iOS 10推送通知-沙箱APNS问题

Question

我注意到iOS 10中有一个奇怪的推送通知问题，我建议在this SO thread中修改代码以接收推送表单沙箱APNS。

在进行这些更改之后，我将从APNS获得设备令牌，并能够接收通知。但是，如果我再次从Xcode中杀死和重新启动应用程序，则推送不起作用。如果我从设备中删除该应用程序，并将其从Xcode中再放一次，请按下“开始”。

任何人见过这种行为，并知道可能的解决办法，将是非常有帮助的。请给我建议。

下面是我的AppDelegate中一步一步的实现

步骤1:导入UserNotifications

#import <UserNotifications/UserNotifications.h>

步骤2:遵守通知协议

@interface MyAppDelegate() <UIApplicationDelegate, UNUserNotificationCenterDelegate>

application:didFinishLaunchingWithOptions: register for notification中的步骤3：

if (SYSTEM_VERSION_GREATER_THAN_OR_EQUAL_TO(@"10")) {
            UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
            center.delegate = self;
            [center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error) {
                if( !error ){
                    [[UIApplication sharedApplication] registerForRemoteNotifications];
                }
            }];
        }

步骤4:最后处理推送通知

- (void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler {
    [self handlePushNotificationWithUserInfo:response.notification.request.content.userInfo];
}

Answer 1

处理iOS 10中的通知。

有两种方法。

willPresentNotification

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
  willPresentNotification:(UNNotification *)notification  
  withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler  
{  
   NSLog( @"This method is called to Handle push from foreground" );  
  // custom code to handle push while app is in the foreground  
    NSLog(@"User info ==> %@", notification.request.content.userInfo);
}  

和didReceiveNotificationResponse

- (void)userNotificationCenter:(UNUserNotificationCenter *)center  
  didReceiveNotificationResponse:(UNNotificationResponse *)response  
  withCompletionHandler:(void (^)())completionHandler  
{  
     NSLog( @"Handle push from background or closed" );  
     NSLog(@"%@", response.notification.request.content.userInfo);
}  

希望能帮上忙！
