如何在ipad mini上检测到dpi？ [英] How can I detect the dpi on an ipad mini?

问题描述

我有一个ipad应用程序，带有一些非常小的触摸点，在普通ipad的10英寸屏幕上几乎无法接受。我希望能够获得设备dpi，这样我就可以扩大mini的小元素的大小以及将来发布的任何mini。

I've got an ipad app with some pretty small touch points that are just barely acceptable on the 10 inch screen of a normal ipad. I'd like to be able to get the device dpi so I can scale up the size of the small elements for the mini and whatever future mini's that are released.

推荐答案

DPI是每英寸163像素（ppi）：
