Tableview Sections

Goals

• Recognize UITableView as a display pattern and learn more about customizing it.
• Learn how to implement sections (with headers) in a table view.
• Stimulate thinking about how custom objects can be displayed using a tableview.

We've been working with tableviews, but so far we've only put out a unified list based off a single array. Let's get into sections as well as displaying custom objects.

Instructions

1. Open the project — there's already a blank tableview linked to a custom class set up for you.
2. Make a FISStudent class with a public NSArray property called favoriteThings.
3. In FISTableViewController, make an array property called students.
4. In your tableView controller's viewDidLoad, make some FISStudents and give them all names. Then fill in their favoriteThings properties with strings of their favorite things. No specific amount necessary, be creative or simply ask people around you!
5. Set these students to your TVcontroller's students property.
6. Set up your tableView to match the following:
   • each student should have their own section (hint: numberOfSectionsInTableView:)
   • set up tableView:numberOfRowsInSection: so that the rows in each section match that student's favoriteThings.
   • set your cell's textLabel to a favorite thing, and its detailTextLabel to its row index.
7. Cool, everyone's favorite things are listed, but theres no distinction between sections... implement tableView:titleForHeaderInSection:. using the student'sname` property.
8. Houston, we have sections! But this is still kinda hard to read, it's just a big list of text after all. Implement tableView:indentationLevelForRowAtIndexPath: to clean it up a bit.

Advanced

Add the following properties to your FISStudent:

• favoriteFood
• favoriteColor
• favoriteMusicalArtist
• favoriteGame

Set these for your student objects in your viewDidLoad. Now instead of using favoriteThings in your tableView data source, have it use these new properties to fill in the rows.

Then if you wanna make it real fancy, include the property name in the cell (eg "Food: Pizza" as opposed to "Pizza")
