  • typical memory usage of an iphone app

    - by climbon
    According to Instruments 'Net Bytes' of my app are never more than 2MB yet sometimes I receive memory warning and the app crashes because some views on the stack are unloaded by force. I'd like to know what is the typical memory footprint where system would not send you memory warning and unload the views ? I have so far tried this on OS 3.1.2 on iphone 3GS and 3G and with 3G giving warning almost 80% of the time I test the app on it.

    - by Doug
    I am working on a website which I would like to work on iPhones, however I want it so they can tap and hold a button and have it continue firing the onclick event.

  • graphs and charts on the iPhone

    - by Jon
    My client has requested data to be presented in a graphical format on the iPhone (a pie chart or something similar). I am wondering how others have handled this - A.) deliver the raw data to the phone and somehow build the chart on the phone, or B.) have the back-end services build the chart and deliver it (png format) to the phone? Thanks for any advice.
