[UIView setShowsFPS:]: unrecognized selector sent to instance XXX

今天在做sprite Kit game时遇到一个问题。

新建一个项目运行时发现就加了这几句代码无法运行。后来一查原来是storyboard uiview要改一下。改成SKview

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

 SKView *spriteView = (SKView*)self.view;
    
    spriteView.showsFPS = YES;
    spriteView.showsDrawCount = YES;
    spriteView.showsNodeCount = YES;

选择storyboard 然后找到右边 Sustom Slass 把Class 改成SKView
