问题描述

我注意到使用不同的应用程序，即使您从 xcode 中删除 iPad 兼容性(见下图)

I have noticed using different applications that, even when you remove the iPad compatibility from xcode (see picture below)

该应用仍会在 iTunes 应用页面中显示与 iPad 兼容(见下图):

the app will still show that is compatible with iPad in the iTunes app page (see picture below):

因此，我想知道，Whatsapp 是如何从其应用中删除 iPad 兼容性的?(见下图):

Therefore, I am wondering, how did Whatsapp removed the iPad compatibility from it's app? (see image below):

谢谢

推荐答案

因为 WhatsApp 在没有电话的情况下无法工作(该应用需要电话号码)，所以他们确实使用了 telephony 作为 UIRequiredDeviceCapabilities 在他们的信息列表中的值.这会将应用程序限制为指定为电话的设备.目前仅适用于 iPhone，因此该应用程序无法在 iPad 和 iPod 上运行.

Because WhatsApp does not work without telephony (the app requires the phone number) they did use telephony as UIRequiredDeviceCapabilities value in their info-plist. This limits the app to devices that are designated as telephones. Which currently covers only iPhones, so the app won't work on iPads and iPods.

通常你不能这样做，Apple 不允许任意设置UIRequiredDeviceCapabilities.如果您的应用程序确实需要电话支持，您当然可以使用密钥.

Generally you can't do that, Apple does not allow to arbitrary set UIRequiredDeviceCapabilities. If your app really requires telephony support you can of course use the key.
