How to Add Uipickerview into Uialertcontroller (Alert or Actionsheet) in Swift

Is there any way to add UIPickerView into UIAlertController (Alert or ActionSheet) in Swift?

Well this is my final code which worked for me. It is a mix by a few ideas. The main reasons that I will accept my answer is that my code is in Swift, my code uses UIAlertController, my code is for picker. I want to thank to Jageen - my answer is based on his idea.

    func showPickerInActionSheet(sentBy: String) {
    var title = ""
    var message = "\n\n\n\n\n\n\n\n\n\n";
    var alert = UIAlertController(title: title, message: message, preferredStyle: UIAlertControllerStyle.ActionSheet);
    alert.modalInPopover = true;

    //Create a frame (placeholder/wrapper) for the picker and then create the picker
    var pickerFrame: CGRect = CGRectMake(17, 52, 270, 100); // CGRectMake(left), top, width, height) - left and top are like margins
    var picker: UIPickerView = UIPickerView(frame: pickerFrame);

    /* If there will be 2 or 3 pickers on this view, I am going to use the tag as a way
    to identify them in the delegate and datasource. /* This part with the tags is not required.
    I am doing it this way, because I have a variable, witch knows where the Alert has been invoked from.*/
    if(sentBy == "profile"){
        picker.tag = 1;
    } else if (sentBy == "user"){
        picker.tag = 2;
    } else {
        picker.tag = 0;
    }

    //set the pickers datasource and delegate
    picker.delegate = self;
    picker.dataSource = self;

    //Add the picker to the alert controller
    alert.view.addSubview(picker);

    //Create the toolbar view - the view witch will hold our 2 buttons 
    var toolFrame = CGRectMake(17, 5, 270, 45);
    var toolView: UIView = UIView(frame: toolFrame);

    //add buttons to the view
    var buttonCancelFrame: CGRect = CGRectMake(0, 7, 100, 30); //size & position of the button as placed on the toolView

    //Create the cancel button & set its title
    var buttonCancel: UIButton = UIButton(frame: buttonCancelFrame);
    buttonCancel.setTitle("Cancel", forState: UIControlState.Normal);
    buttonCancel.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal);
    toolView.addSubview(buttonCancel); //add it to the toolView

    //Add the target - target, function to call, the event witch will trigger the function call
    buttonCancel.addTarget(self, action: "cancelSelection:", forControlEvents: UIControlEvents.TouchDown);

    //add buttons to the view
    var buttonOkFrame: CGRect = CGRectMake(170, 7, 100, 30); //size & position of the button as placed on the toolView

    //Create the Select button & set the title
    var buttonOk: UIButton = UIButton(frame: buttonOkFrame);
    buttonOk.setTitle("Select", forState: UIControlState.Normal);
    buttonOk.setTitleColor(UIColor.blueColor(), forState: UIControlState.Normal);
    toolView.addSubview(buttonOk); //add to the subview

    //Add the tartget. In my case I dynamicly set the target of the select button
    if(sentBy == "profile"){
        buttonOk.addTarget(self, action: "saveProfile:", forControlEvents: UIControlEvents.TouchDown);
    } else if (sentBy == "user"){
        buttonOk.addTarget(self, action: "saveUser:", forControlEvents: UIControlEvents.TouchDown);
    }

    //add the toolbar to the alert controller
    alert.view.addSubview(toolView);

    self.presentViewController(alert, animated: true, completion: nil);
}

func saveProfile(sender: UIButton){
    // Your code when select button is tapped

}

func saveUser(sender: UIButton){
    // Your code when select button is tapped
}

func cancelSelection(sender: UIButton){
    println("Cancel");
    self.dismissViewControllerAnimated(true, completion: nil);
    // We dismiss the alert. Here you can add your additional code to execute when cancel is pressed
}

// returns number of rows in each component..
func pickerView(pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int{
    if(pickerView.tag == 1){
        return self.profilesList.count;
    } else if(pickerView.tag == 2){
        return self.usersList.count;
    } else  {
        return 0;
    }
}

// Return the title of each row in your picker ... In my case that will be the profile name or the username string
func pickerView(pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String! {
    if(pickerView.tag == 1){

            var selectedProfile: Profiles = self.profilesList[row] as Profiles;
            return selectedProfile.profileName;

    } else if(pickerView.tag == 2){

            var selectedUser: Users = self.usersList[row] as Users;
            return selectedUser.username;

    } else  {

        return "";

    }

}

func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
    if(pickerView.tag == 1){
            var choosenProfile: Profiles = profilesList[row] as Profiles;
            self.selectedProfile = choosenProfile.profileName;
    } else if (pickerView.tag == 2){
            var choosenUser: Profiles = usersList[row] as Users;
            self.selectedUsername = choosenUser.username;
    }

}

want to show UIPickerView in UIAlertController or UIPopoverController Swift?

below code is for UIAertController that show uipickerview. previously it give error with iPad when i make correct it for iPhone. its now work on both. iPad and iPhone.

let alertView = UIAlertController(title: "Select Launguage", message: "\n\n\n\n\n\n\n\n\n\n", preferredStyle: UIAlertControllerStyle.ActionSheet);
    if !DeviceType.IS_IPAD{
   pickerView.center.x = self.view.center.x
    }
    alertView.view.addSubview(pickerView)
    if DeviceType.IS_IPAD{
        alertView.popoverPresentationController?.sourceView = self.view
        alertView.popoverPresentationController?.sourceRect = self.pickerView.bounds
    }
    let action = UIAlertAction(title: "OK", style: UIAlertActionStyle.Default, handler: nil)

    alertView.addAction(action)
    presentViewController(alertView, animated: true, completion: nil)

for selecting device. codes are below:

enum UIUserInterfaceIdiom : Int
{
    case Unspecified
    case Phone
    case Pad
}

struct ScreenSize
{
    static let SCREEN_WIDTH         = UIScreen.mainScreen().bounds.size.width
    static let SCREEN_HEIGHT        = UIScreen.mainScreen().bounds.size.height
    static let SCREEN_MAX_LENGTH    = max(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)
    static let SCREEN_MIN_LENGTH    = min(ScreenSize.SCREEN_WIDTH, ScreenSize.SCREEN_HEIGHT)
}

struct DeviceType
{
    static let IS_IPHONE_4_OR_LESS  = UIDevice.currentDevice().userInterfaceIdiom == .Phone && ScreenSize.SCREEN_MAX_LENGTH < 568.0
    static let IS_IPHONE_5          = UIDevice.currentDevice().userInterfaceIdiom == .Phone && ScreenSize.SCREEN_MAX_LENGTH == 568.0
    static let IS_IPHONE_6          = UIDevice.currentDevice().userInterfaceIdiom == .Phone && ScreenSize.SCREEN_MAX_LENGTH == 667.0
    static let IS_IPHONE_6P         = UIDevice.currentDevice().userInterfaceIdiom == .Phone && ScreenSize.SCREEN_MAX_LENGTH == 736.0
    static let IS_IPAD              = UIDevice.currentDevice().userInterfaceIdiom == .Pad && ScreenSize.SCREEN_MAX_LENGTH == 1024.0
}

swift UIAlertController with pickerView button action stay up

Instead of adding pickerView as subview try to set contentViewController of UIAlertController like this.

let vc = UIViewController()
vc.preferredContentSize = CGSize(width: 250,height: 300)
let pickerView = UIPickerView(frame: CGRect(x: 0, y: 0, width: 250, height: 300))
pickerView.delegate = self
pickerView.dataSource = self
vc.view.addSubview(pickerView)
let editRadiusAlert = UIAlertController(title: "Choose distance", message: "", preferredStyle: UIAlertControllerStyle.alert)
editRadiusAlert.setValue(vc, forKey: "contentViewController")
editRadiusAlert.addAction(UIAlertAction(title: "Done", style: .default, handler: nil))
editRadiusAlert.addAction(UIAlertAction(title: "Cancel", style: .cancel, handler: nil))
self.present(editRadiusAlert, animated: true)

It's looks like below.

Showing a UIPickerView with UIActionSheet in iOS8 not working

From the reference for UIActionSheet:

UIActionSheet is not designed to be subclassed, nor should you add views to its hierarchy. If you need to present a sheet with more customization than provided by the UIActionSheet API, you can create your own and present it modally with presentViewController:animated:completion:.

My guess is your seeing exactly why.

The reference for UIAlertController doesn't have a similar disclaimer, but looking at its interface, my guess is Apple will add it before release.

My recommendation would be to just create a small view containing your picker and buttons and show and hide it as needed. It's not that hard to do and your not pushing interfaces beyond their intended uses.

UIPickerView within UIAlertController action sheet is not displaying any data

You're not supposed to modify the view hierarchy of a UIAlertController. Even if you could get it to work that way, you risk Apple breaking it anytime there's an update and you'd have to keep finding new workarounds to make it work. You may want to consider putting your picker in a view controller and presenting it as a UIModalPresentationPopover.
If you're using it with a responder subclass like a text field or a custom one you make, you can also make a view that looks like the action sheet with a picker and set it as the inputView of the responder.

Sizing a UIPickerView inside a UIAlertView

The trick is:

• use multiple lines for message to give space for your new view

• adjust the size of the new view when the alert view is presented

  let alertView = UIAlertController(
      title: "Select item from list",
      message: "\n\n\n\n\n\n\n\n\n",
      preferredStyle: .alert)
  
  let pickerView = UIPickerView(frame:
      CGRect(x: 0, y: 50, width: 260, height: 162))
  pickerView.dataSource = self
  pickerView.delegate = self
  
  // comment this line to use white color
  pickerView.backgroundColor = UIColor.lightGray.withAlphaComponent(0.2)
  
  alertView.view.addSubview(pickerView)
  
  let action = UIAlertAction(title: "OK", style: UIAlertActionStyle.default, handler: nil)
  
  alertView.addAction(action)
  present(alertView, animated: true, completion: { _ in
      pickerView.frame.size.width = alertView.view.frame.size.width
  })
  

Set TextField and PickerView In UIAlertView

You should create a uiviewcontroller and give it this effect.

For example: In the next image, i created a view as modal. it is a uiviewcontroller with a gray view (In your case, in the gray view you should put the uitextfield and uipickerview). Then, i configure storyboard segue as present modally and to give the effect of the modal in the uiviewcontroller put:

self.view.backgroundColor = UIColor.black.withAlphaComponent(0.8)
