开发工具：Xcode 功能需要: SwiftUI实现UI页面，iOS16.1以上系统使用
功能使用: 需应用为启动状态
功能说明
iOS16.1 系统支持实时活动功能，可以在锁定屏幕上实时获知各种事情的进展，MobPushSDK iOS 4.0.3版本已完成适配，可根据文档对应使用。
集成步骤
添加依赖库
ActivityKit.farework
SwiftUI.farework
配置⼯程⽀持 LiveActivity
在主⼯程的 Info.plist ⽂件中添加⼀个键值对，key 为 NSSupportsLiveActivities，value 为 YES
添加实时活动扩展
添加扩展项目依赖库
UI实现
实时活动UI需开发者自行实现，可参考Demo处理，注意需将扩展的UI组件引用到主项目上
实时活动API
上传实时活动token registerLiveActivityWithID（）
示例代码：
/*!* @abstract 注册LiveActivity并上报PushToken* 在PushToken更新时，需同步调用该接口* 在LiveActivity结束时，需同步调用该接口，PushToken为nil** @param liveActivityId 标识某一个LiveActivity* @param pushToken 对应LiveActivity的PushToken* @param handler 结果回调*/[MobPush registerLiveActivityWithID:@"mpLiveActivity"pushToken:tokencompletion:^(NSError *error) {if (error) {NSLog(@"Register LiveActivity Failed: %@", error.localizedDescription);}}];}
活动开始startActivity（）
示例代码：
static public func startActivity(pushTokenUpdate:@escaping (Bool, Data?)->Void) {guard ActivityAuthorizationInfo().areActivitiesEnabled else {//不可用pushTokenUpdate(false, nil)//监听可用状态
// for await enablment in ActivityAuthorizationInfo().activityEnablementUpdates {
// print("Activity AuthorizationInfo change to (enablment)")
// }return}endPreActivity()let state = HeartNoteLiveActivitsLiveAttributes.ContentState(prograssState: .Car)let attri = HeartNoteLiveActivitsLiveAttributes(name: "MPLiveActivities")do {let current = try Activity.request(attributes: attri, contentState: state, pushType: .token)Task {for await tokenData in current.pushTokenUpdates {//监听token更新 注意线程pushTokenUpdate(true, tokenData)}}Task {for await state in current.contentStateUpdates {//监听state状态 开发者可自行编写回调监听print("1content state update: tip=(state.prograssState)")}}Task {//监听activity状态 开发者可自行编写回调监听for await state in current.activityStateUpdates {print("activity state update: tip=(state) id:(current.id)")}}} catch(let error) {print("error=",error)pushTokenUpdate(false, nil)}}
更新Activity状态updateActivityState（）
static public func updateActivityState(_ value: Int) {Task {guard let current = Activity<HeartNoteLiveActivitsLiveAttributes>.activities.first else {return}let state = HeartNoteLiveActivitsLiveAttributes.ContentState(prograssState: PrograssState(rawValue: value) ?? .Arrived)let alertConfiguration = AlertConfiguration(title: "Delivery Update ", body: "Delivery Update State to (state.prograssState.rawValue)", sound: .default)await current.update(using: state, alertConfiguration: alertConfiguration)}}
关闭Activity状态endPreActivity（）
//建议关闭应用的时候要关闭 不然下次启动就脱离控制了static public func endPreActivity() {let activities = Activity<HeartNoteLiveActivitsLiveAttributes>.activities.filter { act inreturn act.activityState == .active}guard activities.count > 0 else { return }for item in activities {Task {
// print("end activity (item.id)")await item.end(dismissalPolicy:.immediate)}}}
