Question

我面临通知问题。从过去12小时开始，设备中未显示通知。它早先工作了。发送到其他设备工作正常。我检查了通知中心和其他东西。已启用应用通知。

以下 http://developer.apple.com/library/ios/#technotes/tn2265/_index.html 我在iOS上启用了启用推送状态消息。

在控制台上，设备正在打印一些信息，如：

<Error>: kDataAttachStatusNotification sent, wasAttached: 1 isAttached: 1

这是什么意思？它是从服务器端收到通知而由于某种原因未能显示和接收的吗？

编辑：与itunes同步日志后。日志说的是：

您是否已请求用户授权提交通知？

尝试将以下代码添加到AppDelegate的application: didFinishLaunchingWithOptions:方法中：

夫特：

 if (UIApplication.instancesRespondToSelector(Selector("registerUserNotificationSettings:"))) {
    application.registerUserNotificationSettings(UIUserNotificationSettings(forTypes: .Alert, categories: nil))
 }

目标-C：

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    [application registerUserNotificationSettings:[UIUserNotificationSettings settingsForTypes:UIUserNotificationTypeAlert categories:nil]];
}

通知未在IOS设备中显示
