I need a grouped UITableView similar to the one for Twitter accounts in Settings app:
Static is just a provision on top of dynamic layout. Basically static is a WYSIWYG.
If you are not resistant to experiment with values, I would recommend go dynamic. There are hundreds of examples available, such as this and this.
As you go further, you would see yourself diverging towards two options when customizing dynamic table views:
UITableViewCell (more effort , but good in the long run). Again, follow this.UITableViewCell properties inside cellForRowAtIndexPath: (less effort and quick result but may or may not be performance-friendly due to possible redrawing)The possibilities are endless, such as here where cell background view is customized.
