【英文标题】：Is there a way to open urls received in a push notification without opening the app in ios 10?

【问题描述】：

我正在尝试打开一个在 ios 10 中通过推送通知传递的 url。 到目前为止，我还没有找到一种在不打开应用程序的情况下打开 url 的方法。 有没有办法在不打开应用程序的情况下打开推送通知中收到的网址？

我找到了打开 url 的变通方法（该变通方法适用于 ios

更新：

我注意到对于设备 (iOS 10.0) 调用以下方法 应用程序：didRegisterForRemoteNotificationsWithDeviceToken userNotificationCenter:willPresentNotification: userNotificationCenter:didReceiveNotificationResponse:

但是 -application:didReceiveRemoteNotification:fetchCompletionHandler: 和 -application:didReceiveRemoteNotification: 没有被调用。

我是 ios 新手，这就是我已经走了多远：

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];

【问题讨论】：

我想您可以为此使用静默推送通知。当应用程序处于后台模式时，可以在不让用户知道的情况下接收静默推送通知。请参考***.com/a/36695473/1922188

我已配置后台模式接收通知。但我希望用户单击通知，然后被重定向到 url，但没有打开应用程序。 android可以，ios可以吗？

【参考方案1】：

希望您在启动应用程序之前无法控制推送行为。只有在应用启动后，您才能控制推送。
