FYI: If we set     currencyFormatter.internationalCurrencySymbol as well, the maximumFractionDigits performs as expected

Summary:
NSNumberFormatter ignores maximumFractionDigits after changing currencySymbol from "£" to "$" between  stringFromNumber  calls

Steps to Reproduce:
Example Code (see attached Playground as well)

// Example of issue where maximumFractionDigits doesn't get honoured after changing currency styles across usage.

// Playground - noun: a place where people can play

import UIKit

let amounts = [
    [ "amount" : 42508, "symbol" : "£"],
    [ "amount" : 317265, "symbol" : "$"]
]

let currencyFormatter = NSNumberFormatter()
currencyFormatter.numberStyle = .CurrencyStyle
currencyFormatter.maximumFractionDigits = 0

for amount in amounts {
    currencyFormatter.currencySymbol = amount["symbol"] as? String
    
    println(currencyFormatter.stringFromNumber(amount["amount"] as NSNumber))
}

Expected Results:
Expected output: 
£42,508
$317,265

Actual Results:
Actual (not the extra .00 on the second line)
£42,508
$317,265.00

Version:
iOS 8.0 Beta 5

Notes:
See attached playground for working demonstration (run on XCode 6 Beta 5).

Also not this is reproducible in Objective C and Swift. 

Configuration:
iPhone 5 running iOS8, iPhone Simulator
