i am trying to assign my pickerview data but what data type member is picker view? when i use text it says the error "value of type uipickerview has no member text"
dateLabel.text = shiftItem.day
timing.text = shiftItem.slot
the ibaction is
@IBOutlet weak var timing: UIPickerView!
so for label or text field the data type would be text but what is it for pickerview? this may seem like a dumb question but i could not find the answer anywhere
also, how can i pass the data a user has selected on a pickerview to another view controller?
thank you so much for all the help!

UIPickerView doesn't have any property named text. You have to use an array of String as it's datasource. Here is an example.
class ViewController: UIViewController, UIPickerViewDelegate, UIPickerViewDataSource {
@IBOutlet weak var pickerView: UIPickerView!
let pickerData: [String] = ["Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6"]
override func viewDidLoad() {
super.viewDidLoad()
pickerView.delegate = self
pickerView.dataSource = self
}
func numberOfComponents(in pickerView: UIPickerView) -> Int {
return 1
}
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return pickerData.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return pickerData[row]
}
}
CodePudding user response：
func pickerView(pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) { // use the row to get the selected row from the picker view // using the row extract the value from your datasource (array[row]) }
CodePudding user response：
Please use the below code for it. Picker View doesn't have a text member.
class HomeController: UIViewController {
@IBOutlet weak var pickerView: UIPickerView!
var dataArray: [String] = ["Aman", "Raju", "Amit", "Aashish", "Sheshnath"]
override func viewDidLoad() {
super.viewDidLoad()
pickerView.delegate = self
pickerView.dataSource = self
// Use this method for initial text from your data array
pickerView.selectRow(1, inComponent: 0, animated: true)
}
}
extension HomeController: UIPickerViewDelegate, UIPickerViewDataSource { func numberOfComponents(in pickerView: UIPickerView) -> Int { return 1 }
func pickerView(_ pickerView: UIPickerView, numberOfRowsInComponent component: Int) -> Int {
return dataArray.count
}
func pickerView(_ pickerView: UIPickerView, titleForRow row: Int, forComponent component: Int) -> String? {
return dataArray[row]
}
}
