Question

Am confused with the use of this method and the documentation that lists it as a (void) method.

“on return the index path’s indexes”

where does it return anything too?

Should it not be:

- (NSIndexPath *)getIndexes:(NSUInteger *)indexes

getIndexes:
Provides a reference to the index path’s indexes.

- (void)getIndexes:(NSUInteger *)indexes

Parameters
indexes
Pointer to an unsigned integer array. On return, the index path’s indexes.
Availability
Available in iOS 2.0 and later.
Declared In
NSIndexPath.h

Answer 1

You have to allocate the NSUInteger array of size [indexPath length] and pass it as argument. The return value will be written there. You have to release that array yourself or do nothing it was created on stack like this:

NSUInteger array[[indexPath length]];
[indexPath getIndexes: array];
