copied!<p>I'd use the last method you listed (Asynchronous Table Cell Lookup) but only look images for the current records being displayed. I overload the UIScrollViewDelegate methods to find out when a user has stopped scrolling, and then only start making requests for the current visible cells. </p> <p>Something like this (this is slightly modified from a tutorial I found on the web which I can't find now, apologies for not citing the author) :</p> <pre><code>- (void)loadContentForVisibleCells { NSArray *cells = [self.table visibleCells]; [cells retain]; for (int i = 0; i < [cells count]; i++) { // Go through each cell in the array and call its loadContent method if it responds to it. AddressRecordTableCell *addressTableCell = (AddressRecordTableCell *)[[cells objectAtIndex: i] retain]; [addressTableCell loadImage]; [addressTableCell release]; addressTableCell = nil; } [cells release]; } - (void)scrollViewDidEndDecelerating:(UIScrollView *)scrollView; { // Method is called when the decelerating comes to a stop. // Pass visible cells to the cell loading function. If possible change // scrollView to a pointer to your table cell to avoid compiler warnings [self loadContentForVisibleCells]; } - (void)scrollViewDidEndDragging:(UIScrollView *)scrollView willDecelerate:(BOOL)decelerate; { if (!decelerate) { [self loadContentForVisibleCells]; } } </code></pre> <p>Once you know what address records are currently visible, just doing a search for those (5 -7 records probably) will be lightning fast. Once you grab the image, just cache it in a dictionary so that you don't have to redo the request for the image later.</p>
