Combining multiple NSArrays

Question

How can I combine multiple NSArrays into one array with alternating values? For example.

Array One: Orange, Apple, Pear

Array Two: Tree, Shrub, Flower

Array Three: Blue, Green, Yellow

The final array would need to be: Orange, Tree, Blue, Apple, Shrub, Green, etc

Answer 1

[@[@[@1,@2],@[@3,@4],@[@5,@6]] valueForKeyPath:@"@unionOfArrays.self"]

So once you have a array of arrays you call unionOfArrays collection operator.
