保存到核心数据应用程序被冻结几秒钟

我有一些logging在服务器，当背景前台应用程序服务器将发送所有logging，从客户端我节省所有数据到coredata。 保存时我需要检查这些数据是否已经存在，有时我需要在保存之前从数据库中获取一些数据，但在这段时间，我的应用程序被冻结了，只有在所有的更新和储蓄完成后，它才能正常工作。

你看过你附在这个问题上的仪器踪迹吗？ 如果你：

1. 通过线程分隔调用树
2. 反转呼叫树
3. 隐藏系统库

你会看到你的所有工作都在主线上完成，大部分时间都花在：

• -[IXWebSocketDataManager webSocket: didReceiveMessage:]
• -[IXWebSocketDataManager checkResponseCode: indexvalue: isArray:]
• -[IXWebSocketDataManager updateSolicitationWithSyncDetails:]

这些都不应该在主线程上。

主线程仅用于用户界面更新。 所有的数据处理都应该在后台运行，不pipe是在NSOperation子类还是GCD块之类。 从主线程获取数据处理，性能将得到改善。

无论你用什么来从networking中检索数据，都会在主线程中返回。 这似乎是这个问题的根源。
