iPhone内存警告级别= 2 [英] iPhone Memory warning level=2

问题描述

我有一个应用程序，可以在彼此之间叠加大量视图.

I have an app that stacks quite a nice amount of views on top of each other.

有时我会收到内存警告"级别2(这是预料之中的).

At some point I receive a Memory warning level2 (which is kind of expected).

问题是，当我运行Instruments时，我没有任何内存泄漏，并且该应用占用了大约9-10MB的内存...这不是那么，我会说?

The thing is, when I run Instruments, I don't have any memory leaks and the app takes up something like 9-10MBs... which is not that much, I'd say?

问题是:一个应用可以消耗多少内存，也就是iPhone有多少RAM?

Question is: how much memory can an app consume, a.k.a. how much RAM does the iPhone have?

我知道我可以响应接收到的MemoryWarning并释放一些内存-但这意味着我必须摆脱一些视图，这不是我正在寻找的解决方案...

I know that I can respond the the receivedMemoryWarning and free up some memory - but this would mean that I'd have to get rid of some of the views, which is not the solution I'm looking for...

该应用到目前为止还没有崩溃-但我担心它可能会在其他用户的iPhone上崩溃...

The app didn't crash so far - but I'm concerned that it might crash on other user's iPhones...

推荐答案

应用程序可以使用30-40 MB的实际内存或更大的内存，这将不会有问题.当您收到内存警告级别1之前，直到那时都没有问题，但是如果您收到内存警告级别2，则该应用程序可能会或将在一段时间后崩溃.

An application can use 30-40 MB of real memory or greater then this and there will not be a problem. When you are getting a memory warning level-1, till then there is not a problem, but if you get memory warning level-2, then the app might or will crash after some time.

解决方案是，当您收到2级内存警告时，在您的委托方法内部，释放一些您当前未使用的内存.

solution is, when you get memory warning level-2, inside your delegate method, release some memory which you are not using currently.
