Comment présenter UIActionSheet iOS Swift?

Comment faire UIActionSheet dans iOS Swift? Voici mon code pour coder UIActionSheet.

@IBAction func downloadSheet(sender: AnyObject)
{
    let optionMenu = UIAlertController(title: nil, message: "Choose Option", preferredStyle: .actionSheet) 

    let saveAction = UIAlertAction(title: "Save", style: .default, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Saved")
    })

    let deleteAction = UIAlertAction(title: "Delete", style: .default, handler:
    {
        (alert: UIAlertAction!) -> Void in
        println("Deleted")
    })

    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: 
    {
        (alert: UIAlertAction!) -> Void in
        println("Cancelled")
    })
    optionMenu.addAction(deleteAction)
    optionMenu.addAction(saveAction)
    optionMenu.addAction(cancelAction)
    self.presentViewController(optionMenu, animated: true, completion: nil)
}

J'espère que mon code est clair ... Je suis le bienvenu pour une meilleure suggestion pour ce code.

Votre approche est bonne, mais vous pouvez ajouter UIActionSheetfacilement d'une autre manière.

Vous pouvez ajouter UIActionSheetDelegatedans UIViewController` comme

class ViewController: UIViewController ,UIActionSheetDelegate

Définissez votre méthode comme,

@IBAction func downloadSheet(sender: AnyObject)
{

    let actionSheet = UIActionSheet(title: "Choose Option", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: nil, otherButtonTitles: "Save", "Delete")

    actionSheet.showInView(self.view)
}

Vous pouvez obtenir l'index de votre bouton quand il a cliqué comme

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int)
{
    println("\(buttonIndex)")
    switch (buttonIndex){

    case 0:
        println("Cancel")
    case 1:
        println("Save")
    case 2:
        println("Delete")
    default:
        println("Default")
        //Some code here..

    }
}

Mise à jour 1: pour iOS8 +

    //Create the AlertController and add Its action like button in Actionsheet
    let actionSheetControllerIOS8: UIAlertController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .ActionSheet)

    let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { _ in
        print("Cancel")
    }
    actionSheetControllerIOS8.addAction(cancelActionButton)

    let saveActionButton = UIAlertAction(title: "Save", style: .default)
        { _ in
           print("Save")
    }
    actionSheetControllerIOS8.addAction(saveActionButton)

    let deleteActionButton = UIAlertAction(title: "Delete", style: .default)
        { _ in
            print("Delete")
    }
    actionSheetControllerIOS8.addAction(deleteActionButton)
    self.present(actionSheetControllerIOS8, animated: true, completion: nil)

Mis à jour pour Swift 4

Fonctionne pour iOS 11

Certaines des autres réponses sont correctes mais j'ai fini par mélanger et assortir quelques-unes d'entre elles pour plutôt arriver à ceci:

@IBAction func showAlert(sender: AnyObject) {
    let alert = UIAlertController(title: "Title", message: "Please Select an Option", preferredStyle: .actionSheet)

    alert.addAction(UIAlertAction(title: "Approve", style: .default , handler:{ (UIAlertAction)in
        print("User click Approve button")
    }))

    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in
        print("User click Edit button")
    }))

    alert.addAction(UIAlertAction(title: "Delete", style: .destructive , handler:{ (UIAlertAction)in
        print("User click Delete button")
    }))

    alert.addAction(UIAlertAction(title: "Dismiss", style: .cancel, handler:{ (UIAlertAction)in
        print("User click Dismiss button")
    }))

    self.present(alert, animated: true, completion: {
        print("completion block")
    })
}

Profitez :)

UIActionSheet est obsolète dans iOS 8.

J'utilise ce qui suit:

// Create the AlertController
let actionSheetController = UIAlertController(title: "Please select", message: "How you would like to utilize the app?", preferredStyle: .ActionSheet)

// Create and add the Cancel action
let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
    // Just dismiss the action sheet
}
actionSheetController.addAction(cancelAction)

// Create and add first option action
let takePictureAction = UIAlertAction(title: "Consumer", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_customer", sender: self)
}
actionSheetController.addAction(takePictureAction)

// Create and add a second option action
let choosePictureAction = UIAlertAction(title: "Service provider", style: .Default) { action -> Void in
    self.performSegueWithIdentifier("segue_setup_provider", sender: self)
}
actionSheetController.addAction(choosePictureAction)

// We need to provide a popover sourceView when using it on iPad
actionSheetController.popoverPresentationController?.sourceView = sender as UIView

// Present the AlertController
self.presentViewController(actionSheetController, animated: true, completion: nil)

Mise à jour pour Swift 3:

// Create the AlertController and add its actions like button in ActionSheet
let actionSheetController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .actionSheet)

let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in
    print("Cancel")
}
actionSheetController.addAction(cancelActionButton)

let saveActionButton = UIAlertAction(title: "Save", style: .default) { action -> Void in
    print("Save")
}
actionSheetController.addAction(saveActionButton)

let deleteActionButton = UIAlertAction(title: "Delete", style: .default) { action -> Void in
    print("Delete")
}
actionSheetController.addAction(deleteActionButton)
self.present(actionSheetController, animated: true, completion: nil)

Mis à jour pour Swift 3.x, Swift 4.x, Swift 5.x

// create an actionSheet
let actionSheetController: UIAlertController = UIAlertController(title: nil, message: nil, preferredStyle: .actionSheet)

// create an action
let firstAction: UIAlertAction = UIAlertAction(title: "First Action", style: .default) { action -> Void in

    print("First Action pressed")
}

let secondAction: UIAlertAction = UIAlertAction(title: "Second Action", style: .default) { action -> Void in

    print("Second Action pressed")
}

let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .cancel) { action -> Void in }

// add actions
actionSheetController.addAction(firstAction)
actionSheetController.addAction(secondAction)
actionSheetController.addAction(cancelAction)


// present an actionSheet...
// present(actionSheetController, animated: true, completion: nil)   // doesn't work for iPad

actionSheetController.popoverPresentationController?.sourceView = yourSourceViewName // works for both iPhone & iPad

present(actionSheetController, animated: true) {
    print("option menu presented")
}

Feuille d'action générique fonctionnant pour Swift 4, 4.2, 5

Si vous aimez une version générique que vous pouvez appeler à partir ViewControllerde chaque projet, essayez celle-ci:

class Alerts {
 static func showActionsheet(viewController: UIViewController, title: String, message: String, actions: [(String, UIAlertActionStyle)], completion: @escaping (_ index: Int) -> Void) {
    let alertViewController = UIAlertController(title: title, message: message, preferredStyle: .actionSheet)
    for (index, (title, style)) in actions.enumerated() {
        let alertAction = UIAlertAction(title: title, style: style) { (_) in
            completion(index)
        }
        alertViewController.addAction(alertAction)
     }
     viewController.present(alertViewController, animated: true, completion: nil)
    }
}

Appelez comme ceci dans votre ViewController.

    var actions: [(String, UIAlertActionStyle)] = []
    actions.append(("Action 1", UIAlertActionStyle.default))
    actions.append(("Action 2", UIAlertActionStyle.destructive))
    actions.append(("Action 3", UIAlertActionStyle.cancel))

    //self = ViewController
    Alerts.showActionsheet(viewController: self, title: "D_My ActionTitle", message: "General Message in Action Sheet", actions: actions) { (index) in
        print("call action \(index)")
        /*
         results
         call action 0
         call action 1
         call action 2
         */
    }

Attention: Vous vous demandez peut-être pourquoi j'ajoute Action 1/2/3mais que j'ai obtenu des résultats comme 0,1,2. Dans la ligne, for (index, (title, style)) in actions.enumerated()j'obtiens l'index des actions. Les tableaux commencent toujours par l'indice 0. La complétion est donc 0,1,2.

Si vous souhaitez définir une énumération, un identifiant ou un autre identifiant, je vous recommande de remettre un objet en paramètre actions.

 @IBAction func ShowActionSheet(_ sender: UIButton) {
    // Create An UIAlertController with Action Sheet

    let optionMenuController = UIAlertController(title: nil, message: "Choose Option from Action Sheet", preferredStyle: .actionSheet)

    // Create UIAlertAction for UIAlertController

    let addAction = UIAlertAction(title: "Add", style: .default, handler: {
        (alert: UIAlertAction!) -> Void in
        print("File has been Add")
    })
    let saveAction = UIAlertAction(title: "Edit", style: .default, handler: {
        (alert: UIAlertAction!) -> Void in

    })
    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel, handler: {
        (alert: UIAlertAction!) -> Void in
        print("Cancel")
    })

    // Add UIAlertAction in UIAlertController

    optionMenuController.addAction(addAction)
    optionMenuController.addAction(saveAction)
    optionMenuController.addAction(deleteAction)
    optionMenuController.addAction(cancelAction)

    // Present UIAlertController with Action Sheet

    self.present(optionMenuController, animated: true, completion: nil)

}

Rapide :

L'exemple de code ci-dessous fonctionne à la fois sur iPhone et iPad.

 guard let viewRect = sender as? UIView else {
                return
            }

        let cameraSettingsAlert = UIAlertController(title: NSLocalizedString("Please choose a course", comment: ""), message: NSLocalizedString("", comment: ""), preferredStyle: .ActionSheet)
        cameraSettingsAlert.modalPresentationStyle = .Popover

        let photoResolutionAction = UIAlertAction(title: NSLocalizedString("Photo Resolution", comment: ""), style: .Default) { action in

        }
        let cameraOrientationAction = UIAlertAction(title: NSLocalizedString("Camera Orientation", comment: ""), style: .Default) { action in

        }
        let flashModeAction = UIAlertAction(title: NSLocalizedString("Flash Mode", comment: ""), style: .Default) { action in

        }
        let timeStampOnPhotoAction = UIAlertAction(title: NSLocalizedString("Time Stamp on Photo", comment: ""), style: .Default) { action in

        }
        let cancel = UIAlertAction(title: NSLocalizedString("Cancel", comment: ""), style: .Cancel) { action in

        }
        cameraSettingsAlert.addAction(cancel)
        cameraSettingsAlert.addAction(cameraOrientationAction)
        cameraSettingsAlert.addAction(flashModeAction)
        cameraSettingsAlert.addAction(timeStampOnPhotoAction)
        cameraSettingsAlert.addAction(photoResolutionAction)

        if let presenter = cameraSettingsAlert.popoverPresentationController {
            presenter.sourceView = viewRect;
            presenter.sourceRect = viewRect.bounds;
        }
        presentViewController(cameraSettingsAlert, animated: true, completion: nil)

L'ancienne méthode: UIActionSheet

let actionSheet = UIActionSheet(title: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Destroy", otherButtonTitles: "OK")
actionSheet.actionSheetStyle = .Default
actionSheet.showInView(self.view)

// MARK: UIActionSheetDelegate

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex  buttonIndex: Int) {
switch buttonIndex {
    ...
   }
}

La nouvelle façon: UIAlertController

let alertController = UIAlertController(title: nil, message: "Takes the appearance of the bottom bar if specified; otherwise, same as UIActionSheetStyleDefault.", preferredStyle: .ActionSheet)

let cancelAction = UIAlertAction(title: "Cancel", style: .Cancel) { (action) in
  // ...
 }
 alertController.addAction(cancelAction)

let OKAction = UIAlertAction(title: "OK", style: .Default) { (action) in
   // ...
}
alertController.addAction(OKAction)

let destroyAction = UIAlertAction(title: "Destroy", style: .Destructive) { (action) in
println(action)
}
alertController.addAction(destroyAction)

self.presentViewController(alertController, animated: true) {
// ...
}

Swift 3 Pour afficher UIAlertController depuis UIBarButtonItem sur iPad

        let alert = UIAlertController(title: "Title", message: "Please Select an Option", preferredStyle: .actionSheet)

    alert.addAction(UIAlertAction(title: "Approve", style: .default , handler:{ (UIAlertAction)in
        print("User click Approve button")
    }))

    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in
        print("User click Edit button")
    }))

    alert.addAction(UIAlertAction(title: "Delete", style: .destructive , handler:{ (UIAlertAction)in
        print("User click Delete button")
    }))

    alert.addAction(UIAlertAction(title: "Dismiss", style: UIAlertActionStyle.cancel, handler:{ (UIAlertAction)in
        print("User click Dismiss button")
    }))

    if let presenter = alert.popoverPresentationController {
        presenter.barButtonItem = sender
    }

    self.present(alert, animated: true, completion: {
        print("completion block")
    })

Utile pour remplir la liste des actions dynamiques et écouter l'action sélectionnée:

var categories = ["Science", "History", "Industry", "Agriculture"]

var handlerSelectedCategory: ((Int) -> ())?

func prepareActions(for title: String, index: Int) -> UIAlertAction {

    let alertAction = UIAlertAction(title: title, style: .default) { (action) in
        self.handlerSelectedCategory?(index)

    handlerSelectedCategory = { index in
        print(index, self.categories[index])
    }

    self.present(optionMenu, animated: true, completion: nil)

Vous pouvez utiliser le code suivant pour ouvrir actionSheet dans Swift

        let alert = UIAlertController(title: enter your title, message: "Enter your messgage. ", preferredStyle: UIAlertControllerStyle.Alert)

        alert.addTextFieldWithConfigurationHandler(configurationTextField)

        alert.addAction(UIAlertAction(title: "Close", style: UIAlertActionStyle.Cancel, handler:{ (UIAlertAction)in
            print("User click Cancel button")
        }))

        alert.addAction(UIAlertAction(title: "Ok", style: UIAlertActionStyle.Default, handler:{ (UIAlertAction)in
            print("User click Ok button")


        }))
        self.presentViewController(alert, animated: true, completion: {
            print("completion block")
        })
