iOS How do I tell my app to display the next few table view cells?

[moonman239]

There is a table view in a view controller. This table view's content is loaded dynamically. There are some cells that, due to space constraints, are not being displayed in the view. I don't want the user to scroll down. I want the app to skip to the last few cells once it can verify that the user looked at all of the content that was already presented in the table view.

I am approaching a solution. Here's the code I have so far:

@implementation UITableView (displayOtherCells)
-(void)displayOtherCells
{
    
    NSArray *visibleCells = [self visibleCells];
    for (NSInteger i = [visibleCells count]; i < [self numberOfRowsInSection:1]; i++) {
        NSIndexPath *indexPathOfCell = [NSIndexPath indexPathForRow:i inSection:1];
        UITableViewCell *currentCell = [[self dataSource] tableView:self cellForRowAtIndexPath:indexPathOfCell];
    }
}
@end

OK, here's my untested solution:

@implementation UITableView (displayOtherCells)
-(void)displayOtherCells
{
    
    NSArray *visibleCells = [self visibleCells];
    for (NSInteger i = [visibleCells count]; i < [self numberOfRowsInSection:0]; i++) {
        NSIndexPath *indexPath = [NSIndexPath indexPathForRow:i inSection:0];
        [self scrollToRowAtIndexPath:indexPath atScrollPosition:UITableViewScrollPositionNone animated:NO];
    }
}
@end

It is odd that you're calling

scrollToRowAtIndexPath:atScrollPosition:animated:

in a loop.

I would expect your solution to involve calculating a reasonable value of indexPath, and then scrolling to it.

Hope that helps

How can you know what the user has looked at?
