推荐答案

如果您的应用收到内存警告(例如在视图控制器的 didReceiveMemoryWarning 方法中)，您需要释放任何非关键数据.例如，您使用的任何缓存或可以重新生成的内容都应该被转储.

If your app gets a memory warning (such as in your view controller's didReceiveMemoryWarning method) you need to release any non-critical data. Anything that you're using that cached, for example, or that can be regenerated, should be dumped.

例如，如果您的应用程序处理一些数字并将结果存储在一个大数组中，如果您没有主动使用该数组，则应该释放它.然后，当你再次需要它时重新生成它.

For example, if your app crunches some numbers and stores the result in a big array, if you're not actively using that array, you should release it. Then, regenerate it when you need it again.
