My app plays audio and is allowed to run and stream in the background. Is there an option to tell Googlecast framework to keep the sockets opened?这是登录后台的日志：信息：将辞职活动信息：现在在后台罚款： - [GCKCastSocket disconnect] disconnectFINE: -[GCKCastSocket disconnect] disconnect精细： - [GCKCastSocket doTeardownWithError：] doTeardownWithErrorFINE: -[GCKCastSocket doTeardownWithError:] doTeardownWithError精细： - [GCKCastSocket doTeardownWithError：]通知委托说套接字是已断开连接FINE: -[GCKCastSocket doTeardownWithError:] notifying delegate that socket is disconnected精细： - [GCKHeartbeatChannel didDisconnect]已断开连接 - 必要时停止心跳计时器FINE: -[GCKHeartbeatChannel didDisconnect] disconnected - stopping heartbeat timer if necessary精细： - [GCKCastSocket socketDidDisconnect：withError：] socketDidDisconnect：withError：（null）FINE: -[GCKCastSocket socketDidDisconnect:withError:] socketDidDisconnect:withError: "(null)"然后当应用程序恢复时： INFO：进入前台Then when the app resumes:INFO: Going into foreground FINE： - [GCKCastSocket doTeardownWithError：] doTeardownWithErrorFINE: -[GCKCastSocket doTeardownWithError:] doTeardownWithError FINE： - [GCKCastSocket doTeardownWithError：]通知委托，套接字已断开连接FINE: -[GCKCastSocket doTeardownWithError:] notifying delegate that socket is disconnected精细： - [GCKC astSocket connectToHost：port：withTimeout：]在端口8009l上连接到192.168.1.4...FINE: -[GCKCastSocket connectToHost:port:withTimeout:] Connecting to "192.168.1.4" on port 8009l...信息：变为活动精细： - [GCKCastSocket socket：didConnectToHost：port：] socketDidConnect：FINE: -[GCKCastSocket socket:didConnectToHost:port:] socketDidConnect:精细： - [GCKCastSocket socketDidSecure：] socketDidSecure：FINE: -[GCKCastSocket socketDidSecure:] socketDidSecure:精细： - [GCKCastSocket套接字：didReadData：withTag：]前缀读取，预期消息长度= 1307FINE: -[GCKCastSocket socket:didReadData:withTag:] prefix read, expected message length=1307精细： - [GCKDeviceAuthChannel didReceiveBinaryMessage：]正版Google设备didDeviceAuthenticated = YESFINE: -[GCKDeviceAuthChannel didReceiveBinaryMessage:] Genuine Google device didDeviceAuthenticated=YES精细： - [GCKDeviceManager deviceAuthChannelDidAuthenticate：]正宗设备，连接接收器频道FINE: -[GCKDeviceManager deviceAuthChannelDidAuthenticate:] Authentic device, connecting receiver channel精细： - [GCKCastSocket套接字：didReadData：withTag：]前缀读取，预期消息长度= 474FINE: -[GCKCastSocket socket:didReadData:withTag:] prefix read, expected message length=474精细： - [GCKDeviceManager receiverControlChannel：didReceiveStatusForApplication：]应用程序到join（CC1AD845）可用FINE: -[GCKDeviceManager receiverControlChannel:didReceiveStatusForApplication:] Application to join (CC1AD845) is available FINE： - [GCKDeviceManager connectAndNotifyDidConnectToApplication：launc hedApplication：]连接到应用程序< 0x1467c8f0：GCKApplicationMetadata>默认媒体接收器（CC1AD845），传输ID web-11FINE: -[GCKDeviceManager connectAndNotifyDidConnectToApplication:launchedApplication:] Connected to application <0x1467c8f0:GCKApplicationMetadata> Default Media Receiver (CC1AD845), transport ID web-11精细： - [GCKCastSocket socket：didReadData：withTag： ]前缀读取，预期消息长度= 135FINE: -[GCKCastSocket socket:didReadData:withTag:] prefix read, expected message length=135罚款： - 收到[GCKMediaControlChannel didReceiveTextMessage：]消息：{type：MEDIA_STATUS，status：[] ，requestId：6}FINE: -[GCKMediaControlChannel didReceiveTextMessage:] message received: {"type":"MEDIA_STATUS","status":[],"requestId":6}推荐答案使用iOS Sender API 2.0版， GCKCastSocket 在收到 UIApplicationDidEnterBackgroundNotification 时关闭，这不是可以配置的东西。With the version 2.0 of the iOS Sender API, the GCKCastSocket is closed upon receiving a UIApplicationDidEnterBackgroundNotification and this is not something that can be configured.这意味着： 当应用在后台时，没有新媒体可以从应用推送到chromecast 无法实现锁定屏幕控制替代方案（仅限自定义接收方）：Alternatives (custom receiver only): 发送要播放的媒体列表到接收者 直接从接收器从云端获取新媒体参见这个问题或 this one for more details。See also this question or this one for more details. 这篇关于谷歌Chromecast SDK TearDown在后台的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
