title: How can I put an image in this UIPickerView?
body: <p>I don't have any idea how can I create a custom UIPickerView with an image on the side of the text.</p>
  
  <p>I've been searching for a method and I just found this:</p>
  
  <pre><code>- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row
  forComponent:(NSInteger)component reusingView:(UIView *)view
  </code></pre>
  
  <p>But I don't know how I can use that.</p>
  
  <p>These are my arrays:<br>
  All works perfectly, I just want to put a diferent image in each row, with 10 different colors.
  The colors will be the same for the 3 components but different in each row.
  like this image. <a href="http://www.fv.uan.edu.mx/file.php/77/imagenes/colores_resistencias.jpg" rel="nofollow">LINK!!!</a></p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
  
      Colores1 = [[NSMutableArray alloc] init];
      [Colores1 addObject:@"Negro"];
      [Colores1 addObject:@"Marrón"];
      [Colores1 addObject:@"Rojo"];
      [Colores1 addObject:@"Naranja"];
      [Colores1 addObject:@"Amarillo"];
      [Colores1 addObject:@"Verde"];
      [Colores1 addObject:@"Azul"];
      [Colores1 addObject:@"Violeta"];
      [Colores1 addObject:@"Gris"];
      [Colores1 addObject:@"Blanco"];
  
      Colores2 = [[NSMutableArray alloc] init];
      [Colores2 addObject:@"Negro"];
      [Colores2 addObject:@"Marrón"];
      [Colores2 addObject:@"Rojo"];
      [Colores2 addObject:@"Naranja"];
      [Colores2 addObject:@"Amarillo"];
      [Colores2 addObject:@"Verde"];
      [Colores2 addObject:@"Azul"];
      [Colores2 addObject:@"Violeta"];
      [Colores2 addObject:@"Gris"];
      [Colores2 addObject:@"Blanco"];
  
      Colores3 = [[NSMutableArray alloc] init];
