Answer 1

When you create a mutable array you have to add objects to the array. You can't set the mutable array equal to a normal array (its returned by componentsSeparatedByString:)

NSString *list = @"Norman, Stanley, Fletcher";
NSMutableArray *a2 = [[NSMutableArray alloc] init];
[a2 addObjectsFromArray:[list componentsSeparatedByString:@", "]];

NSLog(@"array is  %@",a2);
NSLog(@"array o  %@",[a2 objectAtIndex:0]);

Answer 2

Trying this

   NSArray *listItems = [list componentsSeparatedByString:@", "];
   [a2 addObject:list];
    NSLog(@"array o  %@", [a2 objectAtIndex:0]);
