iPhone / iPad App定位

问题描述：

我的应用程序的iPhone版本支持 UIDeviceOrientationPortraitUpsideDown 和 UIDeviceOrientationPortrait ，但iPad版本支持所有方向。

The iPhone version of my app supports UIDeviceOrientationPortraitUpsideDown and UIDeviceOrientationPortrait, but the iPad version supports all Orientations.

在我的视图控制器中我有这个：

In my view controller I have this:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation     {
    return YES;
}

我的Info.plist文件包含：

and my Info.plist file has this:

问题在于，当我将应用程序构建到iPod时，应用程序不会颠倒过来。 iPad将支持所有方向。

The problem is that when I build the app to my iPod, the app won't turn upside down. The iPad will support all Orientations.

我已经尝试一起删除 shouldAutorotateToInterfaceOrientation ，我试过这个代码：

I've tried removing the shouldAutorotateToInterfaceOrientation all together and I've tried this code:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return (interfaceOrientation = UIDeviceOrientationLandscapeLeft) && (interfaceOrientation = UIDeviceOrientationLandscapeRight) && (interfaceOrientation = UIDeviceOrientationPortraitUpsideDown) && (interfaceOrientation = UIDeviceOrientationPortrait);
}

但由于某种原因，颠倒只是行不通！还有其他解决方案吗？

But for some reason, the upside down just won't work! Are there any other solutions for this?

编辑：使用Xcode 4.5 iOS6

答

想出来，iOS6 SDK使用 shouldAutorotate 所以这是我的新代码：

Figured it out, the iOS6 SDK uses shouldAutorotate so here is my new code:

-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)interfaceOrientation {
    return YES;
}

-(BOOL)shouldAutorotate {
     return YES;
}

-(NSUInteger)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskAll;
}
