之前播放動(dòng)畫用imageView自帶的組動(dòng)畫,發(fā)現(xiàn)在4s上會(huì)因?yàn)閮?nèi)存警告crash,就替換成每間隔0.1s替換imageView的image
func showImages(times: Int) {
guard times < 42 else {
self.dismiss()
return
}
if let filePath = Bundle.main.path(forResource: "tickets-\(times).png", ofType: nil),
let ticketsImage = UIImage(contentsOfFile: filePath) {
self.animationView.image = ticketsImage
}
DispatchQueue.main.asyncAfter(deadline: DispatchTime.now() + 0.1, execute: {
self.showImages(times: times + 1)
})
}
func dismiss() {
UIView.animate(withDuration: 0.2, animations: {
self.animationView.alpha = 0.0
}) { (_) in
self.animationView.removeFromSuperview()
}
}
