[UIView setShowsFPS:]: unrecognized selector sent to instanc

Today, I encountered a problem in sprite Kit game.

When creating a new project, you will find that these code statements cannot be run. It turns out that the storyboard uiview needs to be changed. Change to SKview

In your storyboard, did you set the 'customclass' of the VC's root view to SKView?

SKView * spriteView = (SKView *) self. view;

SpriteView. showsFPS = YES;
SpriteView. showsDrawCount = YES;
SpriteView. showsNodeCount = YES;
Select storyboard and find Sustom Slass on the right to change the Class to SKView.
