iOS6.0 xcode4.5 设置 横屏

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

[window addSubview: viewController.view];

替换为下面代码:

if ( [[UIDevicecurrentDevice].systemVersionfloatValue] < 6.0)

{ // warning: addSubView doesn't work on iOS6

[window addSubview:viewController.view];

}

else

{ // use this mehod on ios6

[windowsetRootViewController:viewController];

}

在RootViewController 中添加下面两个方法 即可:

- (NSUInteger) supportedInterfaceOrientations{

return UIInterfaceOrientationMaskLandscape;

}

- (BOOL) shouldAutorotate {

return YES;

}
