title: How to use one UIPickerView for two textfields in one view?
body: <p>I have 2 textfields in one view. I want to populate each using a pickerview. Currently I have succesfully made one picker with one textfield working perfectly but once I edited the code to make it working with two textfield it does not working as expected. Any help will be much appreciated.</p>
  
  <p>Below is my code : </p>
  
  <pre><code>#import "TestPickerVC.h"
  
  @interface TestPickerVC () &lt;UITextFieldDelegate, UIPickerViewDataSource, UIPickerViewDelegate&gt;
  {
      NSArray *aktivitiArray;
      NSArray *penganjurArray;
  }
  
  @end
  
  @implementation TestPickerVC
  
  - (void)viewDidLoad {
      [super viewDidLoad];
      // Do any additional setup after loading the view.
  
      self.penganjurTextField.delegate = self;
      self.aktivitiTextField.delegate = self;
  
      aktivitiArray = @[@"apple", @"samsung", @"motorola", @"nokia"];
      penganjurArray = @[@"jimbit", @"ayam", @"kambing", @"emergency"];
  
  
  //    self.aktivitiTextField.inputView = self.pickerView1;
  //    self.penganjurTextField.inputView = self.pickerView2;
  
      self.pickerView = [[UIPickerView alloc] init];
      self.pickerView.delegate = self;
      self.pickerView.dataSource = self;
  
  
      self.aktivitiTextField.inputView = self.pickerView;
  
      self.penganjurTextField.inputView = self.pickerView;
  
      self.aktivitiTextField.tag = 1;
      self.penganjurTextField.tag = 2;
  
  
  
  //    if (self.aktivitiTextField.tag == 100) {
  //        self.aktivitiTextField.inputView = self.pickerView;
  //        self.pickerView.tag = 1;
  //        NSLog(@"pickerview tag : %d", (int)self.pickerView.tag);
  //    } else if (self.penganjurTextField.tag == 200) {
  //        self.penganjurTextField.inputView = self.pickerView;
  //        self.pickerView2.tag = 2;
  //        NSLog(@"pickerview tag : %d", (int)self.pickerView2.tag);
  //
  //    }
