I am developing a application which receives 600-700 KB of XML data from the server. I have to do some manipulations in that data so once received the data the memory increases to 600 KB to 2 M.B. Already view occupied 4 M.B of memory in the application.
So while processing the XML data i m doing some manipulation(pre-parsing) and the memory increases to 600 K.B to 2 M.B and finally decreases to 600 K.B. due to increase in memory, application gives the memory warning. While getting memory warning i m releasing all the views in the navigation controller but it releases only 1 M.B of memory. Even though I release all the views the application is crashing.
Please help me out in this issue. It happens in iPad 4.2.

Thanks in advance

    There’s no magical answer here. You’re using too much memory and you need to figure out how to use less. Without knowing more about your application it’s difficult to be specific, though clearly loading in nearly 1Mb of data and playing around with it isn’t helping.

    Maybe you can stream the data rather than loading it all into memory? There’s an open source library that helps: StreamingXMLParser.

    Also, your view sounds huge (over a megabyte!). I’m sure there’s some optimisation that can be performed there. Use Instruments to see where your memory is being used.
