如何知道应用程序用户是否单击了推送通知ios？

Question

我想检测用户是否单击推送通知以启动应用程序。

Answer 1

只需在您的AppDelegate中实现方法

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

Answer 2

If the application was not running the didFinishLaunchingWithOptions method gets called when the application starts and you can check the launchOptions parameters like this:

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

    if (launchOptions != nil) {
         NSDictionary *notification = [launchOptions objectForKey:UIApplicationLaunchOptionsRemoteNotificationKey];
         if (notification) {
             // Launched from push notification
         }

    }
}

If the application is already launched you can use this method:

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    if ( application.applicationState == UIApplicationStateInactive || application.applicationState == UIApplicationStateBackground  )
    {
         //opened from a push notification when the app was on background
    }
}
