UIActionSheet iOS Swift

Question

How To Do UIActionSheet in iOS Swift? Here is my code for coding 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)
}

I hope my Code is clear... I am welcome better suggestion for this code.

Generetic Action Sheet working for Swift 4 and 4.2

If you like a generic version that you can call from every ViewController and in every project try this one:

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)
    }
}

Call like this in your 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: Maybe you're wondering why I add Action 1/2/3 but got results like 0,1,2. In the line for (index, (title, style)) in actions.enumerated() I get the index of actions. Arrays always begin with the index 0. So the completion is 0,1,2.

If you like to set a enum, an id or another identifier I would recommend to hand over an object in parameter actions.

Action Sheet in iOS10 with Swift3.0. Follow this 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)

}

    }))

    alert.addAction(UIAlertAction(title: "Edit", style: .default , handler:{ (UIAlertAction)in

    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: {

You can use following code for open actionSheet in 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")
        })

swift4 (tested)

let alertController = UIAlertController(title: "Select Photo", message: "Select atleast one photo", preferredStyle: .actionSheet)
    let action1 = UIAlertAction(title: "From Photo", style: .default) { (action) in
        print("Default is pressed.....")
    }
    let action2 = UIAlertAction(title: "Cancel", style: .cancel) { (action) in
        print("Cancel is pressed......")
    }
    let action3 = UIAlertAction(title: "Click new", style: .default) { (action) in
        print("Destructive is pressed....")

    }
    alertController.addAction(action1)
    alertController.addAction(action2)
    alertController.addAction(action3)
    self.present(alertController, animated: true, completion: nil)

}

UIActionSheet is deprecated in iOS 8.

I am using following:

// 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)
