任何机构都可以帮助我避免崩溃吗？

您很可能会看到这种情况，因为您在没有自动释放池的线程上执行代码。Apple 的所有 API 都大量使用自动释放池，因此在整个线程中封装一个非常重要。这方面的一个例子如下：

- (void)myThreadMethod:(id)anObject {
    NSAutoreleasePool * pool = [[NSAutoreleasePool alloc] init];
    NSLog(@"This is some objective-c code...");
    [pool drain];
}

[池排水]部分非常重要。如果没有那段代码，在线程生命周期内自动释放的所有对象都将被泄露。

设置NSAutoreleasePool. 查看NSAutoreleasePool 类参考以获取详细信息和示例。

您可能还想浏览一下内存管理编程指南，了解为什么设置它很重要以及autorelease实际做了什么。

我还发现这篇文章的讨论很有帮助：NSAutoreleasePool 自动释放池是如何工作的？

从 Apple 文档链接：

NSAutoreleasePool 类用于支持 Cocoa 的引用计数内存管理系统。自动释放池存储在池本身耗尽时发送释放消息的对象。

重要提示：如果您使用自动引用计数 (ARC)，则不能直接使用自动释放池。相反，您使用 @autoreleasepool 块。例如，代替：

 NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; 
// Code benefitting from a local autorelease pool. 
[pool release];

你会写：

 @autoreleasepool {
     // Code benefitting from a local autorelease pool. 
}

@autoreleasepool 块比直接使用 NSAutoreleasePool 的实例更有效；即使您不使用 ARC，也可以使用它们。
