iOS/X代码 : how to know that app has been launched with a click on notification or on springboard app icon?

Question

我想知道是否有一种方法可以知道某个应用程序(可以在后台关闭或打开)是否已通过单击启动:

• 通知(在通知中心)？
• 还是跳板上的应用程序图标？

谢谢!!

把这段代码:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
    UILocalNotification *notification = launchOptions[UIApplicationLaunchOptionsLocalNotificationKey];

    if (notification) {
        // launched from notification
    } else {
        // from the springboard
    }
}

在你的UIApplicationDelegate .
