Indeed, when knowing how to work with UITableViews in a more advanced level, then you can create more flexible apps that make your users happier.
When creating iOS applications, the need to pick a value from a list while displaying an UITableView comes up quite often. One obvious solution to that matter, and the hard one in most cases, is to load another UIView which may contain an UIPickerView or an UITableView that will list the values you need, let the user pick the value and then get back into your table and set the picked (by the user) value. Another solution, more attractive and probably easier for the user is to display the list you need inside the UITableView that’s been shown. Perhaps that approach sounds more difficult, but once you try it you’ll find out yourself how fast, easy and beautiful solution is.
