Choose which ViewController to switch to by using Picker View - ios

Question

I am creating a restaurant app, in which the user could select which restaurant they would like to do on the first screen. After they've made their selection the user should press the begin button and it will take it to that View Controller
I have no idea how to get started, any help would be appreciated.

Answer 1

Set label text in picker didselect delegate . then on button action method decide which vc to open on the basis of label text.

Answer 2

Used button action is Done Button that we embed with picker to make final selection.
Use the following code: Works fine
import UIKit
class PickerViewController: UIViewController,UIPickerViewDataSource, UIPickerViewDelegate {
#IBOutlet weak var pickerVieww: UIPickerView!
var viewControllerArray = [String]()
var value = Int()
override func viewDidLoad() {
super.viewDidLoad()
pickerVieww.delegate = self
pickerVieww.dataSource = self
viewControllerArray = ["controller1","controller2","controller3"]
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return viewControllerArray.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return viewControllerArray[row]
}
func pickerView(_ pickerView: UIPickerView,didSelectRow row: Int,inComponent component: Int)
{
if(row == 0) {
value = 0
}
else if(row == 1) {
value = 1
}
else{
value = 2
}
}
#IBAction func swicthToController(_ sender: Any) {
if value == 0{
let vc = self.storyboard?.instantiateViewController(withIdentifier: "first") as! asasasViewController
self.present(vc, animated: true, completion: nil)
}
if value == 1{
let vc = self.storyboard?.instantiateViewController(withIdentifier: "second") as! secondViewController
self.present(vc, animated: true, completion: nil)
}
if value == 2{
let vc = self.storyboard?.instantiateViewController(withIdentifier: "third") as! thirdViewController
self.present(vc, animated: true, completion: nil)
}
}
}
