对于任何想要上传图像分辨率的人(如果你想创建一些花哨的photoshop截图)，它们是:

iPhone 6: 750 × 1334 iPhone 6 Plus: 1242 × 2208

这里有很好的参考指南:http://www.paintcodeapp.com/news/iphone-6-screens-demystified(谈论iPhone 6+的分辨率和下采样)。

对于xcode 11.1，不包含iPad pro iPad Pro (2nd Gen) 12.9" Display在终端运行此命令

xrun simctl创建iPad Pro(12.9英寸)(第二代)“com.apple.CoreSimulator.SimDeviceType。iPad-Pro——12-9-inch 2 nd-generation - com.apple.CoreSimulator.SimRuntime.iOS-13-1”

看这里

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。：）

另外，请注意，你可以设置透明度，即使你的图像实际上没有任何透明度。如果你用的是photoshop，选择“保存为网页格式”，取消选择“透明”，或者直接将图片转换成jpg格式。iTunes Connect似乎也拒绝透明度。
