创建UIActionSheet

问题描述

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viewcontroller表示它，或者我必须自己获取图像并创建它。

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.

推荐答案

您需要使用 UIActionSheet 。

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

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

然后你可以引用一个动作表：

Then you can reference an actionsheet with:

  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。

Then you have to handle each of the calls.

- (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;
 }
}
