title: How to set the text alignment in picker view iOS
body: <p>I need to set the alignment of the text in picker view but my solutions doesn't work.
  This is my code so far. I used array to store values on the picker view.</p>
  
  <pre><code>- (void)viewDidLoad{
  
  [super viewDidLoad];
  
  self.source = [[NSMutableArray alloc]
                 initWithObjects:@"  5   Minutes", @"10   Minutes", @"15   Minutes", @"20   Minutes",@"25   Minutes",@"30   Minutes",@"35   Minutes",@"40   Minutes",@"45   Minutes",@"50   Minutes",@"55   Minutes",@"60   Minutes", nil];
  
  self.picker = [[UIPickerView alloc] initWithFrame:CGRectMake(0.0, 275.0, 320.0, 120.0)];
  
  
  self.picker.delegate = self;
  self.picker.dataSource = self;
  
  [self.view addSubview:self.picker];
  [self.picker selectRow:2 inComponent:0 animated:YES];}
  </code></pre>
  
  <p>then,</p>
  
  <pre><code>- (NSString *)pickerView:(UIPickerView *)pickerView titleForRow:(NSInteger)row forComponent:(NSInteger)component {
  return [source objectAtIndex:row];
  }
  
  - (NSInteger)numberOfComponentsInPickerView:
  (UIPickerView *)pickerView
  {
   return 1;
  }
  
  - (NSInteger)pickerView:(UIPickerView *)pickerView
  numberOfRowsInComponent:(NSInteger)component
  {
  return [source count];
  }
  </code></pre>
  
  <p>However, it works fine when it displays the values. But when I align the text at the center,  instead of displaying the text(values on picker view), the picker view becomes empty. This is the code on how I've done the alignment at the center.</p>
  
  <pre><code>- (UIView *)pickerView:(UIPickerView *)pickerView viewForRow:(NSInteger)row forComponent:(NSInteger)component 
  reusingView:(UIView *)view
  {
  UILabel *label = [[UILabel alloc] initWithFrame:CGRectMake(0, 0, 300, 37)];
   //label.text = [NSString stringWithFormat:@"something here"];
  label.textAlignment = UITextAlignmentCenter;
  label.backgroundColor = [UIColor clearColor];
  return label;
  }
  </code></pre>
  
  <p>What might be the solution for this?
  Please help me regarding this problem. </p>
  
  <p>Thanks.</p>
