UIPickerView as inputView for UITextView swift

Question

I have used UIPickerView as inputView for UITextView. The selectRow: function doesn't select properly for alternate time

Here is the code

func textViewDidBeginEditing(_ textView: UITextView) {
    let inputView = UIView(frame: CGRect(x: 0,y: 0, width: self.view.frame.width, height: 240))
    let codePicker = UIPickerView(frame: CGRect(x: 0, y: 0, width: self.view.bounds.width, height: 240))
    codePicker.tag = 2

    if codePicker.dataSource == nil {
        codePicker.dataSource = self
    }
    if codePicker.delegate == nil {
        codePicker.delegate = self
    }

    codePicker.showsSelectionIndicator = true
    print("selectedBankRow: \(selectedRow)")
    codePicker.selectRow(selectedRow, inComponent: 0, animated: true)
    inputView.addSubview(codePicker)
    textView.inputView = inputView
    return
}

The print statement print correct row but the selectRow: function selects the previous to the previous value which was selected, what could be the error? Even the status bar goes black each alternate time only for this UITextView interaction.

Don't create UIPickerView every time

Create Global Object

var codePicker = UIPickerView()

and in viewDidLoad Method

add following code

let inputView = UIView(frame: CGRect(x: 0,y: 0, width: self.view.frame.width, height: 240))
codePicker = UIPickerView(frame: CGRect(x: 0, y: 0, width: self.view.bounds.width, height: 240))
codePicker.tag = 2
codePicker.dataSource = self
codePicker.delegate = self

codePicker.showsSelectionIndicator = true
print("selectedBankRow: \(selectedRow)")
codePicker.selectRow(selectedRow, inComponent: 0, animated: true)
inputView.addSubview(codePicker)
textView.inputView = inputView

as you solved Status bar issue with

IQKeyboardManager.sharedManager().canAdjustAdditionalSafeAreaInsets = true

Hope it is helpful
