iPhone内存管理，一个新手问题 [英] iPhone memory management, a newbie question

问题描述

我在(Apple)示例代码中看到了两种类型的分配内存的方式，并且不确定我是否了解差异和由此产生的行为.

I've seen in (Apple) sample code two types of ways of allocation memory, and am not sure I understand the difference and resulting behavior.

// FAILS
NSMutableArray *anArray = [NSMutableArray array];
[anArray release];

// WORKS
NSMutableArray *anArray1 = [[NSMutableArray alloc] init];
[anArray release];

失败"是指我收到崩溃/运行时警告等信息，而并非总是在我致电该发行版时就收到...

By "FAILS" I mean I get crashes/runtime warnings etc., and not always as soon as I call the release...

任何解释都值得赞赏.

谢谢

推荐答案

请记住

NSMutableArray *anArray = [NSMutableArray array];

行为类似:

NSMutableArray *anArray1 = [[[NSMutableArray alloc] init] autorelease];

因此，在尝试释放自动释放的对象时，再次执行释放会导致崩溃.

So doing a release again will cause the crash as you are trying to release an autoreleased object.

希望这对您有所帮助.

谢谢
