我正在开发一个 iOS 应用程序。 这是我从 Vimeo API 使用的 JSON，我想知道处理这些不同图像的正确方法是什么。我想抓取高度为 540 的高度，但在某些情况下，高度可能为 541 或其他。还有如果没有高度为540的图片，我是不是应该默认抓取最后一张图片？处理这个问题的正确方法是什么？我是否应该尝试抓取倒数第二张图片(大多数情况下高度为 540 的图片)，如果只有一张图片，则抓取那一张？从生产的角度来看，这种情况通常是如何处理的？非常感谢您的帮助!
最佳答案
你的逻辑由你决定。遍历图像列表并找到恰好为 540 的图像。如果不存在，则由您决定使用什么。您可以使用最接近 540 的值(根据您的需要选择更大或更小的值)。选择下一个更大的可能是最好的。将较大的图像缩小一点通常比尝试将较小的图像放大显示更好。
