任何身体都可以帮助我避免崩溃吗？

Answer 1

您很可能会看到这一点，因为您在没有自动释放池的线程上执行代码。所有Apple的API都大量使用自动释放池，因此在整个线程中包装一个很重要。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。如果没有这段代码，在线程生命周期内自动释放的所有对象都将被泄露。

Answer 2

设置NSAutoreleasePool的实例。有关详细信息和示例，请查看NSAutoreleasePool Class Reference。

您可能还想浏览Memory Management Programming Guide，看看为什么设置它以及autorelease实际做了什么很重要。

我还发现这篇文章的讨论很有帮助：How does the NSAutoreleasePool autorelease pool work?

Answer 3

来自Apple文档link：

NSAutoreleasePool类用于支持Cocoa 引用计数的内存管理系统。自动释放池存储池本身发送时发送消息的对象倒掉。

重要说明：如果使用自动参考计数（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块比使用实例更有效 NSAutoreleasePool直接;即使你不这样做，你也可以使用它们使用ARC。
