Merger two array without duplication maintaing order like this:

NSArray *a= [NSArray arrayWithObjects:@"Cosmetics",@"Sample",@"test1", nil];
NSArray *b= [NSArray arrayWithObjects:@"Cosmetics",@"Sample",@"test2", nil];
NSMutableOrderedSet *setA = [NSMutableOrderedSet orderedSetWithArray:a];
NSOrderedSet *setB = [NSOrderedSet orderedSetWithArray:b];
[setA unionOrderedSet:setB];
NSLog(@"Merged One : %@", [[setA array] componentsJoinedByString:@" "]);
