iPhone中的cfnetwork内存泄漏

Question

我在我的应用程序 - 仪器检查中遇到了以下类型的内存泄漏.我已正确分配和解除分配每个对象.但是我得到了这种类型的内存泄漏.

std :: _ Deque_base <__ CFURLCacheNode*,std :: allocator <__ CFURLCacheNode*>>> :: _ M_allocate_node()

Answer 1

在appDidFinishL中实现以下代码.功能

不会有泄漏

- (void)applicationDidFinishLaunching:(UIApplication *)application {    

// Override point for customization after app launch    
NSURLCache *sharedCache = [[NSURLCache alloc] initWithMemoryCapacity:0 diskCapacity:0 diskPath:nil];
[NSURLCache setSharedURLCache:sharedCache];
[sharedCache release];

[window addSubview:[navigationController view]];
[window makeKeyAndVisible];

}
