Answer 1

I got the answer .. But for anyone's future reference

-(IBAction)buttonPressed1:(id)sender {
     double currency = [Amount1.text doubleValue] + [Amount2.text doubleValue]; 
     NSNumberFormatter *numberFormatter = [[NSNumberFormatter alloc] init];                
     [numberFormatter setNumberStyle: NSNumberFormatterCurrencyStyle];
     NSString *numberAsString = [numberFormatter stringFromNumber:[NSNumber numberWithFloat:currency]];
     SumCurrency.text = [NSString stringWithFormat:@"Converted:%@",numberAsString]; 
}

or, in Swift:

let amount = 123.56
let formatter = NumberFormatter()
formatter.locale = Locale.current
// or
// f.locale = Locale(identifier: "it_IT")
formatter.numberStyle = .currency

let formattedAmountSting = formatter.string(for: amount)!
