当列表中发现的设备进行更新和/或重新排序时调用。
- Parameters
-
| device | The device that was updated. |
| index | The previous list index of the device. |
| newIndex | The current list index of the device. |

- Parameters
-
| index | The list index of the device that was removed. |
| - (void) didRemoveDevice: |

|
|
| |
|
optional |
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
