How to use same notification on Background Foreground in APNS - ios

Question

Im developing APNS.
When I send APNS, provide url and move the url.
APNS was succeed but When The app was running, it couldn't receive notification on foreground.
However on the background, it's work. when it's on foreground
it just move to url without notification.
Could you help me..?
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
UIApplicationState state = [UIApplication sharedApplication].applicationState;
BOOL state_active = (state == UIApplicationStateActive);
dic_apns = [userInfo objectForKey:#"aps"];
// alert export
NSString * msg = [dic_apns objectForKey:#"alert"];
NSString * eventcode = [userInfo objectForKey:#"eventcode"];
[[NSUserDefaults standardUserDefaults] setValue :msg forKey:#"push_msg"];
[[NSUserDefaults standardUserDefaults] setValue :eventcode forKey:#"eventcode"];
[[NSUserDefaults standardUserDefaults] synchronize];
NSLog(#"APNS : msg=%# | eventcode=%#", msg , eventcode);
[self goto_link];
[[UIApplication sharedApplication] setApplicationIconBadgeNumber:0];
}
-(void) goto_link{
NSString * eventcode = [[NSUserDefaults standardUserDefaults] valueForKey:#"eventcode"];
NSURL *url = [NSURL URLWithString:[NSString stringWithFormat:#"%#%#%#", _MAIN_URL, _PUSH_PARAM, eventcode]];
NSURLRequest *request = [NSURLRequest requestWithURL:url];
ViewController* main = (ViewController *) self.window.rootViewController;
if (!main.webview_sin )
{
NSLog(#"main.webView is nil!!!");
}
[main.webview_sin loadRequest:request];
}

when it's on foreground it just move to url without notification
This is the expected behaviour. Notifications aren't shown if your app is running.
You could instead use a UIAlertController to show the message to the user
-(void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
if (application.applicationState == UIApplicationStateActive)
{
UIAlertController *alertController = [UIAlertController
alertControllerWithTitle:#"Notification"
message:/* Get the message from APS */
preferredStyle:UIAlertControllerStyleAlert];
UIAlertAction *cancelAction = [UIAlertAction
actionWithTitle:#"Dismiss"
style:UIAlertActionStyleCancel
handler:^(UIAlertAction *action)
{
//Do Nothing
}];
[alertController addAction:cancelAction];
[/*pick an appropriate view controller */ presentViewController:alertController animated:YES completion:nil];
}
}
