共享委托上的内存泄漏
我正在使用共享委托来获取有关 URL 连接的数据。我的代码出现内存泄漏。有人可以告诉我我做错了什么吗？
分析仪警告：
/Users/sathish/Documents/XXX 20100908 ManageMem/Classes/Data Download/XXX DataConnect.m:68:22：警告：第 68 行分配的对象存在潜在泄漏 gXXXDataConnect = [[XXXDataConnect alloc] customInit] ;
XXXDataConnect.h
- (XXXDataConnect*)sharedXXXDataConnect;
XXXDataConnect.m
- (XXXDataConnect *)sharedXXXDataConnect { if(gXXXDataConnect == nil) gXXXDataConnect = [[XXXDataConnect alloc] customInit] ; 返回 gXXXDataConnect ； }
I am using shared delegate for getting data on URL connection. I'm getting a memory leak on my code. Can anybody please tell me what I have done wrong?

好吧，您永远不会释放刚刚分配的 XXXDataConnect。如果你不取消分配，谁会取消分配？
假设这是 Objective-C，我认为您需要一个
return [gXXXDataConnect autorelease]作为函数结束。 http://www.otierney.net/objective-c.html#retain 这里可能是一个有用的链接。Well, you're never deallocating your XXXDataConnect you've just allocated. If you don't deallocate it, who will?
Assuming this is Objective-C, I think you need a
return [gXXXDataConnect autorelease]as your end-of-function. http://www.otierney.net/objective-c.html#retain might be a helpful link here.
