为什么SimpleEKDemo代码中存在内存泄漏？
分析 SimpleEKDemo 应用程序时来自 Apple 我注意到存在一些内存泄漏。
其中一个泄漏是 __NSArrayM，它在泄漏块历史记录中有 3 行：Malloc/Assign/Release。
问题 - 有人可以指出这里问题的根本原因吗？ （我正在尝试学习如何获取创建泄漏对象的 Instruments 输出，然后从那里找出根本原因，所以这非常有用）
When profiling the SimpleEKDemo application from Apple I note there are some memory leaks.
One of the leaks is __NSArrayM which has 3 lines in the Leaked Blocks history, a Malloc/Assign/Release.
Question - can someone point out the root cause issue here? (I'm trying learn how to take Instruments output of where a leaky object was created, and then from there work out root cause, so this would be really useful)

您会注意到，当您运行存在泄漏的演示时，
viewDidLoad（责任框架）中存在泄漏。如果您切换到Call Tree详细信息并且启用了Invert Call Tree，您将看到与调用+[NSArray new]相关的泄漏>。如果稍微打开它，您将看到在RootViewController的viewDidLoad中调用的initWithArray。问题是，eventsList 是一个保留属性，因此创建的对象的保留计数为 2。但是它仅被释放一次通过
dealloc中的release或通过eventsList的重新分配。您必须自动释放该对象。一旦修复，您就不应该出现任何错误。
You will notice that when you run the demo with leaks that there is a leak in
viewDidLoad(responsible frame). If you switch toCall Treedetail and if you have enabledInvert Call Tree, you will see a leak associated with the call+[NSArray new]. If you open that a bit, you will seeinitWithArraywhich is called in theRootViewController'sviewDidLoad. The problem bit is,eventsListis aretained property so the object created has a retain count of 2. However it is onlyreleased once either through thereleaseindeallocor through reassignment ofeventsList. YOu will have to autorelease this object.Once fixed, you shouldn't get any errors.
