//You have two NSArrays and you want to merge them into 1 Array.
//Easy. You need to know about NSSet and maybe a little 'Set Theory'.
NSMutableSet *mergedSet = [NSMutableSet setWithArray:arrayFirst];
[mergedSet unionSet:[NSSet setWithArray:arraySecond]];

//In Set Theory, a union will automatically remove your duplicates. In the case you only wanted to know about duplicates, then take a look at intersectSet:
//Take your new set one step further by sorting them alphabetically with a block:

arraySorted = [[mergedSet allObjects] sortedArrayUsingComparator:^NSComparisonResult(id a, id b) {
