iOS 10.1.1 弹出窗口说 "Application May Slow Down Your iPhone"

Question

当我在我的真实设备上通过 Xcode 构建和运行我的应用程序时，我收到一个弹出窗口:

AppName May Slow Down Your iPhone

The developer of this app needs to update it to improve its compatibility.

我没有看到任何内存问题，而且我的应用程序崩溃也从未遇到过任何问题。

那么是什么导致了这个可怕的信息？

这不是内存或崩溃问题 - 这是 Apple 要求开发人员更新他们的 apps with only 32-bit support with 64-bit support .

您必须使用现有应用构建 64 位二进制文​​件。为此:

Start by building the app for the 64-bit runtime, fixing any warnings that occur as well as searching your code for specific 64-bit issues. For example:

• Make sure all function calls have a proper prototype.
• Avoid truncating 64-bit values by accidentally assigning them to a 32-bit data type.
• Ensure that calculations are performed correctly in the 64-bit version of your app.
• Create data structures whose layouts are identical in the 32-bit and 64-bit versions of your app (such as when you write a data file to iCloud).
