创buildiPhonepopup菜单类似于邮件应用程序菜单
我想创build一个类似于邮件应用程序中popup菜单，当你想回复一条消息。 我在一个以上的应用程序中看到了这个，所以我不确定是否在框架中有内置的东西或者代码。
查看Apple网站上的UICatalog示例。 “警报”部分提供了如何使用UIActionSheet来完成你想要做的事情的例子。
它是iOS 8+上的UIAlertController ，以及早期版本的UIActionSheet 。
在Swift中创build一个操作表
代码已经更新了Swift 3
从iOS 8开始，使用UIAlertController和UIAlertControllerStyle.ActionSheet 。 UIActionSheet已弃用。
下面是在上面的图片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: 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) } }
仍然需要帮助？ 观看这个video教程。 这就是我学到的。
- UIActionSheet在Swift中的例子 （与名称相反，它实际上使用新的
UIAlertController操作表而不是UIActionSheet。）
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];
那么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; } }
从iOS 8.x开始，这已被弃用。
这就是你如何在Objective-C的iOS 8+上做到这一点：
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];
对于所有在Swift中寻找解决scheme的人：
-
采用
UIActionSheetDelegate协议 -
创build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function：
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。 所以我一直在试图find完美的解决scheme，但一些答案让我感到困惑。 因为关于操作表的大部分问题都是很久以前写的，所以还没有更新。 无论如何…我会写旧版本的ActionSheet和更新版本的ActionSheet。 我希望我的回答能够让你的大脑和平。
