使用預設選項，為指定裝置初始化新的工作階段物件。
- Parameters
-
| device | The device. |
| traits | The session traits. |
| sessionID | The session ID of an existing session, if this object will be used to resume a session; otherwise nil if it will be used to start a new session. |

初始化指定裝置的新工作階段物件。
- Parameters
-
| device | The device. |
| traits | The session traits. |
| sessionID | The session ID of an existing session, if this object will be used to resume a session; otherwise nil if it will be used to start a new session. |
| sessionOptions | The session options, if any; otherwise nil. |
- 開始時間

設定裝置音量。
這是非同步作業。預設實作為免人工管理，會導致要求失敗，並顯示 GCKErrorCodeUnsupportedFeature 錯誤。
- Parameters
-
- 傳回
- 用於追蹤要求的 GCKRequest 物件。
- 開始時間
- 3.4；在先前的架構版本中，這個方法傳回了
void。
設定裝置的靜音狀態。
這是非同步作業。預設實作為免人工管理，會導致要求失敗，並顯示 GCKErrorCodeUnsupportedFeature 錯誤。
- Parameters
-
- 傳回
- 用於追蹤要求的 GCKRequest 物件。
- 開始時間
- 3.4；在先前的架構版本中，這個方法傳回了
void。
結束包含指定動作的工作階段。
這是非同步作業。必須由子類別覆寫。
- Parameters
-
| action | The action to take when ending the session; see GCKSessionEndAction for more details. |
由「GCKSession(Protected)」類別提供。
| - (void) notifyDidStartWithSessionID: |
|
(NSString *) |
sessionID |
|
| - (void) notifyDidFailToStartWithError: |
|
(GCKError *) |
error |
|
| - (void) notifyDidEndWithError: |
|
(nullable NSError *) |
error |
| willTryToResume: |
|
(BOOL) |
willTryToResume |
|
|
| |
子類別會呼叫以通知架構，說明工作階段已結束。
- Parameters
-
| error | The error that caused the session to end, if any. Should be nil if the session was ended intentionally. |
| willTryToResume | Whether the session will try to resume itself automatically. |
由「GCKSession(Protected)」類別提供。
| - (void) notifyDidReceiveDeviceVolume: |
|
(float) |
volume |
| muted: |
|
(BOOL) |
muted |
|
|
| |
子類別會呼叫此 API，通知架構已收到裝置傳來的更新音量和靜音狀態。
- Parameters
-
| volume | The device's current volume. Must be in the range [0, 1.0]; |
| muted | The device's current mute state. |
由「GCKSession(Protected)」類別提供。
| - (void) notifyDidReceiveDeviceStatus: |
|
(nullable NSString *) |
statusText |
|
| - (GCKSessionOptions*) sessionOptions |
|
readnonatomicstrong |
| - (GCKConnectionState) connectionState |
|
