屏幕共享集成
屏幕共享:共享自己的手机屏幕的实时界面给其它用户,更加高效的与其它用户沟通。
共享Bundle Id相关说明
ScreenShareExtension插件bundle Id格式:
主App bundle Id + ScreenShareExtension
ScreenShareExtensionSetupUI插件bundle Id格式:
主App bundle Id + ScreenShareExtensionSetupUI
例: 主App bundle Id:com.xx.xx ScreenShareExtension插件bundIe Id:com.xx.xx.ScreenShareExtension ScreenShareExtensionSetupUI插件bundIe Id:com.xx.xx.ScreenShareExtensionSetupUI
iOS端屏幕共享需要添加iOS Extension并实现相关代码,以下步骤用于说明如何集成SDK进行屏幕共享Extension的开发。
由于相关特性对系统能力的依赖,因此需要iOS12及以上版本才能支持屏幕共享功能。详情信息参见“官方文档”。
- 创建新的Extension Target,选择
,创建Extension Target。图1 添加选择Target
图2 选择Broadcast Upload Extension,点击“Next”创建
图3 添加Broadcast Upload Extension后效果(ScreenShareExtension是创建时的名称)
- 设置Extension的支持系统版本号12.0。
图4 Extension设置
图5 ExtensionUI设置
- 给主工程和Extension添加App Groups,并设置为在开发准备中申请到的groupId。
图6 默认没有App Groups
图7 添加App Groups,选择
图8 选中App Groups,
按照上面两个图片,同理分别为ScreenShareExtension和ScreenShareExtensionSetupUI添加App Groups
图9 App Groups添加完成效果
- 分别给entitlements文件中添加App Groups ID(申请地址 此groupId在初始化的时候也会用到)
图10 应用程序添加ID效果
图11 ScreenShareExtension添加ID效果
图12 ScreenShareExtensionSetupUI添加ID效果
- 给ScreenShareExtension 添加HWMExtension.framework,添加配置
中添加-lc++。图13 选择
图14 选择HWMExtension.framework添加到Extension
图15 添加完成的效果
- 配置屏幕共享代码,Extensions 的SampleHandler.m文件中添加代码如下。
文件内容修改groupId后可以直接使用。
