Country code selection using Radio Button In table view Swift

In this blog I have demonstrated how to use radio button to select country in table view.

I am using two radio button image “radioButtonUnchecked” “radioButtonChecked” to show which coutry is selected.In this example i have created two files TableViewController, TableViewCell .To access "TableViewCell" Inside “ TableViewController" write this code inside tableView cellRowAtIndexPath function

  func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
        let cell:TableViewCell=tableView.dequeueReusableCellWithIdentifier(“Cell", forIndexPath: indexPath) as! TableViewCell
}
 

In TableViewController write this code :-

 import UIKit

class TableViewController: UITableViewController {

    var countryArray=["Afghanistan","Albania","Algeria","AmericanSamoa","Andorra","Angola","Anguilla","Haiti","Honduras","Hong Kong","Hungary","Iceland","India","Indonesia","Iran","Iraq","Ireland","Isle of Man","Israel","Italy","Jamaica","Japan","Jersey","Jordan","Kazakhstan","Kenya"]
   var selectedIndex:NSIndexPath?
    override func viewDidLoad() {
        super.viewDidLoad()

        // Uncomment the following line to preserve selection between presentations
        // self.clearsSelectionOnViewWillAppear = false

        // Uncomment the following line to display an Edit button in the navigation bar for this view controller.
        // self.navigationItem.rightBarButtonItem = self.editButtonItem()
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

    // MARK: - Table view data source

    override func numberOfSectionsInTableView(tableView: UITableView) -> Int {
        // #warning Potentially incomplete method implementation.
        // Return the number of sections.
        return 1
    }

    override func tableView(tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        // #warning Incomplete method implementation.
        // Return the number of rows in the section.
        return countryArray.count
    }

    
    override func tableView(tableView: UITableView, cellForRowAtIndexPath indexPath: NSIndexPath) -> UITableViewCell {
       // let cell = tableView.dequeueReusableCellWithIdentifier("reuseIdentifier", forIndexPath: indexPath) as! UITableViewCell
        
        
        let cell:TableViewCell=tableView.dequeueReusableCellWithIdentifier("Cell", forIndexPath: indexPath) as! TableViewCell
        
        cell.country.text=countryArray[indexPath.row]

        cell.selectionStyle = UITableViewCellSelectionStyle.None;
        
        if (selectedIndex == indexPath) {
            cell.radioButton.setImage(UIImage(named: "radioButtonChecked"),forState:UIControlState.Normal)
        } else {
            cell.radioButton.setImage(UIImage(named: "radioButtonUnchecked"),forState:UIControlState.Normal)
        }


        // Configure the cell...

        return cell
    }
    
    
    override func tableView(tableView: UITableView, didSelectRowAtIndexPath indexPath: NSIndexPath) {
        tableView.deselectRowAtIndexPath(indexPath, animated: true)
        let row = indexPath.row
        println(countryArray[row])
        selectedIndex = indexPath
        tableView.reloadData()
    }
    
}
 

In TableViewCell write this code:-

 




import UIKit

class TableViewCell: UITableViewCell {

    @IBOutlet weak var radioButton: UIButton!
    
    @IBOutlet weak var country: UILabel!
    override func awakeFromNib() {
        super.awakeFromNib()
        // Initialization code
    }

    override func setSelected(selected: Bool, animated: Bool) {
        super.setSelected(selected, animated: animated)

        // Configure the view for the selected state
    }

}
