这条代码可能指的是没有Home键的其他IOS设备，比如苹果电视机顶盒。但是公开的其他代码、代码内的图片以及多年来的谣言都能与这种说法对上号。

Pictures found in the code that appear to depict the new phone, for instance, show the design including some of the "forehead" that sits at the top, but none of the "chin" at the bottom that houses the button. As such, there appears to be no space for a physical home button and it will presumably be depicted on screen instead, as it is on Android.

比如，图片代码中的一些描述似乎显示了iPhone8的设计，手机的顶部还留有“前额”，但是底部Home键所在的“下巴”却没有了。因此，似乎已经没有容纳Home键的物理空间，它可能像安卓系统那样，出现在屏幕上。

Some had hoped that the long-rumoured removal of the home button would actually mean that it was hidden under the bottom of the screen, and that the fingerprint sensor would shine through the display. But there appears to be no such reference to a TouchID fingerprint sensor, and so it's likely that the button will be entirely virtual.

一些人曾期望这则流传已久的谣言实际上意味着将Home键隐藏在屏幕底下，而指纹传感器会透过显示屏工作。但是TouchID指纹传感器似乎并未被提及，因此Home键可能将彻底变为虚拟的。

That will also mean that the button can move out of the way when it is not required, such as when people are watching videos.
