    say i have a table view, that will show a text and a icon on it.
    the list of the table is am xml file, which includes a text and a image link for each cell.
    click on the cell to navigate to second detailed level.
    i saw many apps implemented this. first show a place holder icon, and then update it when the actual one finishes downloading.
    could someone tell me how to do this? the general pattern. i wrote one and ended up crashing easily.

    Open the Xcode documentation window.
    Type LazyTableImages into the search box.
    Look at the sample code.
