当之前发现的设备处于离线状态并已从设备列表中移除时调用。
这是 didRemoveDeviceAtIndex: 的替代方法。如果两种方法都实现，则将调用二者。
- Parameters
-
| device | The device that was removed. |
| index | The list index of the device that was removed. |
- 开始时间
- 4.1
| - (void) didHaveDiscoveredDeviceWhenStartingDiscovery |
|
|
|
|
optional |
在发现过程开始之前，在列表中存在一些之前发现的设备时调用。
自上次发现进程发现后，这些设备仍然有效且未过期。可以使用 deviceCount: 和 deviceAtIndex: 获取之前发现的设备的完整列表。
- 开始时间
- 4.4.1

Key actions include being notified when discovery starts for a device category and when the device list is updated. Notifications are triggered when devices are inserted, updated, or removed from the list, with index information provided. The protocol also handles updates where devices are reordered in the list and when devices were already discovered before starting the discovery process. These updates provide device details and their positions within the list.\n"],null,[]]
