cocos2d-x What is the best way to use device orientation portrait and landscape

Question

I scanned the forum and also in the test examples with no strict answer to the question how can i support game portrait and landscape device orientation. on iOS first is there any kind of example or source or something i can see and learn thanks !

Answer 1

You can refer this : http://www.cocos2d-x.org/projects/cocos2d-x/wiki/Device_Orientation

For ios : in viewcontroller.m

bool shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {

// for Landscape

return UIInterfaceOrientationIsLandscape( interfaceOrientation );

// for Potrait

return UIInterfaceOrientationIsPotrait( interfaceOrientation );

}

if multiple :

bool shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation 

{

return UIInterfaceOrientationIsPortrait(interfaceOrientation)||UIInterfaceOrientationIsLandscape(interfaceOrientation) ;

}

Scaling Contents according to your Orientations :

void didRotateFromInterfaceOrientation:(UIInterfaceOrientation)fromInterfaceOrientation

CGSize s;
if (UIInterfaceOrientationIsLandscape(UIApplication.sharedApplication.statusBarOrientation))
{
s = CGSizeMake(std::max<float>(UIScreen.mainScreen.bounds.size.width,    UIScreen.mainScreen.bounds.size.height), 
                         std::min<float>(UIScreen.mainScreen.bounds.size.width,  UIScreen.mainScreen.bounds.size.height));
} 
else
{
s = CGSizeMake(std::min<float>(UIScreen.mainScreen.bounds.size.width,     UIScreen.mainScreen.bounds.size.height),  
                         std::max<float>(UIScreen.mainScreen.bounds.size.width, UIScreen.mainScreen.bounds.size.height));
}

CCDirector* director = cocos2d::CCDirector::sharedDirector();
director->enableRetinaDisplay(false);
director->getOpenGLView()->setFrameSize(s.width, s.height);
director->getOpenGLView()->setDesignResolutionSize(s.width, s.height, kResolutionShowAll);
director->enableRetinaDisplay(true);
