I need to place a radio button in tableview custom cell. whenever user clicks the tableview cell or button then radio button needs to work. I tried by using below code but didn't execute well.
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:TableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! TableViewCell
cell.country.text = self.animals[indexPath.row]
cell.selectionStyle = UITableViewCellSelectionStyle.none;
if selectedRows.contains(indexPath)
{
cell.radioButton.setImage(UIImage(named:"check.png"), for: .normal)
}
else
{
cell.radioButton.setImage(UIImage(named:"uncheck.png"), for: .normal)
}
return cell
}
Here's a great solution for creating radio buttons in a UITableView
using a storyboard that requires zero code - and has 2 great Cool Tips!!
Make sure your table view is set to Single Selection , and to use Static cells .
Add a Basic cell, set the image to be your unchecked button image, and make sure the selection style is Default
UIView
into the cell's content view, behind the text label. As you're using a basic cell, you won't be able to drop it directly into the cell, you'll need to drag it into onto the Document Outline on the left instead. Then hook this up to the cell's selected background view outlet. When a cell is selected (or highlighted), this view will be displayed in the background. In this case, we're going to use it to prevent the grey background appearing, so set its colour to Clear . Note that it doesn't matter what size the view is, and there's no need to set any constraints - it's automatically sized to match the cell at runtime. In your TableViewCell
class why don't you create a data source element and override the didSet
for it. also in your data source for the UITableView
I would recommend an array of something more than just a String
.
I haven't compiled the below so this is just an idea.
import UIKit
class TableViewCell : UITableViewCell {
var data: Animal? {
didSet {
self.country.text = data.description
if (data.isSelected) {
self.radioButton.setImage(UIImage(named:"check.png"), for: .normal)
} else {
self.radioButton.setImage(UIImage(named:"uncheck.png"), for: .normal)
}
}
}
}
in your view controller you will of course have to set the isSelected
property whenever a row is tapped.
func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
var animal = self.animals[indexPath.row]
animal.isSelected = !animal.isSelected
}
func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
let cell:TableViewCell = self.tableView.dequeueReusableCell(withIdentifier: cellReuseIdentifier) as! TableViewCell
cell.data = self.animals[indexPath.row]
}
and for your Animal
maybe something like this:
struct Animal {
var description: String
var isSelected: Bool
}
