xcode - Format text field as user is typing -

-

I currently have two separate text fields in my app and I am trying to convert it to just one. Text fields are used for currency input (one pound, dollar, euro etc. and one for pence, centi etc.) and they work fine, but I need to add some functionality which will not be possible That I do not use a single field of text. Also, I think a text field is more user-friendly.

Actually I would like a text field that formats the form in the form of currency for the user in real time, while they are writing. E.g.

1 format £ 1.00 or $ 1.00 or 1.00 € etc ... as 1000 format £ 1,000.00 or $ 1,000.00 or 1 000,00 € etc ... I did

Has done some research and got some objective examples, but I do not understand how to do this in Swift (I have never programmed in Objective-C).

Any help can be greatly appreciated because I find it very disappointing.

You can use this code: 

  funk currency String FormNumber (number: double) - & gt; String {form format = NSNumberFormer () formatter.numberStyle = NSNumberFormatterStyle.CurrencyStyle formatter.currencyCode = NSLocale.currentLocale (). DisplayNameForKey (NSLocaleCurrencySymbol, value: NSLocaleCurrencyCode) return formatter.stringFromNumber (number)} Current Drive string = currency Stringformnanbr (21010) println ( "currency string: \ (currency string)") // $ 21,010.00 will print  < / Pre> 
 It is necessary that for working, extrapolation is a consistent and functional example of this information. 
 
  Import UIKit Class CurrencyTextFieldExample: UIViewController {currencyFormatter = NSNumberFormatter () Overcode Function ViewDidload () {super.viewDidLoad () // Make any additional setup after loading the view, usually Any nib TextField.addText () textField.addTarget (self, action: "Tekstfild Did Change:" For, Kantrolivents: UIControlEvents.EditingChanged) textField.frame = CGRect (x: 0, y: 40, width: 320, height: 40 ) Tekstfildkkeyboardteepe = Uykeyboardteepeknumberpd Tekstfildkbacgrundklor = Uiklorkligtgrekolor () Selfkwukaddsubviev (Tekstfild) Kurrensifaormtrknmberstyle = Nsnmberformtterstylekkurrensisyle Karrensiformterkkurrensikde = Nslokalekkarrentlokle ().

StringBeerRelipingOurrenceAustustring (printoutCertifiedContributor, withString: "") .Stringby ReplacingExecutionOffustring (CurrencyFormer.) TextField.text = CurrencyFormatter.stringFromNumber (Text as NSString) .doubleValue / 100.0)}}  
 
 I have questions if you have questions.

Is it possible to specify a dependency on another gradeal project in the granular (in android studios) outside the current project limits? For example, with a relative path like this: dependence {collection project ('../../ stdlib / dagger'}} MyApp (path / user / foo / workspace / mypad) The app (Path / User / Foo / Workspace / MyPass / App) And I have an Android Library Project with 3 subdomules: stdlib (path is / user / foo / Utilities (Path / User / Foo / Workspace / Stadlib / Utilis) http (Path / User / Foo / Workspace / Stadlib / HT) / Li> What I have to do is compile the Dagger, Util, http module in the MyApp project. The Stidelib Library module under heavy development And MyApp will grow in the form of Growth, so I do not want to push them into a Mewen repository. I am a little change. is likely to add another Gredle projects in some way? I will push the study library into the Maven repository after the source is in search of a temp...
