运行仪器时模拟内存警告？
有办法做到这一点吗？如果是这样，如何以及可以在模拟器和/或真实设备中运行应用程序时完成吗？
是否有其他方法可以测试仪器中内存警告的响应？
Is there a way to do this? If so, how, and can it be done while running an app in the simulator and/or the real device?
Is there an alternative way to test response to memory warnings in Instruments?

据我所知，在设备上，出现内存警告的唯一方法实际上是创建内存不足的情况。您可以通过分配一大块内存并在几秒钟后释放它来做到这一点（无论如何不要忘记释放它）。
这可能看起来像黑客，但却是产生低内存条件的最可靠方法。
关于模拟器，您可能知道，在模拟器中运行应用程序时使用 Instruments 检查内存/性能问题并不完全可靠。无论如何，如果您想这样做，可以尝试发送此通知：

还请记住，模拟器具有“硬件/模拟内存警告”命令。
On the device, as far as I know, the only way to have a memory warning is actually creating a low memory condition. You can do that by allocating a big chunk of memory and freeing it after a few seconds (don't forget to release it, anyway).
This may appear like a hack, but is the most reliable way of producing a low memory condition.
About the simulator, as you possibly know, using Instruments to check for memory/performance issues while running your app within the simulator is not entirely reliable. Anyway, if you would like to do that, you can try sending this notification:

Remember also that the simulator has got the "Hardware/Simulate Memory Warning" command.
您可以在运行 iPhone 模拟器时模拟内存警告，方法是转至菜单并选择：硬件 > 内存警告。模拟内存警告，即使在运行 Instruments 期间也可以随时完成。
You can simulate a memory warning while running the iPhone Simulator by going to the menu and selecting : Hardware > Simulate Memory Warning, which can be done at anytime even during running Instruments .
