Cocos 2dx Portrait Mode Object Locations are messed up

Question

I tried making a game in cocos 2dx. It is working perfectly fine in landscape mode. I even checked it on various devices. But when I switch to portrait mode the sprites and nodes in every scene are in different positions and some aren't even visible. I am setting everything relative to the screen width and height. For example:

 backgroundSprite->setPosition(Point(visibleSize.width/2 +origin.x , visibleSize.height/2 +origin.y));

Plus to change to portrait mode, on Xcode, I clicked on the project name, went to the general tab and changed from Landscape Left and Landscape right to Portrait. When I tried to change to portrait mode in the method in the cocos.org page basically editing RootViewController.mm by replacing

return UIInterfaceOrientationMaskAllButUpsideDown;

with

return UIInterfaceOrientationMaskPortrait;

the Xcode simulator still crashed and gave me this error

Answer 1

I have an application in portrait mode.

1) in general settings you need to uncheck landscape and leave portrait only.

2) in info.plist "Supported interface orientations" you have to have Portrait (bottom home button).

3) in AppController.mm in supportedInterfaceOrientationsForWindow return just UIInterfaceOrientationMaskPortrait.

4) also in AppDelegate.cpp in applicationDidFinishLaunching: remember to use setDesignResolutionSize with portrait dimensions, for example 960x640.
