当您想回复消息时，我想创建一个类似于邮件应用程序中的弹出菜单。我在不止一个应用程序中看到过这种情况，所以我不确定框架中是否有内置的东西或一些示例代码。

在 Swift 中创建操作表
代码已经用 Swift 5 测试过
从 iOS 8 开始，使用UIAlertController组合 with UIAlertControllerStyle.ActionSheet。UIActionSheet已弃用。
这是在上图中生成操作表的代码：
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: UIAlertController.Style.actionSheet)
// blue action button
let blueAction = UIAlertAction(title: "Blue", style: UIAlertAction.Style.default) { (action) in
print("Blue action button tapped")
}
// red action button
let redAction = UIAlertAction(title: "Red", style: UIAlertAction.Style.default) { (action) in
print("Red action button tapped")
}
// yellow action button
let yellowAction = UIAlertAction(title: "Yellow", style: UIAlertAction.Style.default) { (action) in
print("Yellow action button tapped")
}
// cancel action button
let cancelAction = UIAlertAction(title: "Cancel", style: UIAlertAction.Style.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)
// present the action sheet
self.present(myActionSheet, animated: true, completion: nil)
}
}
还需要帮助吗？观看此视频教程。我就是这样学会的。
- Swift 中的 UIActionSheet 示例（与名称相反，它实际上使用新的
UIAlertController操作表而不是UIActionSheet.）

它UIAlertController在 iOS 8+ 上是 a，UIActionSheet在早期版本上是 a。

查看 Apple 网站上的 UICatalog 示例。“警报”部分提供了有关如何使用 UIActionSheet 来完成您正在尝试做的事情的示例。

您需要使用 UIActionSheet。
首先，您需要将 UIActionSheetDelegate 添加到您的 ViewController .h 文件中。
然后你可以参考一个动作表：
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];
然后您必须处理每个呼叫。
- (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;
}
}
从 iOS 8.x 开始，这已被弃用。

这就是你在 iOS 8+ 上的 Objective-C 中的做法：
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];

致所有在 Swift 中寻找解决方案的人：
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; } }

我试图在我的视图中添加 ActionSheet。所以我一直在努力寻找完美的解决方案，但有些答案让我感到困惑。因为关于Action sheet的大部分问题都是很久以前写的。而且还没有更新。无论如何...我将编写旧版本的 ActionSheet 和更新版本的 ActionSheet。我希望我的回答能够让你的大脑平静下来。
- - - - - 更新后的版本 - - - - -
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];

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

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:
