更新:苹果公司推出了一个新的媒体管理器，它只需要你为最大的iPhone和/或iPad设备创建艺术品。将为您创建较小的图像。请注意，如果您以前没有创建iPad Pro图像，那么现在必须创建(如果您支持iPad)。

更新:现在支持新设备的截图和应用程序预览。

通过各自设备的模拟器，我们可以方便地使用cmd+S命令进行截图。这为我们模拟的设备提供了精确的分辨率。审查小组本应提及这一点，但从未提及。：）

这个答案是更新的Xcode 13。

App Store Connect目前要求以下类别的图像:

iPhone 6.7”显示屏

这是1290 x 2796像素。您可以使用以下模拟器来创建这些截图:

iPhone 14 Pro Max

iPhone 6.5”显示屏

这是1242 x 2688像素。您可以使用以下模拟器来创建这些截图:

iPhone 13 Pro Max iPhone 12 Pro Max iPhone 11 Pro Max iPhone XS Max iPhone XR

iPhone 5.5”显示屏

这是1242 x 2208像素。您可以使用以下模拟器来创建这些截图:

iPhone 8 Plus iPhone 7 Plus iPhone 6s Plus

iPad Pro(第三代)12.9英寸显示屏

这是2048 x 2732像素。您可以使用iPad Pro(12.9英寸)(第五代)模拟器创建此大小的图像。

iPad Pro(第二代)12.9英寸显示屏

这是2048 x 2732像素。这是与iPad Pro(12.9英寸)(第五代)完全相同的尺寸，所以大多数人可以在这里使用相同的截图。但是看看这个。

笔记

Data source: Official Screenshot specifications page on the Apple site. Thanks to this answer for the link. Not all of the devices listed above produce the exact pixel dimensions listed, but Apple seems to accept the proportions. Use File > New Screen Shot (Command+S) in the simulator to save a screenshot to the desktop. On a real device press Sleep/Wake+Home on the iPhone/iPad (images available in Photo app) The pixel dimensions above are the full screen portrait orientation sizes. You shouldn't include the status bar, so you can either paste background color over the status bar text and icons or crop them out and scale the image back up.
