iPhone 12 max pro 2778.000000 1284.000000

why i am getting different value like these

You are getting correct resolutions in cocos2dx 3.17.2. This is because cocos2dx 3.16 is using bunch of start screens in png for every iPhone model it knows, and of course, 11&12 max pro is not among them. The more universal technique, recommended by Apple, is use LaunchScreen.storyboard instead of launch images, to activate “native” resolution any (and even not yet invented) iphones. Cocos2dx 3.17.2 and v4. is using LaunchScreen.storyboard.
