CupertinoAlertDialog本身不带弹出效果，实现点击按钮弹出CupertinoAlertDialog的效果，代码如下：

class CupertinoAlertDialogDemo extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
return RaisedButton(
  onPressed: () {
showDialog(
    context: context,
    builder: (context) {
      return CupertinoAlertDialog(
        title: Text('删除提示'),
        content: Text('确定要删除吗？'),
        actions: <Widget>[
          FlatButton(
            child: Text('确定'),
            onPressed: () {},
          ),
        ],
      );
    });
  },
  child: Text('弹出CupertinoAlertDialog'),
);
  }
}
