Creating UIActionSheet [duplicate]

问题:

This question already has an answer here:

• Creating iPhone Pop-up Menu Similar to Mail App Menu 7 answers

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.

You need to use a UIActionSheet.

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

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];

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;
 }
}

Take a look at the UIActionSheet documentation.

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:

    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.

What you are looking for is called an actionsheet. Read more about it here http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIActionSheet_Class/Reference/Reference.html
