iOS - Initializing an NSArray with a sequence of numbers

Question

I'm looking to do something in Objective C equivalent to the following MATLAB command:

A=4:7; 

In this case, the variable A then becomes an array with elements [4 5 6 7].

Is there any shorthand way to set an NSArray with a sequence of numbers like this in Objective C? Thanks for reading!

Answer 1

Use a NSIndexSet as the object in the array - you can then use:

[NSIndexSet indexSetWithIndexesInRange:NSMakeRange(4, 4)];
