ActionSheet Actions in Swift

I am new to swift and IOS development in general so I am made an Action Sheet in Xcode, but now I want to perform actions from the Action Sheet. I am familiar with doing this in ObjC by using a button Index, but I can not seem to figure this out in swift.

I would also like to customize my Action sheet to make the text different colors, but that is not as important. Please let me know if you can help. Thanks

Here is my code so far but I the .tag part of the Action when the button is pressed is wrong...

    @IBAction func ActionSheet(sender: UIButton) {

    var sheet: UIActionSheet = UIActionSheet();
    let title: String = "Action Sheet!";
    sheet.title  = title;
    sheet.addButtonWithTitle("Cancel");
    sheet.addButtonWithTitle("A course");
    sheet.addButtonWithTitle("B course");
    sheet.addButtonWithTitle("C course");
    sheet.cancelButtonIndex = 0;
    sheet.showInView(self.view);

}


func actionSheet(sheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int) {
    if (actionSheet.tag == 1) {
        NameLabel.text = "I am confused"

    }
}

I created a library that you can make it work like an action sheet view :)

You need to:

  1. Make your view controller conform to the UIActionSheetDelegate protocol:

    class ViewController: UIViewController, UIActionSheetDelegate {

  2. Add self as the delegate, and set the tag to 1:

    var sheet: UIActionSheet = UIActionSheet()
let title: String = "Action Sheet!"
sheet.title  = title
sheet.addButtonWithTitle("Cancel")
sheet.addButtonWithTitle("A course")
sheet.addButtonWithTitle("B course")
sheet.addButtonWithTitle("C course")
sheet.cancelButtonIndex = 0
sheet.delegate = self                  // new line here
sheet.tag = 1                          // another new line here
sheet.showInView(self.view)

  3. Now you can use the buttonIndex:

func actionSheet(sheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int) {
    if sheet.tag == 1 {
        println(buttonIndex)
        println(sheet.buttonTitleAtIndex(buttonIndex))
    }
}

I think your sequence is not correct, also the delegate is not set.

Declare Your class as delegate

class ViewController: UIViewController, UIActionSheetDelegate{

...

Define Action Sheet

  @IBAction func ActionSheet(sender: UIButton) {

    let actionSheet = UIActionSheet(title: "ActionSheet", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Done", otherButtonTitles: "A Course", "B Course", "C course")
    actionSheet.showInView(self.view)

}

Define Delegate Function

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

    case 0:
        NSLog("Done");
        break;
    case 1:
        NSLog("Cancel");
        break;
    case 2:
        NSLog("A Course");
        break;
    case 3:
        NSLog("B Course");
        break;
    case 4:
        NSLog("C Course");
        break;

 }
