iPhone UIViewController Lag

Question

I have a 'detail' page where I am displaying info for a club. The page is a UIViewController and consists of buttons and labels to acheive this look (like small grouped tables). When I load this page on a device, it lags a bit, more than any other view in my app.

I assume its because I have quite a few objects on the view controller. Does anyone have any suggestions on how to reduce this lag? Or how to achieve the look the 3 smaller tables like this(grouped) in a different way?

Thanks.

Answer 1

You could try making custom tablecells and use UITableView instead?

Answer 2

You could just make the view a UITableView using UITableViewStyleGrouped style, and then programmatically create the cells for each row. Overriding

- (NSString *)tableView:(UITableView *)tableView titleForHeaderInSection:(NSInteger)section

gets you your titles like "Meeting Information" and "Contact", and overriding

- (CGFloat)tableView:(UITableView *)tableView heightForRowAtIndexPath:(NSIndexPath *)indexPath

gets you correct sizing on each table cell. If the text in "General Information" is not going to be a constant size, you can use the

-sizeWithFont::(UIFont *)font

method of NSString in your heightForRowAtIndexPath implementation.

Answer 3

The issue is not likely your interface design. UI drawing is pretty snappy usually. The things that slow it down are accessing data. If you have a large data set you are searching you might look at ways to speed that up.
