在Swift中创建操作表

Question

当您想要回复邮件时，我想创建一个类似于邮件应用程序中的弹出菜单。我已经在多个应用程序中看到过这个，所以我不确定框架中是否有内置的东西或者那些示例代码。

UIActionSheet example

Answer 1

在Swift中创建操作表

代码已更新为Swift 3

自iOS 8起，SELECT ProcName = COALESCE(OBJECT_NAME(St.objectid), 'Ad-Hoc'), ParentQueryText = St.Text, IndividualStatementText = SUBSTRING(St.text, (Qs.statement_start_offset / 2) + 1, ((CASE Qs.statement_end_offset WHEN -1 THEN DATALENGTH(St.text) ELSE Qs.statement_end_offset END - Qs.statement_start_offset) / 2) + 1), LastTimeRun = Qs.last_execution_time FROM sys.dm_exec_query_stats AS Qs CROSS APPLY sys.Dm_exec_sql_text(Qs.sql_handle) AS St与UIAlertController结合使用。 {@ 1}}已被弃用。

以下是在上图中生成操作表的代码：

UIAlertControllerStyle.ActionSheet

还需要帮助吗？观看此视频教程。这就是我学习它的方式。

UIActionSheet example in Swift（与名称相反，它确实使用新的UIActionSheet操作表而不是class ViewController: UIViewController { @IBOutlet weak var showActionSheetButton: UIButton! @IBAction func showActionSheetButtonTapped(sender: UIButton) { // Create the action sheet let myActionSheet = UIAlertController(title: "Color", message: "What color would you like?", preferredStyle: UIAlertControllerStyle.actionSheet) // blue action button let blueAction = UIAlertAction(title: "Blue", style: UIAlertActionStyle.default) { (action) in print("Blue action button tapped") } // red action button let redAction = UIAlertAction(title: "Red", style: UIAlertActionStyle.default) { (action) in print("Red action button tapped") } // yellow action button let yellowAction = UIAlertAction(title: "Yellow", style: UIAlertActionStyle.default) { (action) in print("Yellow action button tapped") } // cancel action button let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertActionStyle.cancel) { (action) in print("Cancel action button tapped") } // add action buttons to action sheet myActionSheet.addAction(blueAction) myActionSheet.addAction(redAction) myActionSheet.addAction(yellowAction) myActionSheet.addAction(cancelAction) // support iPads (popover view) myActionSheet.popoverPresentationController?.sourceView = self.showActionSheetButton myActionSheet.popoverPresentationController?.sourceRect = self.showActionSheetButton.bounds // present the action sheet self.present(myActionSheet, animated: true, completion: nil) } }。）

Answer 2

iOS 8+上为UIAlertController，早期版本为UIActionSheet。

Answer 3

查看Apple网站上的UICatalog示例。 “警报”部分提供了如何使用UIActionSheet来完成您要执行的操作的示例。

Answer 4

您需要使用UIActionSheet。

首先，您需要将UIActionSheetDelegate添加到ViewController .h文件中。

然后您可以使用以下内容引用操作表：

  UIActionSheet *popup = [[UIActionSheet alloc] initWithTitle:@"Select Sharing option:" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:
                        @"Share on Facebook",
                        @"Share on Twitter",
                        @"Share via E-mail",
                        @"Save to Camera Roll",
                        @"Rate this App",
                        nil];
   popup.tag = 1;
  [popup showInView:self.view];

然后你必须处理每个电话。

- (void)actionSheet:(UIActionSheet *)popup clickedButtonAtIndex:(NSInteger)buttonIndex {

  switch (popup.tag) {
    case 1: {
        switch (buttonIndex) {
            case 0:
                [self FBShare];
                break;
            case 1:
                [self TwitterShare];
                break;
            case 2:
                [self emailContent];
                break;
            case 3:
                [self saveContent];
                break;
            case 4:
                [self rateAppYes];
                break;
            default:
                break;
        }
        break;
    }
    default:
        break;
 }
}

自iOS 8.x起已被弃用。

Answer 5

这就是你在iOS 8 +上的Objective-C中的表现：

    UIAlertController *alert = [UIAlertController alertControllerWithTitle:@"Directions"
                                                                           message:@"Select mode of transportation:"
                                                                    preferredStyle:UIAlertControllerStyleActionSheet];
    UIAlertAction *drivingAction = [UIAlertAction actionWithTitle:@"Driving" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        // this block runs when the driving option is selected
    }];
    UIAlertAction *walkingAction = [UIAlertAction actionWithTitle:@"Walking" style:UIAlertActionStyleDefault handler:^(UIAlertAction * _Nonnull action) {
        // this block runs when the walking option is selected
    }];
    UIAlertAction *defaultAction = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel handler:nil];
    [alert addAction:drivingAction];
    [alert addAction:walkingAction];
    [alert addAction:defaultAction];
    [self presentViewController:alert animated:YES completion:nil];

Answer 6

对于在Swift中寻找解决方案的每个人：

采用UIActionSheetDelegate协议

创建并显示ActinSheet：

let sheet: UIActionSheet = UIActionSheet()

sheet.addButtonWithTitle("button 1")
sheet.addButtonWithTitle("button 2")
sheet.addButtonWithTitle("button 3")
sheet.addButtonWithTitle("Cancel")
sheet.cancelButtonIndex = sheet.numberOfButtons - 1
sheet.delegate = self
sheet.showInView(self.view)

委托功能：

func actionSheet(actionSheet: UIActionSheet!, clickedButtonAtIndex buttonIndex: Int){
switch buttonIndex{
    case 0:
        NSLog("button1");
    case 1:
        NSLog("button2");
    case 2:
        NSLog("button3");
    case actionSheet.cancelButtonIndex:
        NSLog("cancel");
        break;
    default:
        NSLog("blub");
        break;
  }
}

Answer 7

我尝试在我的视图中添加ActionSheet。所以我一直试图找到完美的解决方案，但一些答案让我感到困惑。因为关于行动表的大多数问题都是在很久以前写的。它还没有更新。无论如何......我将编写旧版ActionSheet和更新版本的ActionSheet。我希望我的回答能让你的大脑和平。

----------更新版本---------

    UIAlertController * alertController = [UIAlertController alertControllerWithTitle:@"Action Sheet" message:@"writeMessageOrsetAsNil" preferredStyle:UIAlertControllerStyleActionSheet];

    UIAlertAction* actionSheet01 = [UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault
                                                               handler:^(UIAlertAction * action) {  NSLog(@"OK click");}];

    UIAlertAction* actionSheet02 = [UIAlertAction actionWithTitle:@"No" style:UIAlertActionStyleDefault
                                                                 handler:^(UIAlertAction * action) {NSLog(@"OK click");}];

    UIAlertAction* actionSheet03 = [UIAlertAction actionWithTitle:@"Cancel" style:UIAlertActionStyleCancel
                                                                 handler:^(UIAlertAction * action) {
                                                                     NSLog(@"Cancel click");}];

    [browserAlertController addAction:actionSheet01];
    [browserAlertController addAction:actionSheet02];
    [browserAlertController addAction:actionSheet03];

    [self presentViewController:browserAlertController animated:YES completion:nil];

-------旧版------

UIActionSheet *actionSheet= [[UIActionSheet alloc] initWithTitle:@"Select Sharing option:" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles:@“OK”, @“NO”,@“Cancel”,
                        nil];
  actionSheet.tag = 100;
  [actionSheet showInView:self.view];

- (void)actionSheet:(UIActionSheet *)actionShee clickedButtonAtIndex:(NSInteger)buttonIndex {

  if( actionSheet.tag  == 100){
        switch (buttonIndex) {
            case 0:
                [self doSomething];
                break;
            case 1:
                [self doAnything];
                break;
            case 2:
                [self doNothing];
                break;
             default:
                break;
        }
        break;
    }
