How to create the “indexes” required for NSIndexPath:indexPathWithIndexes:length:

Question

The class method to create an index path with one or more nodes is:

+ (id)indexPathWithIndexes:(NSUInteger *)indexes length:(NSUInteger)length

Answer 1

You assumption is correct. It's as simple as a C array of NSUInteger. The length parameter is the number of elements in the indexes array.

Arrays in C are often identified as a pointer (in this case NSUInteger *) with a length parameter or a known terminator such as \0 for C strings (which is just a char array).
