ios - Parse.enableLocalDatastore() - 警告 : A long-running operation is being executed on the main thread

Question

此外，我还在 dispatch_async 中执行了 Parse.enableLocalDatastore() - 我仍然收到警告。

即使我在 warnParseOperationOnMainThread 上添加一个符号断点，它也不会中断

这是应用委托(delegate)的代码片段

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

        dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0)) {
            Parse.enableLocalDatastore()

            Parse.setApplicationId("XXX", clientKey: "YYY")
            PFAnalytics.trackAppOpenedWithLaunchOptionsInBackground(launchOptions, block: nil )

            var defaultACL = PFACL()
            defaultACL.setPublicReadAccess(true)
            defaultACL.setPublicWriteAccess(false)
            PFACL.setDefaultACL(defaultACL, withAccessForCurrentUser:true)

            CAUser.registerSubclass()

            NSLog("App finish loading")

            dispatch_async(dispatch_get_main_queue()){
                () -> Void in
                // any UI updates need to happen in here back on the main thread
            }
        }

        return true
    }  

请求

感谢有人向我强调，缺少什么以避免出现此警告消息？

这是一个错误，将在下一个 Parse SDK 版本中修复 https://developers.facebook.com/bugs/1537241009878763/
