title: Setting a property in PrepareForSegue is null for ViewDidLoad but correct later on
body: <p>I have searched up and down on this and found a few that were similar but not my exact problem. In my detail view controller I have a segue that opens a popover table view controller. In the PrepareForSegue method, I set a property of the table view, like so:</p>
  
  <pre><code>- (void)prepareForSegue:(UIStoryboardSegue *)segue sender:(id)sender
  {
      if ([[segue identifier] isEqualToString:@"StateSegue"])
      {
          popover = [(UIStoryboardPopoverSegue *)segue popoverController];
          StatePickerController *statePicker = (StatePickerController *)popover.contentViewController;
          statePicker.delegate = self;
          statePicker.pickerType = @"states";
      }
  }
  </code></pre>
  
  <p>I pass both the delegate and the pickerType value. In my table view, StatePickerController, in the header I declared these properties like this:</p>
  
  <pre><code>@property (nonatomic,assign) id&lt;StatePickerDelegate&gt; delegate;
  @property (nonatomic,strong) NSString *pickerType;
  </code></pre>
  
  <p>I know these values are getting passed into my popover controller correctly because later on in didSelectRowAtIndexPath I can reference them both and I get the right delegate and "state", however in the viewDidLoad method, both are still (null).</p>
  
  <pre><code>- (void)viewDidLoad
  {
      [super viewDidLoad];
      self.clearsSelectionOnViewWillAppear = NO;
      self.contentSizeForViewInPopover = CGSizeMake(150.0, 140.0);
      self.states = [NSMutableArray array];
      NSLog(@"%@",self.delegate); //returns (null)
      NSLog(@"%@",self.pickerType); //returns (null)
  }
  
  - (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
  {
      NSLog(@"%@",self.pickerType); //corectly logs "state"
      NSString *state = [_states objectAtIndex:indexPath.row];
      [self.delegate stateSelected:state]; //correctly runs method on detailviewcontroller
  }
  </code></pre>
  
  <p>Is there some point after the viewDidLoad method where these properties get set? I need access to these values right when the view loads because I need to determine what data populates in the table based on what is passed from the detailviewcontroller.</p>
