如何知道应用用户点击推送通知ios？

Question

我想检测用户是否点击推送通知以启动app.or以将其置于前台。

Answer 1

在AppDelegate中实现方法

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

Answer 2

如果应用程序未运行，则在应用程序启动时调用didFinishLaunchingWithOptions方法，您可以检查launchOptions参数，如下所示：

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

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

    }
}

如果应用程序已经启动，您可以使用此方法：

- (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
    }
}
