我正在适配iPhone Duo设备，我想简单适配，即当屏幕展开时，只简单的拉伸我的控件。屏幕折叠状态下，控件压缩。
Orientation我支持Portrait方向。
这样适配是否可以通过苹果AppStore的审核？
iPhone Duo适配疑问，展开状态是否可以只支持横屏
Auto Layout 是个好起点，但只把所有控件拉宽通常不够。展开后先检查文字、按钮和图片有没有被拉得太宽，折叠或半折叠时有没有挤在一起或被中间的折痕区域影响。可以根据当前的可用宽度和 size class 调整布局：外屏用紧凑布局，内屏空间足够时再展示更宽的内容。建议在 iPhone Duo 模拟器里测试合上、展开和半折叠几种状态。只支持竖屏本身不代表一定不能通过审核，关键是每种状态下内容仍然完整、可用。Apple 的设计指南也建议让布局随设备姿态变化，而不是只依赖固定尺寸：https://developer.apple.com/design/human-interface-guidelines/designing-for-iphone-duo
@heroMan Thanks for the question, please think about the iPhone Duo experience to the user instead of passing App Review. I would suggest to go over the resources https://developer.apple.com/iphone-duo/ and take the time to go over each step to make sure works well on all iPhones.
You should use Size Classes to detect when the device transitions from a compact width (folded) to a regular width (unfolded) and adjust the layout accordingly.
