我正在开发一款ios应用。这是我从Vimeo API处理的JSON，我想知道处理这些各种图像的正确方法是什么。我想抓住一个高度为540的那个，但在某些情况下，高度可能是541，或其他。另外如果没有高度为540的图像，我应该默认抓取最后一张图像吗？处理这个问题的正确方法是什么？我是否应该尝试抓住倒数第二个图像（大多数时候是高度为540的图像）并且如果只有一个图像抓住那个图像？从生产的角度来看，这种情况通常如何处理？非常感谢您的帮助！

Answer 1

你的逻辑取决于你。迭代图像列表，找到正好是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的那个（根据您的需要更大或更小）。挑选下一个更大的可能是最好的。通常情况下，将较大的图像设置得比试图显示较大的较小图像要小一些。

处理具有各种尺寸JSON的多个图像
