cocos2d 屏幕默认是横屏，修改为竖屏的方法

本文主要是介绍cocos2d 屏幕默认是横屏，修改为竖屏的方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

在RootViewController.m文件里面，修改如下代码

的方法shouldAutorotateToInterfaceOrientation

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {//// There are 2 ways to support auto-rotation://  - The OpenGL / cocos2d way//     - Faster, but doesn't rotate the UIKit objects//  - The ViewController way//    - A bit slower, but the UiKit objects are placed in the right place//#if GAME_AUTOROTATION==kGameAutorotationNone//// EAGLView won't be autorotated.// Since this method should return YES in at least 1 orientation, // we return YES only in the Portrait orientation//return ( interfaceOrientation == UIInterfaceOrientationPortrait );#elif GAME_AUTOROTATION==kGameAutorotationCCDirector//// EAGLView will be rotated by cocos2d//// Sample: Autorotate only in landscape mode//if( interfaceOrientation == UIInterfaceOrientationLandscapeLeft ) {[[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeRight];} else if( interfaceOrientation == UIInterfaceOrientationLandscapeRight) {[[CCDirector sharedDirector] setDeviceOrientation: kCCDeviceOrientationLandscapeLeft];}// Since this method should return YES in at least 1 orientation, // we return YES only in the Portrait orientationreturn ( interfaceOrientation == UIInterfaceOrientationPortrait );#elif GAME_AUTOROTATION == kGameAutorotationUIViewController//// EAGLView will be rotated by the UIViewController//// Sample: Autorotate only in landscpe mode//// return YES for the supported orientations// 横屏//return ( UIInterfaceOrientationIsLandscape( interfaceOrientation ) );return ( UIInterfaceOrientationIsPortrait( interfaceOrientation ) );//坚屏#else
#error Unknown value in GAME_AUTOROTATION#endif // GAME_AUTOROTATION// Shold not happenreturn NO;
}

// There are 2 ways to support auto-rotation:

// - The OpenGL / cocos2d way

// - Faster, but doesn't rotate the UIKit objects

// - The ViewController way

// - A bit slower, but the UiKit objects are placed in the right place

#if GAME_AUTOROTATION==kGameAutorotationNone

// EAGLView won't be autorotated.

// Since this method should return YES in at least 1 orientation,

// we return YES only in the Portrait orientation

return ( interfaceOrientation == UIInterfaceOrientationPortrait );

#elif GAME_AUTOROTATION==kGameAutorotationCCDirector

// EAGLView will be rotated by cocos2d
