[UIView setShowsFPS:]: unrecognized selector sent to instanc

今天在做sprite Kit game時遇到一個問題。

建立一個項目運行時發現就加了這幾句代碼無法運行。後來一查原來是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;
選擇storyboard 然後找到右邊 Sustom Slass 把Class 改成SKView
