How To Do UIActionSheet in iOS Swift? Here is my code for coding UIActionSheet.

推荐答案

您的方法很好，但您可以添加 UIActionSheet 以其他方式轻松。

Your Approach is fine, but you can add UIActionSheet with other way with ease.

您可以添加 UIActionSheetDelegate 在UIViewController中像

You can add UIActionSheetDelegate in UIViewController` like

class ViewController: UIViewController ,UIActionSheetDelegate

设置类似的方法，

@IBAction func downloadSheet(sender: AnyObject) { let actionSheet = UIActionSheet(title: "Choose Option", delegate: self, cancelButtonTitle: "Cancel", destructiveButtonTitle: nil, otherButtonTitles: "Save", "Delete") actionSheet.showInView(self.view) }

单击时可以获得按钮索引

You can get your button index when it clicked like

func actionSheet(actionSheet: UIActionSheet, clickedButtonAtIndex buttonIndex: Int) { println("\(buttonIndex)") switch (buttonIndex){ case 0: println("Cancel") case 1: println("Save") case 2: println("Delete") default: println("Default") //Some code here.. } }

更新1：适用于iOS8 +

Update 1: for iOS8+

//Create the AlertController and add Its action like button in Actionsheet let actionSheetControllerIOS8: UIAlertController = UIAlertController(title: "Please select", message: "Option to select", preferredStyle: .ActionSheet) let cancelActionButton = UIAlertAction(title: "Cancel", style: .cancel) { _ in print("Cancel") } actionSheetControllerIOS8.addAction(cancelActionButton) let saveActionButton = UIAlertAction(title: "Save", style: .default) { _ in print("Save") } actionSheetControllerIOS8.addAction(saveActionButton) let deleteActionButton = UIAlertAction(title: "Delete", style: .default) { _ in print("Delete") } actionSheetControllerIOS8.addAction(deleteActionButton) self.present(actionSheetControllerIOS8, animated: true, completion: nil)
