ios 13城市飞艇后台推送失败

问题描述 投票:0回答:1

为了尝试从右脚开始,我整个上午一直在搜索SO和其他资源以寻求解决此问题的方法。

我有一个可以与无声前台推送通知以及标准推送通知完美配合的应用程序。功能设置如下

Capabilities

触发通知的JSON如下

{"device_types":["android","ios"],"notification":{"ios":{"extra":{"requests":{"directives":{"forceUpdate":1}}},"content-available":1}},"audience":{"tag":"userDevice=60218"}}

我从UA示例中将PushHandler委托减少到最低限度进行测试:

-(void)receivedBackgroundNotification:(UANotificationContent *)notificationContent completionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
// Application received a background notification
UA_LDEBUG(@"The application received a background notification");

// Call the completion handler
completionHandler(UIBackgroundFetchResultNoData);
}

-(void)receivedForegroundNotification:(UANotificationContent *)notificationContent completionHandler:(void (^)(void))completionHandler {
UA_LDEBUG(@"The application received a foreground notification %@",notificationContent);
completionHandler();
}

-(void)receivedNotificationResponse:(UANotificationResponse *)notificationResponse completionHandler:(void (^)(void))completionHandler {
UANotificationContent *notificationContent = notificationResponse.notificationContent;

NSLog(@"Received a notification response");
NSLog(@"Alert Title:         %@",notificationContent.alertTitle);
NSLog(@"Alert Body:          %@",notificationContent.alertBody);
NSLog(@"Action Identifier:   %@",notificationResponse.actionIdentifier);
NSLog(@"Category Identifier: %@",notificationContent.categoryIdentifier);
NSLog(@"Response Text:       %@",notificationResponse.responseText);

completionHandler();
}

- (UNNotificationPresentationOptions)extendPresentationOptions:(UNNotificationPresentationOptions)options notification:(UNNotification *)notification {
return options | UNNotificationPresentationOptionSound | UNNotificationPresentationOptionAlert;
} 

我还查看了设备控制台(查找x.y.z作为标识符),然后看到了:

receivedBackgroundNotification永远不会触发。

我已经检查了所有地方,似乎已经设置了所有选项(但显然没有)。感谢收到任何建议。

UPDATE

[当我将应用程序置于XCode的后台时,收到此消息:

Can't end BackgroundTask: no background task exists with identifier 106 (0x6a), or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug

在调试器中,中断发生在[UAAsyncOperation setIsFinished]中

通过设置"content-available":1,您正在使用无提示推送通知。我不确定在以前的iOS平台上是否更好,但是在iOS 13中,此类通知的APNs优先级为5(满分10)。

这意味着它们可能会被延迟,分组和突发发送,甚至被完全忽略。

例如,如果用户强行关闭应用程序(向上滑动),则完全忽略静默通知。此外,每天每个应用程序可以接收多少用户是有限制的。
