iPhone 6和6 Plus响应断点 [英] iPhone 6 and 6 Plus Responsive Breakpoints

问题描述

根据苹果网站：

iPhone 6的分辨率为1334x750像素，分辨率为326 ppi，对比度为1400：1（典型值）

The iPhone 6 has 1334-by-750-pixel resolution at 326 ppi with 1400:1 contrast ratio (typical)

iPhone 6+的分辨率为1920 x 1080像素，分辨率为401 ppi，对比度为1300：1（典型值）

The iPhone 6+ has 1920-by-1080-pixel resolution at 401 ppi with 1300:1 contrast ratio (typical)

然而，CSS媒体查询响应的断点是什么？ （纵向和横向）

However, what would the CSS media query responsive breakpoints be for each? (portrait and landscape)

我不完全明白如何使用各种响应模拟器测试视网膜屏幕大小。任何帮助将不胜感激。

I don't fully understand how to test the retina screen sizes using the various responsive emulators out there. Any help would be much appreciated.

推荐答案

您引用的是设备的物理像素，而不是css device-width sizes。根据此 tweet ，两者的设备宽度为：

You're referencing the physical pixels of the device, rather than the css device-width sizes. According to this tweet, the device-widths for the two will be:

iPhone 6: 375px (2.0 DPR)
iPhone 6 Plus: 414px (2.6 DPR)

知道（假设tweet是正确的），并假设你使用正确的 meta viewport 标签，查看大致：

Knowing that (and assuming the tweet is correct), and assuming your using the proper meta viewport tag, you're looking at roughly:

iPhone 6: 375px (portrait), 667px (landscape)
iPhone 6 Plus: 414 (portrait), 736px (landscape)

希望这有助于！

编辑：

关于iPhone 6的 2.6 DPR 此外， 3.0 DPR 实际上缩小了 1.15 ，这导致 2.6 DPR 。有关详情，请访问 http://www.paintcodeapp.com/news/iphone-6-screens-神秘化（感谢@mdcarter的链接！）

Regarding the 2.6 DPR of the iPhone 6 Plus, it's actually 3.0 DPR downsized by 1.15, which results in 2.6 DPR. More info can be found at http://www.paintcodeapp.com/news/iphone-6-screens-demystified for clarification (thanks @mdcarter for the link!)
