How can I speed up a UITableView?

Question

I have a UITableView with about 400 cells in 200 sections and it\'s a little sluggish in responding to user interaction (scrolling, selecting cells.) I\'ve made sure the met

Answer 1

1. use a shared image instance for the background (you alloc/init/release one for every time a new cell is created). When your table view is big , this means that the background X cells in memory takes much more memory than it should.

   instead of
   cell.backgroundView= [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"cell gradient2.png"]];
   just use :
   cell.backgroundView= [SomeHelperClass sharedBackgroundUIImageResource];

2. If that doesn't help , use CG instead of labels and other subviews (a screenshot will help here.. to know what we're talking about).
