The original iPhone screen has a resolution of 163dpi- use that in your template if you want to be able to print your screen designs at actual size.
原始 iPhone 屏幕的分辨率为 163dpi- 如果您希望能够以实际尺寸打印屏幕设计，请在模板中使用该分辨率。

72 is the dpi for images
72 是图像的 dpi

Given the difference in the dpi between the iPhone and the simulator, you might want to use the raw pixel values of 480x320 for the iPhone screen.
鉴于 iPhone 和模拟器之间 dpi 的差异，您可能希望对 iPhone 屏幕使用 480x320 的原始像素值。

The iPhone screen has 163 DPI, but I've found that images at that resolution appear too small in Xcode and Interface Builder. I recommend pretending that the screen has 72 DPI when making bitmap images for the iPhone, but remember that the screen has 163 DPI if you're drawing a ruler.
iPhone 屏幕具有 163 DPI，但我发现该分辨率的图像在 Xcode 和 Interface Builder 中显得太小。我建议在为 iPhone 制作位图图像时假设屏幕具有 72 DPI，但请记住，如果您正在绘制标尺，屏幕具有 163 DPI。
