### 启动

- **[KSAppDelegate didFinishLaunchingWithOptions]**

```

//1. launch 初始化，记录启动时间等

[KSLaunchManager sharedManager]finishStageTimer: withLog:@"Finish launchingWithOptions"];

[KSLaunchManager sharedManager] startStageTimer: withLog:@"Start init"];

[KSLaunchManager sharedManager] setIsStartApp]

....

// 2. 自动播放配置

setFeedAutoPlaySet

setFeedPreviewPlaySet

  //NSUserDefaults_FeedPreviewPlaySetting(settingvc)

//3. 数据合并前

runLaunchTaskBeforeDatabaseComplatibleCheck];

  //[KSLaunchManager executeInMain: as:@"disableLandscapeRotation"] ^ {

  //}

  //InitWXApiWrapper

  //setupKSImgProcEnv

  //KSPlugDeviveStatisManagerSetupObserver

  //[KSLaunchManager sharedManager] finishStageTimer: withLog:@"finish runLaunchTaskBeforeDatabaseComplatibleCheck"]

  ...

//4. 初始化主界面

bool [KSCoredataManager sharedInstance] isDataBaseCompatible

if isDataBaseCompatible {

  executeInMain: as:@"setupManagedObjectContexts"];

  //log

  [WnsSdkHelper sharedInstance]

  //展示隐私弹窗，rootvc

  checkAndShowPrivacyGuideIfNeeded

} else {

// 数据迁移vc

[KSDBMigrationNavVC alloc] initWithRootViewController:

setRootViewController:

//数据迁移...
