Answer 1

The white space you see is the controller default view background color.

The problem is when you try to add a top/bottom constraint to any view. It adds the constraint to the Layout Guide (default behavior).

To over-write that. you can click the arrow next to the constrait constant value. which shows the views that you can connect against. obviously you need to connect with the one with the largest distance value, and set the constant value to 0.

Same applies to the launch screen controller.

If you have the constraint already added. you can change that from the constraint Attributes Inspector:

If you have a top constraint you need to choose the First Baseline. and if you have a bottom constraint you need to choose Last Baseline

这刚刚解决了我的问题！尝试选择 SuperView 选项，如屏幕截图所示。我在屏幕顶部也遇到了同样的问题，我做了同样的程序，并且成功了！
