我正在为 RESTFUL Web 服务使用 Restkit 框架。
我的 Resoucemanager 即 TaskManager 和 TaskDashboardCountManager 发生冲突。当我调用方法时
[[TaskDashboardCountManager sharedManager] loadTaskCount:^(NSDictionary *task) {}];
我得到了例外
'NSInvalidArgumentException'，原因：'-[TaskDashboardCountManager loadTask:failure:]:
loadTask 是 TaskManager 的方法，但它是使用 TaskDashboardCountManger 调用的。我该如何解决？
