Swift --棒棒糖5 --Xcode文件目录Bundle中有大量的图片加载时内存暴涨的解决方式

//Xcode Bundle文件中大量的图片： 比如
    var images:[String] = ["LoginHintOverlays1.0-NoButtons-1","LoginHintOverlays1.0-NoButtons-2","LoginHintOverlays1.0-NoButtons-3","LoginHintOverlays1.0-NoButtons-4","LoginHintOverlays1.0-NoButtons-5","LoginHintOverlays1.0-NoButtons-6","OrderEntryHintOverlays1.0-NoButtons-1","OrderEntryHintOverlays1.0-NoButtons-2","OrderEntryHintOverlays1.0-NoButtons-3","TimeCardHintOverlays1.0-NoButtons-1","TimeCardHintOverlays1.0-NoButtons-2","TimeCardHintOverlays1.0-NoButtons-3","TimeCardHintOverlays1.0-NoButtons-4","TimeCardHintOverlays1.0-NoButtons-5","CashierHintOverlays1.0-NoButtons-1","CashierHintOverlays1.0-NoButtons-2","CashierHintOverlays1.0-NoButtons-3","CashierHintOverlays1.0-NoButtons-4","CashierHintOverlays1.0-NoButtons-5","CashierHintOverlays1.0-NoButtons-6","CashierHintOverlays1.0-NoButtons-7","CashierHintOverlays1.0-NoButtons-8","EODHintOverlays1.0-NoButtons-1","EODHintOverlays1.0-NoButtons-2","EODHintOverlays1.0-NoButtons-3","EODHintOverlays1.0-NoButtons-4"]
 
for v in 1..<26 {
    
     //26为图片个数
//循环添加到imageView中
self.imageView.image = UIImage(named:"\(self.images[v])") //靠系统去清理内存

替换成下面方式：

self.imageView.image = UIImage.init(contentsOfFile: Bundle.main.path(forResource: self.images[v], ofType: ".png") ?? "")//缺点是每次都得去读，内存中没有存储，比较费效率

可有效在imageView移除之后释放其占据的大量内存。
