Apple 推送通知服务,当设备离线时
当设备在线时,我在沙箱开发阶段的推送通知服务运行良好。它不断收到推送消息。
但是,如果在设备离线(无 3g 或 WiFi)时从提供商(服务器)发送消息,则设备在上线时不会收到推送消息。
对此有什么想法吗?
My push notification service in sandbox development phase works well when the device is online. It keeps getting push messages.
However if a message is sent from te provider (server) when the device is offline (no 3g or wifi), the device is not receiving the push message when it gets online.
Any thoughts on this?
