You want the range value to change as you move the slider and also save that value for when the user comes back to this screen ? — CW0007007, Apr 23 '14 at 14:58

Call [self.tableView reloadData]; each time the slider moves. Ensure the value you want to be dynamic is a property and is set by the slider.

If you do not want to reload the entire tableView you can also reload the cell with this function:

- (void)reloadRowsAtIndexPaths:(NSArray *)indexPaths withRowAnimation:(UITableViewRowAnimation)animation

Come on, just think about it yourself, is it a good decision or not? Sorry for being harsh but I don't think it's a very good way of solving the problem at hand. – Sergey Grischyov Apr 23 '14 at 15:49
Just reload that one cell and not the whole table view. – CW0007007 Apr 23 '14 at 15:55
what the solution for this question without reloading a table? @SergiusGee – Priyank Gandhi Apr 23 '14 at 18:45
The selected solution is great now that you don't have to reload the entire `UITableView`. Good choice. Upvoting. – Sergey Grischyov Apr 24 '14 at 10:36

You should use addTarget for your UISlider. Everytime the events will be called, you can change the value inside your data model and reloadTable to show the changed value.

Have a look at this example
