问题：

将 ipad 端软件设置为横屏显示后，关闭 Modal 弹窗报错。

Modal was presented with 0x2 orientations mask but the application only supports 0x18.Add more interface orientations to your app's Info.plist to fix this.NOTE: This will crash in non-dev mode.

解决：

supportedOrientations={['portrait', 'landscape']}

<Modal supportedOrientations={['portrait', 'landscape']} />

supportedOrientations
用于指定在设备切换横竖屏方向时，modal 会在哪些屏幕朝向下跟随旋转。在 iOS上，除了本属性外，还会受到应用的 Info.plist 文件中UISupportedInterfaceOrientations的限制。如果还设置了presentationStyle属性为pageSheet或formSheet，则在 iOS 上本属性将被忽略。
