Я построил игру Ipad с несколькими контроллерами представлений, в начале которых (при ROOT VC) он запускает таймер для обратного отсчета с 2 часов. Запуск на XCODE 8.2.1/Swift 3.Обновление таймера UILabel.text вызывает TouchesBegan/TouchesEnded, чтобы сбой - как исправить?
На ViewController далее по линии (6-го или 7-го) у меня есть мини-игра, в которой пользователь перетаскивает и удаляет из 8 доступных UIImageViews в 4 других UIImageViews (вроде как пустые слоты) через TouchesBegan/TouchesMoved/TouchesEnded. (UIImageViews устанавливаются с помощью Interface Builder).
В верхней части экрана есть метка (с UserInteraction = disabled), которая обновляется каждые 1 секунду до текущего времени (на обратном отсчете 2 часа), с помощью таймера, который запускается при загрузке текущего контроллера View (showgametimeTimer в коде ниже).
Проблема заключается в том, что это испортит мини-игру (изображения не могут «блокироваться» в местах назначения, когда пользователь заканчивает перетаскивание пальцем), и этот «сбой» происходит только при запуске таймера, обновляющего метку ,
Если я отключу таймер, все работает отлично и, как ожидалось.
Так что в некоторой степени обновление UILabel.text с таймера каждые 1 секунду вызывает что-то, что влияет на TouchesBegan и/или TouchesEnded.
UILabel.text находится в верхней части экрана, объекты для перемещения находятся внизу. Я попытался установить логическую логику - то есть timer.invalidate в начале touchhesBegan, восстановить таймер в конце TouchesEnded, безрезультатно, проблема остается.
Единственный способ исправить это, отключив таймер для этого View Controller.
Я добавляю код, хотя я думаю, что это не поможет увидеть проблему - мне просто интересно, если кто-то столкнулся с той же проблемой или имеет представление о причине/как исправить? Начинающий программист.
Большое спасибо
Соответствующий код:
var showGameTimeTimer = Timer()
override func viewDidLoad() {
super.viewDidLoad()
showGameTimeTimer = Timer.scheduledTimer(timeInterval: 1, target: self, selector: #selector(showTime), userInfo: nil, repeats: true)
showGameTimeTimer.fire()
}
func showTime(){
TimeLeftLabel.text = gameTimerString // gametimerstring gets updated every second from a timer fired at the Root VC
