改动如下：

if CONFIG_SCREEN_AUTOSCALE and CONFIG_SCREEN_AUTOSCALE ~="NONE" then
    if type(CONFIG_SCREEN_AUTOSCALE_CALLBACK) == "function" then
        scaleX, scaleY = CONFIG_SCREEN_AUTOSCALE_CALLBACK(w, h, device.model)
    end

-    if CONFIG_SCREEN_AUTOSCALE == "FILL_ALL" then
+    if CONFIG_SCREEN_AUTOSCALE == "EXACT_FIT" then
+        scale = 1.0
+        glview:setDesignResolutionSize(CONFIG_SCREEN_WIDTH, CONFIG_SCREEN_HEIGHT, cc.ResolutionPolicy.EXACT_FIT)
+    elseif CONFIG_SCREEN_AUTOSCALE == "FILL_ALL" then
        CONFIG_SCREEN_WIDTH = w
        CONFIG_SCREEN_HEIGHT = h
        scale = 1.0
        if cc.bPlugin_ then
            glview:setDesignResolutionSize(CONFIG_SCREEN_WIDTH, CONFIG_SCREEN_HEIGHT, cc.ResolutionPolicy.NO_BORDER)
        else
-            glview:setDesignResolutionSize(CONFIG_SCREEN_WIDTH, CONFIG_SCREEN_HEIGHT, cc.ResolutionPolicy.FILL_ALL)
+            glview:setDesignResolutionSize(CONFIG_SCREEN_WIDTH, CONFIG_SCREEN_HEIGHT, cc.ResolutionPolicy.SHOW_ALL)
            end
