swift3 - My Image stop animation when I do a request in swift 3 -


i've got uimage, needs rotate until call server ends. image rotates 1 time , stops after that.

my code:

    @iboutlet var imgloader: uiimageview!     override func viewdidload() {     super.viewdidload()     dispatchqueue.global(qos: .userinitiated).async {         self.getsalons()     }     self.launchloaderdesign()     notificationcenter.default.addobserver(forname:nsnotification.name("loadallshownotification"), object: nil, queue: nil, using: notificationfinish) }  func getsalons() -> void {     let api:apisvain = apisvain()     api.getheartstrokesalon()     api.getsalonforhomepage() }  func launchloaderdesign() -> void {     var posimg:int = 0     uiview.animate(withduration: 0.5, delay: 0, options: .curveeasein, animations: { () -> void in             self.imgloader.transform = self.imgloader.transform.rotated(by: cgfloat(m_pi_2))     })     { (finished) -> void in         self.launchloaderdesign()     } } func getsalonforhomepage(){     let url = "my_url"     alamofire.request(url, method: .get).validate().responsejson     { response in         if (response.error == nil)         {             let json = json(response.result.value!)              (index, element) in json             {                 let show:show = show(json: element, index: index)                 staticdata.arrayofshow.append(show)             }             notificationcenter.default.post(name:nsnotification.name("loadallshownotification"), object: nil, userinfo: nil)         }         else         {             print(response.error!)         }     } }

my function getsalonforhomepage sends notification, , when catch use performsegue move new page.

i think problem came misunderstanding of multi-threading.

ps: using alamofire 4, send request server.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now...
