如何修正iOS6上Oritentation的问题

1.将addSubview修改为setRootViewController

[window addSubview: viewController.view];

修改如下：

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];}

2.修改shouldAutorotateToInterfaceOrientation

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {    return UIInterfaceOrientationIsLandscape( interfaceOrientation );}

iOS6以前会呼叫这方法来判断手机是垂直或打横

// For ios6, use supportedInterfaceOrientations & shouldAutorotate instead of shouldAutorotateToInterfaceOrientation- (NSUInteger) supportedInterfaceOrientations{    return UIInterfaceOrientationMaskLandscape;}- (BOOL) shouldAutorotate {    return YES;}

iOS6需在加上上面方法
