Adding a number picker to each table view cell

Question

I am very new to iOS development. Currently, I am trying to develop an iPad app for taking orders in a restaurant. The UI should be like this: http://www.dhtmlx.com/blog/wp-content/uploads/2011/02/ipad_menu_final.jpg As people suggested, it would be easier to start by creating a Master/Detail project as the basic structure. After going through a couple of tutorials, I know how to display detail contents when I select rows at master view. Now, my assumption is to add an UITableView to the detail view controller, and at each UITableView Cell, I want to add some text to describe the menu item and also an UIPickerView to let the user select the quantity of each item (like the pic in the above link). Am I on the right track? How can I add an UITextField and UIPickerView to each UITableView cell programmatically? Are there any examples or tutorials teach me how to do this? Thanks in advance.

Answer 1

1 - THE VIEW : Create a UITableViewCell subclass (ex: MyMenuItemCell), with the properties you need

• a UIImageView for the picture
• a UILabel for the price (with some CALayer cornerRadius , backgroundColor , and borderColor tweaking)
• another UILabel for the title describing the product
• another UILabel for the description
• a UIButton to get userAction, but handle that in another class, as this cell is the VIEW, and should hold no control logic, this is the CONTROLLER 's part.

2 - THE CONTROLLER

You UIViewController should implement <UITableViewDatasource, UITableViewDelegate> . (or it can directly be a UITableViewController subclass, which provides some generic benefits, like moving the tableView when a keyboard is displayed. If you choose this 2nd option, and create the viewController programmatically, be sure to use the initWithStyle: method)

3 - BIND VIEW with CONTROLLER

However you choose to enable 'quantity pick' :

• with some UIStepper (+ and - buttons) linked to a UILabel

or

• in some dedicated UIPickerView displayed in a UIViewController embedded in a UIPopoverController

(or any other design you see fit)

you should write the code that triggers this action handling IN your controller, when UITableViewCell are instantiated / reused, in UITableViewDatasource method providing cells instances :
-(UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath
