Concatenate one NSMutableArray to the end of another NSMutableArray.

Question

Hello everyone!

A simple answer to this super simple question would be great! Here is the pseudcode:

NSMutableArray Africa = [Lion, Tiger, Zebra];
NSMutableArray Canada = [Polar Bear, Beaver , Loon];

NSMutable Array Animals = Africa + Canada;

What I want to end up with:

Animals = [Lion, Tiger, Zebra, Polar Bear, Beaver, Loon];

What is the proper syntax to achieve this in Objective-C/ Cocoa?

Thanks so much!

To create an array:

NSMutableArray* africa = [NSMutableArray arrayWithObjects: @"Lion", @"Tiger", @"Zebra", nil];
NSMutableArray* canada = [NSMutableArray arrayWithObjects: @"Polar bear", @"Beaver", @"Loon", nil];

To combine two arrays you can initialize array with elements of the 1st array and then add elements from 2nd to it:

NSMutableArray* animals = [NSMutableArray arrayWithArray:africa];
[animals addObjectsFromArray: canada];
