iOS6で変更があり、shouldAutorotateToInterfaceOrientationは使わない仕様変更。
よって、３段階の処理が必要。
１. SummaryのSupported Interface Orientations
Landscape LeftとLandscape Rightを選択（黒くする！）
２. AppDelegate.m
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
// -略-
self.window.rootViewController = _viewCtrl;
// -略-
}
3. ViewController.m
- (BOOL)shouldAutorotate {
returnYES;
}
- (NSUInteger)supportedInterfaceOrientations {
returnUIInterfaceOrientationMaskLandscape;
}
iOS5以前は
- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
return (interfaceOrientation==UIInterfaceOrientationLandscapeRight||
interfaceOrientation==UIInterfaceOrientationLandscapeLeft);
}
