我在 RestKit 的错误回调中切换控制器时遇到问题。它会导致错误：

*** -[RKObjectLoader onDidFailWithError]: message sent to deallocated instance 0x1ddd9680

我正在- (void)objectLoader:(RKObjectLoader *)objectLoader didFailWithError:(NSError *)error使用以下代码切换方法：

[[[[RKObjectManager sharedManager] client] requestQueue] cancelAllRequests];

scAppDelegate *appDelegate = (scAppDelegate *)[UIApplication sharedApplication].delegate;
WelcomeController *controller = [[WelcomeController alloc] init];
[controller createWelcome];
appDelegate.window.rootViewController = controller;
[appDelegate.window addSubview:[controller view]];
[appDelegate.window makeKeyAndVisible];

我的问题在第一行，因为它不会取消所有 RestKit 处理。在日志中，我看到了一些 ObjectMapping 操作，它们导致了EXC_BAD_ACCESS (SIGSEGV)错误。我找到了一种解决方法 - 延迟后切换控制器（使用performSelector:withObject:afterDelay）。但我正在寻找更好的解决方案。

ObjectMapping 操作是：

我正在使用最新版本的 RestKit。

从 RestKit 0.20.0 开始：

[[[RKObjectManager sharedManager] operationQueue] cancelAllOperations];

您是否有理由要求客户取消所有操作？通常你会要求 RKObjectManager 来完成这项工作。

[[[[RKObjectManager sharedManager] requestQueue] cancelAllRequests];
