旋转代码在iOS6中不起作用，它在iOS 5上完美运行

Question

我有这个代码，它在iOS 5上完美运行，但在iOS 6上没有帮助

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)orientation
    {
        return (orientation != UIDeviceOrientationPortrait) &&
        (orientation != UIDeviceOrientationPortraitUpsideDown);
    }

Answer 1

试试这个： 首先在viewDidLoad函数内部使用以下代码：

- (void)viewDidLoad
{
    [super viewDidLoad];
    [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(orientationChanged:) name:@"UIDeviceOrientationDidChangeNotification" object:nil];
}

然后，我创建的函数将接收两行代码的通知：

- (void)orientationChanged:(NSNotification *)object{
    NSLog(@"orientation change");
    UIDeviceOrientation deviceOrientation = [[object object] orientation];
    if(deviceOrientation == UIInterfaceOrientationPortrait || deviceOrientation == UIInterfaceOrientationPortraitUpsideDown){
        if(deviceOrientation ==UIInterfaceOrientationPortrait){
            NSLog(@"Changed Orientation To Portrait");
            // Handle your view.
        }
    }else{
        if(deviceOrientation ==UIInterfaceOrientationLandscapeLeft){
            NSLog(@"Changed Orientation To Landscape left");
            // Handle your view.
        }else{
            NSLog(@"Changed Orientation To Landscape right");
            // Handle your view.
        }

    }
}

我希望我的回答会有所帮助。欢呼声。

在iOS6中，不推荐使用“shouldAutorotateToInterfaceOrientation”方法。尝试在plist文件中设置方向。
