新發現的裝置插入裝置清單時呼叫。
- Parameters
-
| device | The device that was inserted. |
| index | The list index at which the device was inserted. |

當先前探索的裝置更新時，會呼叫此方法。
- Parameters
-
| device | The device that was updated. |
| index | The list index of the device. |

|
optional |
先前發現的裝置更新和/或重新排序時，會呼叫此方法。
- Parameters
-
| device | The device that was updated. |
| index | The previous list index of the device. |
| newIndex | The current list index of the device. |
| - (void) didRemoveDeviceAtIndex: |
|
(NSUInteger) |
index |
|
|
optional |
當先前探索的裝置離線，且已從裝置清單中移除時，就會呼叫這個回呼。
- Parameters
-
| index | The list index of the device that was removed. |
| - (void) didRemoveDevice: |
|
(GCKDevice *) |
device |
| atIndex: |
|
(NSUInteger) |
index |
|
|
| |
|
optional |
當先前探索的裝置離線，且已從裝置清單中移除時，就會呼叫這個回呼。
這是 didRemoveDeviceAtIndex: 的替代方法。如果同時實作兩者，系統就會呼叫兩者。
- Parameters
-
| device | The device that was removed. |
| index | The list index of the device that was removed. |
- 開始時間
- 4.1
| - (void) didHaveDiscoveredDeviceWhenStartingDiscovery |
|
|
|
|
optional |
在探索程序開始之前，清單中有幾項先前探索的裝置時呼叫此方法。
自上次探索程序發現這些裝置時，這些裝置仍然有效，且尚未過期。可使用 deviceCount: 和 deviceAtIndex: 工具，取得先前探索裝置的完整清單。
- 開始時間
