How To Get Selected Value From UIPickerView

Question

I know that with a UIDatePicker, you can use something like:

NSDate *myDate = picker.date;

But I am using a UIPickerView in my view. How c

Answer 1

You have to use the didSelectRow delegate method, because a UIPickerView can have an arbitrary number of components. There is no "objectValue" or anything like that, because that's entirely up to you.

Answer 2

       NSInteger SelectedRow;
                   SelectedRow = [yourPickerView selectedRowInComponent:0];
                   selectedPickerString = [YourPickerArray objectAtIndex:SelectedRow];
                   self.YourTextField.text= selectedPickerString;

    // if  you want to move pickerview to selected row then 
 for (int i = 0; I<YourPickerArray.count; i++) {
  if ([[YourPickerArray objectAtIndex:i] isEqualToString:self.YourTextField.text]) { 
[yourPickerView selectRow:i inComponent:0 animated:NO];
 }
}

Answer 3

This is my answer

- (IBAction)Result:(id)sender 
{
   self.statusLabel.text = DataSource[[pickerViewTool selectedRowInComponent:0]];

}

Answer 4

This is what I did:

- (void)pickerView:(UIPickerView *)pickerView didSelectRow:(NSInteger)row inComponent:(NSInteger)component {

    selectedEntry = [allEntries objectAtIndex:row];

}

The selectedEntry is a NSString and will hold the currently selected entry in the pickerview. I am new to objective C but I think this is much easier.

Answer 5

You will need to ask the picker's delegate, in the same way your application does. Here is how I do it from within my UIPickerViewDelegate:

func selectedRowValue(picker : UIPickerView, ic : Int) -> String {

    //Row Index
    let ir  = picker.selectedRow(inComponent: ic);

    //Value
    let val = self.pickerView(picker,
                              titleForRow:  ir,
                              forComponent: ic);
    return val!;
}

Answer 6

Getting the selected title of a picker:

let component = 0
let row = picker.selectedRow(inComponent: component)
let title = picker.delegate?.pickerView?(picker, titleForRow: row, forComponent: component)
