刷新整个 iOS 应用 [英] Refresh the entire iOS app

我正在开发一个带有选项卡的应用程序，可以显示数据库中某个人的信息.在我的一个选项卡中有一个文本框，用户可以通过它搜索新人.

I working on an app with tabs which shows info about a person in a database. In one of my tabs there is a textbox through which a user can search for a new person.

我进行了服务器调用并获取了所有新信息，但我只是不知道如何刷新整个应用程序.任何帮助将不胜感激.

I make a server call and get all the new info but I just don't know how to refresh the entire app. Any help would be appreciated.

推荐答案

在旧数据失效时发布通知，并在新数据可用时发布通知.让你的视图控制器监听这些通知.当旧数据失效时，显示加载通知.当有新数据可用时，更新您的视图并清除所有加载通知.

Post a notification when old data is invalidated and post a notification when new data is available. Make your view controllers listen for these notifications. When old data is invalidated, show a loading notification. When new data is available, update your views and clear any loading notification.
