You need to add grouping Size to 3 :

NSNumberFormatter *formatter1 = [NSNumberFormatter new];
[formatter1 setUsesGroupingSeparator: YES];
[formatter1 setGroupingSeparator: @","];
[formatter1 setGroupingSize: 3];

NSString *numberString = [formatter1 stringFromNumber: [NSNumber numberWithInteger: 1000000]];
