPath)
Indicates the depth-first traversal order of the receiving index path and another index path.
- (Object) getIndexes(indexes)
Copies the objects contained in the index path into indexes. It is the developer’s responsibility to allocate the memory for the C array.
- (Integer) indexAtPosition(node)
Provides the index at a particular node in the index path.
- (NSIndexPath) indexPathByAddingIndex(index)
Provides an index path containing the indexes in the receiving index path and another index.
- (NSIndexPath) indexPathByRemovingLastIndex
Provides an index path with the indexes in the receiving index path, excluding the last one. Returns an empty NSIndexPath instance if the receiving index path’s length is 1 or less.
- (Object) initWithIndex(index)
Initializes an allocated NSIndexPath object with a one-node index path.
- (Object) initWithIndexes(indexes, length:length)
Initializes an allocated NSIndexPath object with an index path of a specific length.
- (Integer) length
Provides the number of indexes in the index path.
