ios7 - UIActionSheet 与 swift

Question

我创建了一个action sheet，但问题是委托(delegate)方法没有被调用

 myActionSheet = UIActionSheet()
        myActionSheet.addButtonWithTitle("Add event")
        myActionSheet.addButtonWithTitle("close")
        myActionSheet.cancelButtonIndex = 1
        myActionSheet.showInView(self.view)

///UIActionSheetDelegate

func actionSheet(myActionSheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int){
        if(myActionSheet.tag == 1){

            if (buttonIndex == 0){
                println("the index is 0")
            }
        }
}

我使用了另一种适用于 iOS 8 但不适用于 iOS 7 的方法:

var ActionSheet =  UIAlertController(title: "Add View", message: "", preferredStyle: UIAlertControllerStyle.ActionSheet)

ActionSheet.addAction(UIAlertAction(title: "Add event", style: UIAlertActionStyle.Default, handler:nil))

self.presentViewController(ActionSheet, animated: true, completion: nil)

有解决问题的办法吗？

快速语言的 UIActionSheet :-

带有 cancelButton 和 destructiveButton 的操作表

设置 UIActionSheetDelegate。

        let actionSheet = UIActionSheet(title: "ActionSheet", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Done")
        actionSheet.showInView(self.view)

带有 cancelButton 、 destructiveButton 和 otherButton 的操作表

        let actionSheet = UIActionSheet(title: "ActionSheet", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: "Done", otherButtonTitles: "Yes", "No")
        actionSheet.showInView(self.view)

创建操作表函数

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

    case 0:
        NSLog("Done");
        break;
    case 1:
        NSLog("Cancel");
        break;
    case 2:
        NSLog("Yes");
        break;
    case 3:
        NSLog("No");
        break;
    default:
        NSLog("Default");
        break;
        //Some code here..

 }
