Is there a way to open urls received in a push notification without opening the app in ios 10?

问题

I am trying to open a url that is passed in a push notification in ios 10. So far I haven't found a way to open a the url without opening the app. Is there a way to open urls received in a push notification without opening the app?

I have found a work-around to open the url (the work-around works for ios <10), but then again the app opens up first.

Update:

I've noticed that for the device (iOS 10.0) The following mentohds get involked application:didRegisterForRemoteNotificationsWithDeviceToken userNotificationCenter:willPresentNotification: userNotificationCenter:didReceiveNotificationResponse:

But -application:didReceiveRemoteNotification:fetchCompletionHandler: and -application:didReceiveRemoteNotification: aren't called.

I'm new to ios and this is how far I have gotten:

AppDelegate.h

#import <UIKit/UIKit.h>
#import <UserNotifications/UserNotifications.h>

@interface AppDelegate : UIResponder <UIApplicationDelegate,UNUserNotificationCenterDelegate>

@property (strong, nonatomic) UIWindow *window;


@end

AppDelegate.m

#import "AppDelegate.h"

@interface AppDelegate ()


@end

@implementation AppDelegate


- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Override point for customization after application launch.
if ([[[UIDevice currentDevice] systemVersion] floatValue] >= 10)
{
    UNUserNotificationCenter * notificationCenter = [UNUserNotificationCenter currentNotificationCenter];
    notificationCenter.delegate = self;
    [notificationCenter requestAuthorizationWithOptions:UNAuthorizationOptionAlert|UNAuthorizationOptionBadge|UNAuthorizationOptionSound completionHandler:^(BOOL granted, NSError * error)
     {
         [[UIApplication sharedApplication] registerForRemoteNotifications];
         if (error)
         {
             NSLog(@"Auth. error:%@",[error localizedDescription]);
         }
     }];
    [notificationCenter getNotificationSettingsWithCompletionHandler:^(UNNotificationSettings * settings) {

    }];

}
else
{
    UIUserNotificationType type = UIUserNotificationTypeAlert|UIUserNotificationTypeBadge|UIUserNotificationTypeSound;
    UIUserNotificationSettings * settings = [UIUserNotificationSettings settingsForTypes:type categories:nil];
    [[UIApplication sharedApplication] registerUserNotificationSettings:settings];
    [[UIApplication sharedApplication] registerForRemoteNotifications];


}

return YES;

Hopefully you can't control the behaviour of the push before launching the app. You get control over the push only after the app launched.
