While saving to core data app getting frozen for few seconds

Question

I have some records in server, when background to foreground the app server will send all the records and from client side i'm savings all data into coredata. While saving i need to check whether those data are already exist or not,and sometimes i need to fetch some data from db before save, but in these time my app became frozen, and its working fine only after all updates and savings are done.

Answer 1

Did you look at the Instruments trace that you attached to this question? If you:

1. separate the call tree by thread
2. invert the call tree
3. hide system libraries

You will see that all of your work is being done on the main thread and that most of the time is being spent in:

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

None of which should be on the Main thread.

The main thread is for User Interface updates ONLY. All of your data processing should be running in the background, either in a NSOperation subclass or a GCD block or something. Get that data processing off the main thread and your performance will improve.

Whatever you are using to retrieve the data from the network is returning on the main thread. That seems to be the source of this problem.
