Apple says that this entitlement will inform the system that an app "may perform better by exceeding the default app memory limit." Apple's developer documentation doesn't specify how much extra RAM an app may be exposed to and also says this is limited to "supported devices." 在iPadOS/iOS 15 beta 2中，苹果引进了一个开发者可以要求的权利：让他们的 app可以接触到更多的RAM。苹果说这个权利可以跟系统说，这个app如果有更多 RAM的话可以表现的更好。苹果并没有说多少RAM app可以使用，但仅说这个仅限 於有支援的装置 Add this entitlement to your app to inform the system that some of your app's core features may perform better by exceeding the default app memory limit on supported devices. If you use this entitlement, make sure your app still behaves correctly if additional memory isn't available. 把这个权利加到你的app中，告诉系统你的app有些重要的功能在更多RAM的时候可以 表现的更好，如果你用了这个权利，记得让你的app在没有这些额外的RAM的时候 还可以表现正常 While Apple doesn't specify the amount of extra RAM an app may request, the wording of the documentation, which advises developers to use a function to "determine the amount of memory available," suggests the ceiling of memory apps may request may be relatively high. 虽然苹果没有说一个app可以要求多少额外的RAM，说明文件却建议开发者先利用一个 函数去决定系统还有多少的RAM可以用，表示这个上限还蛮高的 心得： 谢主荣恩，终於有RAM可以用了 但在iPad RAM几乎100%被用完的情况，到底多余可以用的RAM要如何决定呢？ --
