Answer 1

You can use NSDecimalNumber's decimalNumberWithString initializer to convert from a string

Answer 2

Try this:

NSString *order = @"";
if (i==1) {
  order = [feeArray objectAtIndex:0];
}
if (i==2) {
  order = [amountArray objectAtIndex:0];
}

NSDecimalNumber *decimal = [NSDecimalNumber decimalNumberWithString:order];
