ios6和ios7禁止屏幕旋轉

- (BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation

{

    return (toInterfaceOrientation == UIInterfaceOrientationPortrait);

}

- (BOOL)shouldAutorotate

{

    return NO;

}

- (NSUInteger)supportedInterfaceOrientations

{

    return UIInterfaceOrientationMaskPortrait;//只支持這一個方向(正常的方向)

}這些方法不行 

再。。。。。

在appdelegate中添加以下代碼

- (NSUInteger)application:(UIApplication *)application supportedInterfaceOrientationsForWindow:(UIWindow *)window{

    if (UI_USER_INTERFACE_IDIOM() == UIUserInterfaceIdiomPad)

        return UIInterfaceOrientationMaskAll;

    else  /* iphone */

        return UIInterfaceOrientationMaskPortrait ;

}
