Implementing UITableView with three "columns" in MapView [Swift] - ios

Question

i'm trying to implement the following design with MapBox and a TableView.
I've been thinking about it and I wanted to use a UITableView for the results, but as far as I know, it's only possible to have data and detail on the left & right side. Is there an alternative to UITableView ?
If not, i'm also facing the problem that my "root"-View is a MapView (from MapBox) and that I can't use the MapViewController as UITableViewController nor as UITableViewDelegate/UITableViewDataSource. Is it possible to Embed the MapView in another View ?
If you need any more information, just let me know. And thank you in advance.

You know wrong. You can include any interface you want in a table view cell. Just make this a custom cell and design it as desired.

Assuming that you have a UIViewController in your storyboard or xib called ViewController which has both a UITableView and an MKMapView (or whatever you are using) correctly connected to the two outlets in the code below:
import UIKit
import MapKit
class ViewController: UIViewController, UITableViewDataSource, UITableViewDelegate, MKMapViewDelegate {
#IBOutlet weak var mapView: MKMapView!
#IBOutlet weak var tableView: UITableView!
override func viewDidLoad() {
super.viewDidLoad()
// Now tell the system that we are going to reference our
// hand-made table cell from a xib called "MyCell"
self.tableView.register(UINib(nibName: "MyCell", bundle: nil), forCellReuseIdentifier: "MyCell")
// These next you can do here, or in IB...
self.tableView.dataSource = self
self.tableView.delegate = self
}
override func didReceiveMemoryWarning() {
super.didReceiveMemoryWarning()
// Dispose of any resources that can be recreated.
}
//MARK: - TableViewDataSource
// ANY ViewController can do this, if we register the class as conforming
// to the `UITableViewDataSource` protocol
func numberOfSections(in tableView: UITableView) -> Int {
return 1
}
func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
return 3
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
// Get a reference to an instance of our very own UITableViewCell subclass,
// Which we registered in `viewDidLoad`
let c = self.tableView.dequeueReusableCell(withIdentifier: "MyCell", for: indexPath) as! MyCell
// Whatever controls/outlets we have put in our cell subclass,
// we need to populate with data now... (I just did a label)
c.cellNumber?.text = "\(indexPath.row)"
return c
}
//MARK: - TableViewDelegate
//... implement whatever funcs you need ...
//MARK: - MKMapViewDelegate
//... implement whatever funcs you need ...
}
You then need to create the following code, AND a stand-alone xib (called in this case "MyCell.xib"). The xib should contain all of the controls you want in your table cell. In my example it has only one control, the UILabel referenced as cellNumber.
To make the xib, choose "File->New File->User Interface->Empty" from the Xcode menu, then drop a UITableViewCell into the xib from the palette. Make sure you change the class of the cell from UITableViewCell to MyCell. Add whatever controls (and constraints between them) that you need. Obviously, connect all of your controls to relevant #IBOutlets in this class.
class MyCell: UITableViewCell {
// Create `#IBOutlet weak var ...` for all of the controls in your cell here
#IBOutlet weak var cellNumber: UILabel!
override init(style: UITableViewCellStyle, reuseIdentifier: String?) {
super.init(style: style, reuseIdentifier: reuseIdentifier)
self.configureCell()
}
required init?(coder aDecoder: NSCoder) {
super.init(coder: aDecoder)
self.configureCell()
}
func configureCell() {
// Your stuff to load up the IBOutlet controls of your cell with defaults.
// You will be able to override these when the instantiated cell is passed to
// `tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell`
// in the `UITableViewDataSource`
}
