升级xcode4.5 iOS 6.0后以前的横屏项目 变为了竖屏,以下为解决办法:
在AppDelegate 的初始化方法
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions中
将
[window addSubview: viewController.view];
替换为下面代码:
if ( [[UIDevice currentDevice].systemVersion floatValue] < 6.0){ // warning: addSubView doesn't work on iOS6 [window addSubview: viewController.view]; }else { // use this mehod on ios6 [window setRootViewController:viewController]; }
在RootViewController 中添加下面两个方法 即可:
- (NSUInteger) supportedInterfaceOrientations{ return UIInterfaceOrientationMaskLandscape; } - (BOOL) shouldAutorotate { return YES;
