iPad View控制器内存管理 [英] iPad View Controller Memory Management

问题描述

我的iPad应用程序中有3个视图控制器。当第一个出现时，Instruments中的Activity Monitor告诉我该应用程序的内存为25MB。在[self presentModalViewController]调用之后，弹出一个新的视图控制器，内存增加到50MB，然后是第三个，70-75MB。

I have 3 view controllers in my iPad app. When the first one shown up, the Activity Monitor in Instruments told me that the app's memory was 25MB. After a [self presentModalViewController] call, a new view controller popped up, the memory gone up to 50MB, and then the third one, 70-75MB.

什么是iPad开发的最佳视图控制器内存管理？当我在真正的iPad上时，我总是会收到内存警告。

What is the best view controller memory management for the iPad development? I always receive Memory Warning now when I'm on a real iPad.

提前致谢。我很抱歉我的英语，因为它不是我的母语。 ：）

Thanks in advance. I'm sorry for my English, since it's not my native language. :)

你检查过内存泄漏了吗？

另一个考虑因素是正确分配和释放所有对象，这并不容易，但是必要。

Have you checked your memory leaks?
Instruments -> Leaks.

Another consideration is to alloc and release all object correctly, that is not easy, but necessary.

您可以从构建选项中启用另一个控件： RUN_CLANG_STATIC_ANALYZER 在编译时显示所有错误的版本。

You can enable another control from build options: RUN_CLANG_STATIC_ANALYZER to show all wrong release at compile time.
