问题描述

我已经创建了一个应用程序中获取后台code被写入在接收到推送通知。我已启用的的.plist后台模式，内容可用的键值设置为1推送通知的有效载荷，注册推送通知，并使用委托

I have created an app in which background fetch code is written on receiving push notification. I have enabled the background mode in .plist, content-available key is set to 1 in push notification payload, registered for push notification and using delegate

 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo fetchCompletionHandler:(void (^)(UIBackgroundFetchResult result))completionHandler  

现在，当我的应用程序是在后台，我接到一个电话。
通话过程中，我收到了我的应用程序推送通知。结果
在通话过程中收到推送通知，推送通知委托不获取调用。

Now when my app is in background, I receive a call. During call, I receive a push notification for my app.
On receiving the push notification during a call, push notification delegate is not getting called.

推荐答案

我电话手机芯片被用于语音传输过程中猜测。数据传输是为芯片做可能影响电池的寿命显着的额外工作。这是在电话更受苹果意识的决定，使之更无声的通​​知。

I guess during phone call cellular chip is being used for voice transmission. Data transmission is extra work for the chip to do which could affect battery life dramatically. This is a more a conscious decision by Apple to make it more of a silent notification during phone calls.
