我在服务器中有一些记录，当应用服务器的前台后台将发送所有记录时，从客户端我将所有数据保存到coredata中。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db中获取一些数据，但在这段时间我的应用程序被冻结，并且只有在完成所有更新和节省后才能正常工作。

答案 0 :(得分：5)
您是否看过附加到此问题的仪器跟踪？如果你：
您将看到所有工作都在主线程上完成，大部分时间都用在：
-[IXWebSocketDataManager webSocket: didReceiveMessage:] -[IXWebSocketDataManager checkResponseCode: indexvalue: isArray:] -[IXWebSocketDataManager updateSolicitationWithSyncDetails:] 其中任何一个都不应该在主线程上。
主要线程是用户界面更新仅。您的所有数据处理应该在后台运行，可以是NSOperation子类或GCD块等。从主线程中获取数据处理，您的性能将得到改善。
用于从网络检索数据的任何内容都返回主线程。这似乎是这个问题的根源。
