2. The height and width of the equipment have not been determined in AutoLayout

You can use Layoutsubviews, but this method is called multiple times, so this method can only be used to control the frame

3. SizeToFit

This method is to let UIView determine the size according to the child view

Commonly used with Uilabel, according to the text to determine the size of the Uilabel
