title: How to prepare UIPickerView with months and years in ios?
body: <p>I'm working on Preparing UIPickerView with months and year in iOS.</p>
  
  <p>Below is my code.</p>
  
  <p>in <strong>viewdidload</strong> :</p>
  
  <pre><code>//Array for picker view
  monthsArray=[[NSMutableArray alloc]initWithObjects:@"Jan",@"Feb",@"Mar",@"Apr",@"May",@"Jun",@"Jul",@"Aug",@"Sep",@"Oct",@"Nov",@"Dec",nil];
  
  
  NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
  [formatter setDateFormat:@"yyyy"];
  NSString *yearString = [formatter stringFromDate:[NSDate date]];
  
  
  yearsArray=[[NSMutableArray alloc]init];
  
  
  for (int i=0; i&lt;13; i++)
  {
      [yearsArray addObject:[NSString stringWithFormat:@"%d",[yearString intValue]+i]];
  }
  
  myPickerView = [[UIPickerView alloc] initWithFrame:CGRectMake(0, 200, 320, 200)];
  myPickerView.delegate = self;
  myPickerView.showsSelectionIndicator = YES;
  [myPickerView selectRow:0 inComponent:0 animated:YES];
  [self.view addSubview:myPickerView];
  </code></pre>
  
  <p><strong>Picker view delegate methods:</strong></p>
  
  <pre><code>// tell the picker how many components it will have
  - (NSInteger)numberOfComponentsInPickerView:(UIPickerView *)pickerView
  {
  return 2;
  }
  
  // tell the picker how many rows are available for a given component
  - (NSInteger)pickerView:(UIPickerView *)pickerView numberOfRowsInComponent:(NSInteger)component
  {
  NSInteger rowsInComponent;
  if (component==0)
  {
      rowsInComponent=[monthsArray count];
  }
  else
  {
      rowsInComponent=[yearsArray count];
  }
  return rowsInComponent;
  }
  
  
  
  - (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component
  {
  
  NSString * nameInRow;
  if (component==0)
  {
      nameInRow=[monthsArray objectAtIndex:row];
  }
  else  if (component==1)
  {
      nameInRow=[yearsArray objectAtIndex:row];
  }
  
  return nameInRow;
  }
  
  
  // tell the picker the width of each row for a given component
  - (CGFloat)pickerView:(UIPickerView *)pickerView widthForComponent:(NSInteger)component
  {
  CGFloat componentWidth ;
  
  if (component==0)
  {
      componentWidth = 100;
  }
  else  {
      componentWidth = 100;
  }
  
  return componentWidth;
  }
  </code></pre>

  <p><strong>But in the current year , the months from Jan to Oct have expired. How to disable those years in my picker only for the current year dynamically. Those months should be available for the remaining years.</strong></p>
  
  <p>Actually the real output is,</p>
  
  <p><img src="https://i.stack.imgur.com/ZNph2.png" alt="enter image description here"> </p>
  
  <p>In above, the expired months in the current year should be disabled in UI.</p>
  
  <p><strong><em>Any comments or suggestions would be appreciated.</em></strong></p>
