当用户收到推送通知时打开特定的选项卡/视图 [英] Open a specific tab/view when user receives a push notification

问题描述

我想做类似 Twitter 应用的事情:当有人给我写信时，我会收到推送通知；如果我在通知上滑动"，应用程序会启动，但不是在正常的流中，它会在特定视图中启动，并带有某人写给我的推文！

I want to do something like Twitter app: when someone write me I receive the push notification; if I "slide on the notification" the app starts, but not in the normal stream, it starts in a specific view with the tweet that someone wrote me!

在我的应用程序中，我有一个类似于 RSS 阅读器的东西，当有新消息时，推送通知就会到达.所以，我想打开单一新闻视图"，而不是主视图(现在正在发生).

In my app I have something like an RSS reader, and the push notification arrives when there is a new news. So, I want to open the "single news view", and not the main view (that's happening now).

我能做什么?

谢谢

推荐答案

您可以做两件事.

一是检查UIApplicationDelegate方法的launchOptions字典

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

查看应用是否是通过用户点击通知启动的.如果是这样，那么在该方法中，您可以将适当的视图控制器推送到堆栈上，就像您通常在应用内使用一样.

to see if the app was launched via a user clicking on a notification. If so, then in that method you can push the appropriate view controller onto the stack, just as you would normally with in-app usage.

如果应用程序已经打开，但在后台，那么同样的理论适用，但使用 UIApplicationDelegate 方法

If the app is already open, but in the background then the same theory applies but instead use the UIApplicationDelegate method

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
