[Swift] UIActionSheetの簡単なサンプル

できること

ボタンを押すとUIActionSheetを表示して、選んだボタンのindexとタイトルを取得するだけです。

ソース

ViewController.swift

import UIKit
 
class ViewController: UIViewController, UIActionSheetDelegate {
    @IBAction func tapButton(sender : AnyObject) {
        var sheet: UIActionSheet = UIActionSheet()
        let title: String = "Please choose a plan"
        sheet.title  = title
        sheet.delegate = self
        sheet.addButtonWithTitle("Cancel")
        sheet.addButtonWithTitle("A plan")
        sheet.addButtonWithTitle("B plan")
        sheet.addButtonWithTitle("C plan")

        // キャンセルボタンのindexを指定
        sheet.cancelButtonIndex = 0

        // UIActionSheet表示
        sheet.showInView(self.view)
    }
    
    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }
 
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
 
    func actionSheet(sheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int) {
        println("index %d %@", buttonIndex, sheet.buttonTitleAtIndex(buttonIndex))
    }
}
