iOS以编程方式获取物理屏幕大小？ [英] iOS get physical screen size programmatically?

问题描述

这可能吗？我想要的是英寸数，而不是像素数。我知道它大概是160 ppi。但不完全是。

Is this possible? I want the number of inches, not the number of pixels. I know it is approximately 160 ppi. But not exactly.

推荐答案

如果它可用，它将在 UIScreen 或 UIDevice 但它不存在。

If it were available it would be in UIScreen or UIDevice but it is not there.

您可以在 Erica的UIDevice-中从信息中推断出来 - 扩展名和维基百科上列出的每个设备的规格。

You can infer it from info in Erica's UIDevice-extension and the specs for each device listed here on Wikipedia.
