创建 iPhone/iOS8 弹出菜单（窗口）

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
