Answer 1

实际上这是UIActionSheet，以下是

的代码

UIActionSheet *actionSheet;

 actionSheet = [[UIActionSheet alloc] initWithTitle:@"Choose Option" delegate:self cancelButtonTitle:@"Cancel" destructiveButtonTitle:nil otherButtonTitles: @"Rispondi",@"Rispondi a tutti",@"inoltra",@"stampa",nil];
 actionSheet.actionSheetStyle = UIActionSheetStyleBlackOpaque;
 [actionSheet showInView:self.view];
