ios - 使用不同的 ActionSheets Swift

Question

我目前尝试使用 2 个操作表(或可能更多)并希望对它们进行不同的操作。

 @IBAction func BTActionSheet(sender: AnyObject) {

        let action:UIActionSheet = UIActionSheet(title: "Change Map Type", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "Satelite", "Normal","Hybride")
        action.showInView(self.view)
   }

这是我用于更改 MapType 的 ActionSheet

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

    println(buttonIndex)
    if buttonIndex == 1{ Map.mapType = MKMapType.Satellite }
    if buttonIndex == 2{ Map.mapType = MKMapType.Standard }
    if buttonIndex == 3{ Map.mapType = MKMapType.Hybrid }
}

所以想添加一个 2.ActionSheet 做类似的事情

 @IBAction func BTActionSheet1(sender: AnyObject) {

        let action1:UIActionSheet = UIActionSheet(title: "secound", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "one", "two")
        action.showInView(self.view)
   }

并使用这个

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

    println(buttonIndex)
    if buttonIndex == 1{ println("otheone") }
    if buttonIndex == 2{ println("otheone2") }
}

如何检查我的 buttonIndex 来自哪个 ActionSheet？

Answer 1

您可以使用 UIActionSheet(继承自 UIView)tag属性:

 @IBAction func BTActionSheet(sender: AnyObject) {

        let action:UIActionSheet = UIActionSheet(title: "Change Map Type", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "Satelite", "Normal","Hybride")
        action.tag = 1
        action.showInView(self.view)
   }

 @IBAction func BTActionSheet1(sender: AnyObject) {

        let action1:UIActionSheet = UIActionSheet(title: "secound", delegate: self, cancelButtonTitle: "Back", destructiveButtonTitle: nil, otherButtonTitles: "one", "two")
        action1.tag = 2
        action1.showInView(self.view)
   }

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int){
    if actionSheet.tag == 1
    {
        println(buttonIndex)
        if buttonIndex == 1{ Map.mapType = MKMapType.Satellite }
        if buttonIndex == 2{ Map.mapType = MKMapType.Standard }
        if buttonIndex == 3{ Map.mapType = MKMapType.Hybrid }
    }
    if actionSheet.tag == 2
    {
        println(buttonIndex)
        if buttonIndex == 1{ println("otheone") }
        if buttonIndex == 2{ println("otheone2") }
    }
}
