uitableview with multiple sections
Uitableview is very important part of iOS ecosystem. Everything from songs playlist to weight trackers use tableview to show data. When you have 10,000 songs or number of rows in your table then its difficult to find right information. So we split tableviews in sections. Then its easier to find right information.
1. First lets set up the x code project as usual. Create new single view application X code project. Set project name to tableview with sections & save it on desktop.
2. Go to main storyboard & select view controller & delete it. Add tableview controller in main storyboard.
3. Select tableview controller & make it initial view controller
4. Now delete view controller swift file & add new cocoa touch class file of class uitableviewcontroller
5. Go to main storyboard; select table view controller & set its class to TableViewController
6. Now create an array called section to store section title & another array of array called items section row content of tableview as follows
class TableViewController: UITableViewController
{
// Below explained code should be within the TableViewController Class. I separate them to explain it individually.
}
func viewdisload
{
let section = ["pizza", "deep dish pizza", "calzone"]
let items = [["Margarita", "BBQ Chicken", "Pepperoni"], ["sausage", "meat lovers", "veggie lovers"], ["sausage", "chicken pesto", "prawns", "mushrooms"]]
}
7. Add new method for setting name for each section & set number of sections as follows.
// MARK: – Table view data source
override func tableView(tableView: UITableView, titleForHeaderInSection section: Int) -> String?
{
return self.section\[section\]
}
override func numberOfSectionsInTableView(tableView: UITableView) -> Int
{
// #warning Incomplete implementation, return the number of sections
return self.section.count
}
8. Set number of rows per section as follows
override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int
{
// #warning Incomplete implementation, return the number of rows
return self.items\[section\].count
}
9. Uncomment cellForRowAtIndexPath method & add following code
override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell
{
let cell = tableView.dequeueReusableCellWithIdentifier("tableCell", forIndexPath: indexPath)
// Configure the cell...
cell.textLabel?.text = self.items[indexPath.section][indexPath.row]
return cell
}
10. Now go to main storyboard & select the prototype cell. Set its identifier to tableCell. Also set style to Basic
Now build and run app in iPhone 5s You will see the table populated with items from number array.
