基本步骤

添加视图：主视图与弹出视图

关联视图

配置弹出视图

编码实现：弹出菜单样式及控制器委托

override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {

    if segue.identifier == "popoverSegue" {

        let popoverViewController = segue.destinationViewController as UIViewController

        popoverViewController.modalPresentationStyle = UIModalPresentationStyle.Popover

        popoverViewController.popoverPresentationController!.delegate = self

    }

}

编码实现：利用弹出视图控制器委托方法，定制弹出菜单的样式

func adaptivePresentationStyleForPresentationController(controller: UIPresentationController) -> UIModalPresentationStyle {

    return UIModalPresentationStyle.None

}

运行
