iOS CoreBluetooth后台模式通知

Question

Currently am working with the project using core bluetooth. In which am using background mode communication, am able to receive the notification when ever app running in background but we have only one service and one characteristics for data communication based on frame type we are able to identify the frames which is received.

For background mode i used this code

[centralManager connectPeripheral:activePeripheral options:@{CBConnectPeripheralOptionNotifyOnConnectionKey: @YES,
    CBConnectPeripheralOptionNotifyOnDisconnectionKey: @YES,
    CBConnectPeripheralOptionNotifyOnNotificationKey: @YES}];

its working fine for both event and session background.

Event background alert shows for every notification is there any way to hide the alert for every notification show only needed.

Thanks

In event mode the alerts are generated by the system and as long as your app is not activated, it can't do anything about them.

In session mode the app stays responsible for handling all these events. It receives all the callbacks just as in the foreground. If you want to minimize the disturbance of the user, you should take over the alert generation with this mode.
