旋转代码在 iOS6 中不起作用它在 iOS 5 上完美运行

Question

我有这段代码，它在 iOS 5 上完美运行，但在 iOS 6 上不能运行，请帮助

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

Answer 1

让我们试试这个： 首先在viewDidLoad函数里面使用这个代码：

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

然后，我将创建将接收两行代码通知的函数：

- (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。干杯。

在 iOS6 中，“shouldAutorotateToInterfaceOrientation”方法已被弃用。尝试在 plist 文件中设置方向。
