问题
In my cocos2d application, inside the applicationDidFinishLaunching method for my app delegate, I set the orientation via [director setDeviceOrientation:kCCDeviceOrientationPortrait] because I really only want portrait. However, Apple rejected my app saying it must support upside down portrait as well.
I'm not certain how I detect this, though. Reading the currentDevice orientation seems to return an unknown orientation, so my questions are twofold:
1) How am I supposed to detect the orientation so I can properly set it to either portrait or upsidedown portrait (where it will stay for good).
2) I suspect I'll have an issue with the splash screen because it's loaded before I reach this point in the delegate. How can I properly detect the orientation so I can set the right splash screen?
回答1:
I can only edit the codes to fix your first question.. i hope you are using .99.5..
in RootViewController.h, in the function
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
look for this line:
#elif GAME_AUTOROTATION == kGameAutorotationUIViewController
{
return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );
}
change to
return ( UIInterfaceOrientationIsPortrait( interfaceOrientation ) );
