iOSの画面回転について

Last updated at Posted at 2014-05-01

意外なところでハマったんですけど、iOSの指南書で大体はiOS5.0あたりのものが多いのでしょうか。
画面回転における制御がiOS6.0以降に変わっている事に気づかないのですよ…。
あと、DeviceOrientationで制御してるつもりでも上手くいかなかったり…。
というわけで、以下は前後比較。

iOS6.0より前
//画面回転に関する制御
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation
{
    return YES;    //全方位回転

//    if(interfaceOrientation == UIInterfaceOrientationPortrait){
//        // 通常
//        return YES;
//    }else if(interfaceOrientation == UIInterfaceOrientationLandscapeLeft){
//        // 左に倒した状態
//        return YES;
//    }else if(interfaceOrientation == UIInterfaceOrientationLandscapeRight){
//        // 右に倒した状態
//        return YES;
//    }else if(interfaceOrientation == UIInterfaceOrientationPortraitUpsideDown){
//        // 逆さまの状態
//        return NO;
//    }

}
iOS6.0以降
//回転処理が存在し、可能かどうか
- (BOOL)shouldAutorotate;
{
	return YES;                                           //回転許可
}

//回転する方向の指定
- (NSUInteger)supportedInterfaceOrientations;
{
//全方位回転
    return UIInterfaceOrientationMaskAll;
////Portrait(HomeButtonが下)のみ
//      return UIInterfaceOrientationMaskPortrait;
////LandscapeLeft(HomeButtonが右)のみ
//      return UIInterfaceOrientationMaskLandscapeLeft;
////LandscapeRight(HomeButtonが左)のみ
//      return UIInterfaceOrientationMaskLandscapeRight;
////PortraitUpsideDown(HomeButtonが上)のみ
//      return UIInterfaceOrientationMaskPortraitUpsideDown;
////UpsideDown(HomeButtonが上)以外回転
//  return UIInterfaceOrientationMaskAllButUpsideDown;
////横のみ回転
//      return UIInterfaceOrientationMaskLandscape;
}
