这既不坏也不意外.在没有任何启动图像的情况下，应用程序运行起来就好像这是一个小得多的设备，例如屏幕尺寸为 320 x 480.它比 iPhone X 窄，因此它被放大(缩放)到设备屏幕的宽度(这样我们从顶部和底部，而不是从侧面，作为你的第一个信箱截图显示).

That's neither bad nor unexpected. Without any launch image, the app runs as if this were a much smaller device, e.g. with a screen size of 320 x 480. That is narrower than the iPhone X so it is enlarged (zoomed) to the width of the device screen (so that we letterbox from the top and bottom, but not from the sides, as your first screenshot shows).

使用启动图像时，字体和放大消失了，您以 375 x 812 的屏幕尺寸原生运行.现在我们在相同尺寸的屏幕上看到更多的宽度点，因此相同的点尺寸字体看起来更小，就像在更广阔的视野中从更远的地方看到的房子.

With the launch image, that letterboxing and enlargement goes away and you run natively with a screen size of 375 x 812. Now we are seeing more points of width on the same size screen, so the same point size font appears smaller, like a house seen from further away in a wider field of view.

您可以通过使用和不使用启动图像记录 UIScreen.main.bounds 来轻松确认这一点.

You can easily confirm this by logging UIScreen.main.bounds with and without the launch image.
