Jak zaprezentować UIActionSheet iOS Swift?

Jak zrobić arkusz UIActionSheet w iOS Swift? Oto mój kod do kodowania 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)
}

Mam nadzieję, że mój kod jest jasny ... Z zadowoleniem przyjmuję lepszą sugestię dotyczącą tego kodu.

Twoje podejście jest w porządku, ale możesz UIActionSheetz łatwością dodać w inny sposób.

Możesz dodać UIActionSheetDelegatejak UIViewController

class ViewController: UIViewController ,UIActionSheetDelegate

Ustaw swoją metodę, taką jak:

@IBAction func downloadSheet(sender: AnyObject)
{

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

    actionSheet.showInView(self.view)
}

Możesz uzyskać indeks swojego przycisku, gdy kliknął jak

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..

    }
}

Aktualizacja 1: dla 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)

Zaktualizowano dla Swift 4

Działa na iOS 11

Niektóre z pozostałych odpowiedzi są w porządku, ale ostatecznie wymieszałem i dopasowałem kilka z nich, aby wymyślić to:

@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")
    }))

    
    //uncomment for iPad Support
    //alert.popoverPresentationController?.sourceView = self.view

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

Ciesz się :)

UIActionSheet jest przestarzałe w iOS 8.

Używam następujących:

// 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)

Aktualizacja dla 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)

Zaktualizowano dla wersji 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")
}

Generetic Action Sheet działający dla Swift 4, 4.2, 5

Jeśli podoba Ci się ogólna wersja, do której możesz dzwonić z ViewControllerkażdego projektu, wypróbuj tę:

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)
    }
}

Wywołaj w ten sposób w swoim 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
         */
    }

Uwaga: Może zastanawiasz się, dlaczego dodaję, Action 1/2/3ale otrzymałem wyniki takie jak 0,1,2. W linii for (index, (title, style)) in actions.enumerated()otrzymuję indeks działań. Tablice zawsze zaczynają się od indeksu 0. Tak więc zakończenie wynosi 0, 1, 2.

Jeśli chcesz ustawić wyliczenie, identyfikator lub inny identyfikator, poleciłbym przekazać obiekt w parametrze actions.

Arkusz działań w iOS10 z Swift3.0. Śledź ten link.

 @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
        print("File has been Edit")
    })

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

}

Szybki:

Przykładowy kod podany poniżej działa zarówno na iPhonie, jak i iPadzie.

 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)

Stary sposób: 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 {
    ...
   }
}

Nowy sposób: 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 Do wyświetlania UIAlertController z UIBarButtonItem na iPadzie

        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")
    })
