Swift UIActionSheet crashes on iPad?

Question

I m currently running into complete frustrations as i can't find any error, but my ActionSheet crashes on iPad but works well on iPhone here is the code of the action

if (view.annotation.title as String!) == "San Francisco" {

                currentLat = 37.615223
                    currentLong = -122.389977

                url = "www.google.de"

                let action:UIActionSheet = UIActionSheet(title: "Change Map Type", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "Product Page", "Video")
                action.showInView(self.view)
                action.tag = 0
                VideoID = "XXXXXX"


            }

So the action that should be handled is

if actionSheet.tag == 0{
            if buttonIndex == 1{ performSegueWithIdentifier("showShop", sender: self) }
            if buttonIndex == 2{ UIApplication.sharedApplication().openURL(NSURL(string: "http://www.youtube.com/watch?v=\(youtubeVideoID)")) }
            //if buttonIndex == 2{ performSegueWithIdentifier("showYoutube", sender: self) }

        }

The Youtube one works fine, on iPhone and iPad, the "showShop" does work fine on iPhone but not on iPad

The "showShop" Segue forward to my ViewControllerShopView that looks like

import UIKit

class ViewControllerShopView: UIViewController {
/* ################################################## IBOutlets ################################################## */
    @IBOutlet weak var activity3: UIActivityIndicatorView!
    @IBOutlet weak var webView: UIWebView!
/* ################################################## viewDidLoad ################################################## */
    override func viewDidLoad() {
        super.viewDidLoad()

        loadurl()
    }
/* ################################################## didReceiveMemoryWarning ################################################## */
    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()

        println("memory warning")
    }
/* ################################################## viewWillAppear ################################################## */
    override func viewWillAppear(animated: Bool) {

        loadurl()
    }
/* ################################################## loadurl func ################################################## */
    func loadurl(){
        var loadingurl = "google.com"
        var homeurl = "google1.com"
        loadingurl = url
        let webviewURL = NSURL(string: loadingurl)
        let request = NSURLRequest(URL: webviewURL)
        webView.loadRequest(request)
    }
/* ################################################## HomeButton ################################################## */
    @IBAction func Reload(sender: AnyObject) {

        var loadingurl = "google.com"
        var homeurl = "google1.com"
        loadingurl = url
        let webviewURL = NSURL(string: loadingurl)
        let request = NSURLRequest(URL: webviewURL)
        webView.loadRequest(request)
    }
/* ################################################## Activity Indicator ################################################## */
    func webViewDidStartLoad(_ : UIWebView){activity3.startAnimating()}
    func webViewDidFinishLoad(_ : UIWebView){activity3.stopAnimating()}



}

but the Segue never been done on iPad, it simply crashes on the Segue.

Anyone a idea what could be wrong?

Answer 1

you need to check the system version in runtime if your project supports both iOS7 and iOS8; you can insert this snippet into any of your methods:

let systemVersion: NSInteger = (UIDevice.currentDevice().systemVersion as NSString).integerValue
if systemVersion < 8 {
    // iOS7:
    let action:UIActionSheet = UIActionSheet(title: "Change Map Type", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "Product Page", "Video")
    action.tag = 0
    action.showInView(self.view)
} else {
    // iOS8:
    let alertController: UIAlertController = UIAlertController(title: "Change Map Type", message: nil, preferredStyle: UIAlertControllerStyle.ActionSheet)
    let cancelAction: UIAlertAction = UIAlertAction(title: "Back", style: UIAlertActionStyle.Cancel, handler: nil)
    let button1action: UIAlertAction = UIAlertAction(title: "Product Page", style: UIAlertActionStyle.Default, handler: { (action: UIAlertAction!) -> () in
        // doing something for "product page"
    })
    let button2action: UIAlertAction = UIAlertAction(title: "Video", style: UIAlertActionStyle.Default, handler: { (action: UIAlertAction!) -> () in
        // doing something for "video"
    })
    alertController.addAction(cancelAction)
    alertController.addAction(button1action)
    alertController.addAction(button2action)

    // for iPAD support:
    alertController.popoverPresentationController?.sourceView = self.view
    alertController.popoverPresentationController?.sourceRect = CGRectMake(self.view.bounds.width / 2.0, self.view.bounds.height / 2.0, 1.0, 1.0) // this is the center of the screen currently but it can be any point in the view

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

and your class needs to conform the UIActionSheetDelegate for the UIActionSheet class:

extension ViewController : UIActionSheetDelegate {

    func actionSheet(actionSheet: UIActionSheet, didDismissWithButtonIndex buttonIndex: Int) {

        if actionSheet.tag == 0 {
            if buttonIndex == 1 {
                // doing something for "product page"
            } else if (buttonIndex == 2) {
                // doing something for "video"
            }
        }
    }

}

Answer 2

also tried this

@IBAction func BTfindme(sender: AnyObject) {
        let actionSheetController: UIAlertController = UIAlertController(title: "Action Sheet", message: "Test", preferredStyle: .ActionSheet)
        let cancelAction: UIAlertAction = UIAlertAction(title: "Cancel", style: .Cancel) { action -> Void in
            }
        actionSheetController.addAction(cancelAction)

        let ActionOne: UIAlertAction = UIAlertAction(title: "Action one", style: .Default) { action -> Void in
            }
        actionSheetController.addAction(ActionOne)

        let ActionTwo: UIAlertAction = UIAlertAction(title: "Action two", style: .Default) { action -> Void in
            }
        ActionTwo.addAction(choosePictureAction)
        self.presentViewController(actionSheetController, animated: true, completion: nil)
    }

and this also force a crash on ipad but not on iphone
