ios 创建 UIActionSheet

Creating UIActionSheet

提问by mbutan

I would like to create this kind of menu, of course with other menu buttons. Is there any default viewcontroller representing it, or do I have to get images and create this by myself.

我想创建这种菜单，当然还有其他菜单按钮。是否有任何默认的视图控制器代表它，或者我是否必须自己获取图像并创建它。

You need to use a UIActionSheet.

您需要使用一个UIActionSheet.

First you need to add UIActionSheetDelegateto your ViewController.h file.

首先，您需要添加UIActionSheetDelegate到 ViewController.h 文件中。

Then you can reference an actionsheet with:

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];

Then you have to handle each of the calls.

然后你必须处理每一个调用。

- (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;
 }
}

This has been deprecated for iOS 8.x https://developer.apple.com/documentation/uikit/uialertcontroller#//apple_ref/occ/cl/UIAlertController

这已被 iOS 8.x 弃用 https://developer.apple.com/documentation/uikit/uialertcontroller#//apple_ref/occ/cl/UIAlertController

Take a look at the UIActionSheetdocumentation.

查看UIActionSheet文档。

NSString *actionSheetTitle = @"Action Sheet Demo"; //Action Sheet Title
NSString *destructiveTitle = @"Destructive Button"; //Action Sheet Button Titles
NSString *other1 = @"Other Button 1";
NSString *other2 = @"Other Button 2";
NSString *other3 = @"Other Button 3";
NSString *cancelTitle = @"Cancel Button";
UIActionSheet *actionSheet = [[UIActionSheet alloc]
                              initWithTitle:actionSheetTitle
                              delegate:self
                              cancelButtonTitle:cancelTitle
                              destructiveButtonTitle:destructiveTitle
                              otherButtonTitles:other1, other2, other3, nil];
[actionSheet showInView:self.view];

It is called an UIActionSheet: You create one like so:

它被称为 UIActionSheet：您可以像这样创建一个：

    NSString *actionSheetTitle = @"Action Sheet Demo"; //Action Sheet Title
NSString *destructiveTitle = @"Destructive Button"; //Action Sheet Button Titles
NSString *other1 = @"Other Button 1";
NSString *other2 = @"Other Button 2";
NSString *other3 = @"Other Button 3";
NSString *cancelTitle = @"Cancel Button";
UIActionSheet *actionSheet = [[UIActionSheet alloc]
                              initWithTitle:actionSheetTitle
                              delegate:self
                              cancelButtonTitle:cancelTitle
                              destructiveButtonTitle:destructiveTitle
                              otherButtonTitles:other1, other2, other3, nil];
[actionSheet showInView:self.view];

Implement the UISctionSheetDelegate to respond to button action.

实现 UISctionSheetDelegate 以响应按钮操作。
