iOS如何在UITableViewController上向屏幕中心添加视图并将其粘贴到屏幕中心？

Question

I'm working on a UITableViewController . I have to display a view with some info, that view will be added to the TableViewController programatically. This is my code of adding it:

MyNotificationView *notificationView = // some initializations;
[self.view addSubview:notificationView]; // self is the UITableViewController
notificationView.center = self.view.center;

However on UITableViewController , this code actually sets the center of my notificationView to the center of the scrollable area of the TableViewController , and my notificationView scrolls as the TableView scrolls. What I want is to add my notificationView to the screen center and stick it there, so how can this be done?

您可以创建一个UIViewController，使其内部具有UITableView，并希望将其居中放置在NotificationView中，只需将其添加到视图[self.view addSubview:notificationView];
