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 can i similarly get the value selected   Or do I have to setup didSelectRow type of method to do this     Update   This code works for picker with 1 component     NSInteger row   NSString  weightSelected     row    repPicker selectedRowInComponent 0    weightSelected    pickerArray objectAtIndex row        I tired this code for my picker with 2 components  but it is freezing     NSInteger row1  row2   NSString  weightSelected1   NSString  weightSelected2     row1    repPicker selectedRowInComponent 0    row2    repPicker selectedRowInComponent 1    weightSelected1    pickerArray objectAtIndex row1    weightSelected2    pickerArray objectAtIndex row2    NSString  weightSelected    NSString stringWithFormat           weightSelected1  weightSelected2

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

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  - gt  String          Row Index     let ir    picker selectedRow inComponent  ic          Value     let val   self pickerView picker                                titleForRow   ir                                forComponent  ic       return val

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

You can access the selected row for a given component using the following method   -  NSInteger selectedRowInComponent  NSInteger component   Otherwise  implementing the delegate function is the only other option

You can get the text of the selected item in any section of the picker using the same function that the pickerView does  from your custom ViewController class   - NSString   pickerView  UIPickerView   pickerView titleForRow  NSInteger row forComponent  NSInteger component   using the selected item   myPickerView selectedRowInComponent 0    so to set the text of a label in a custom cell using the currently selected value from the 2nd section of myPickerView  a property of your view controller probably    cell label setText  self pickerView myPickerView titleForRow  myPickerView selectedRowInComponent 1  forComponent 1      Just change both  1s to  2s  etc for each section
