如何处理点击推送通知 ios

Question

我设法收到推送通知，但我不知道如何处理到达应用程序的推送通知上的点击，我想根据通知类型告诉应用程序何时点击 go 进行特定活动，而不仅仅是打开应用程序（默认行为）

我知道我可以收到

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

    NSLog(@"Here I should Recive The notification .... ") ;
    //call the commented functions .....
}

在这个 function 中，但是当我执行它时，通知不会出现，只是在这个 function 中执行操作

对于在 2022 年遇到此问题的任何人，这是一个可行的解决方案。 连接推送通知服务后，您需要在 AppDelegate 中实现 didReceive function 并获取通知内容：

func userNotificationCenter(_ center: UNUserNotificationCenter,
                            didReceive response: UNNotificationResponse,
                            withCompletionHandler completionHandler: @escaping () -> Void) {
    let userInfo = response.notification.request.content.userInfo
    let title = response.notification.request.content.title
    let message = response.notification.request.content.body
    userDefaultsManager.savePushNotificationData(pushNotificationData: ["title" : title, "message" : message])
}

请注意，如果您需要在推送本身中获取自定义数据，它将存储在 userInfo 中。 你可以这样得到它：

func userNotificationCenter(_ center: UNUserNotificationCenter,
                        didReceive response: UNNotificationResponse,
                        withCompletionHandler completionHandler: @escaping () -> Void) {
     let userInfo = response.notification.request.content.userInfo
     let url = userInfo["url"]
}

尝试处理此点击，如代码所示，

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

//Accept push notification when the app is not open.
        if (remoteNotifiInfo) {
            [self application:application didReceiveRemoteNotification: remoteNotifiInfo];
        }

}



   // On click of notification open related screen.

像这样覆盖didReceiveRemoteNotification

- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
        {
                    UIApplicationState state = [[UIApplication sharedApplication] applicationState];
                    if ( state == UIApplicationStateInactive )
                    {
                        //Your actions on notification click
                        double delayInSeconds = 0.3;
                        dispatch_time_t popTime = dispatch_time(DISPATCH_TIME_NOW, delayInSeconds * NSEC_PER_SEC);
                        dispatch_after(popTime, dispatch_get_main_queue(), ^(void){
                            //code to be executed on the main queue after delay
                            [[NSNotificationCenter defaultCenter] postNotificationName:@"pushTOEventDetails" object:eventVO];
                        });

                    }
        }

如果您想通过点击pushnotification来导航某些特定的ViewController，只需在didReceiveRemoteNotification中添加ViewController导航代码

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

NSLog(@"Here I should Receive The notification .... ") ;
//call the commented functions .....

FirstController *firstviewcontroller = [[FirstController alloc] initWithNibName:@"FirstController" bundle:nil];

    [self.navigationController pushviewcontroller:firstviewcontroller animated:YES];

}

仅当应用程序处于活动状态时，该委托方法才会被触发。 如果应用程序未运行，则应该使用委托方法application:didFinishLaunchingWithOptions:中的launchOptions获取通知有效负载，并根据有效负载进行导航。
