I'm looking to have a UITextField display a UIPickerView when touched. I found quite a few questions on the same topic that say to use UITextField.inputView. However, when I try, nothing changes.

I have a very simple code:

setupViewController.h

#import <UIKit/UIKit.h>

extern NSString *setupRightChannel;

@interface setupViewController : UIViewController
{
    UITextField* rightChannelField; 
    UIPickerView *channelPicker;
}

@property (retain, nonatomic) IBOutlet UITextField* rightChannelField;
@property (retain, readwrite) IBOutlet UIPickerView *channelPicker;

setupViewController.m

#import "setupViewController.h"

@Interface setupViewController()

@end

@implementation setupViewController

@synthesize rightChannelField;

- (id)initWithNibName:(NSString *)nibNameOrNil bundle:(NSBundle *)nibBundleOrNil
{
    self = [super initWithNibName:nibNameOrNil bundle:nibBundleOrNil];
    if (self) {
        // Custom initialization

    }
    return self;
}


- (void)viewDidLoad
{
    [super viewDidLoad];
    self.navigationItem.title = @"Setup";
    // Do any additional setup after loading the view from its nib.
    rightChannelField.inputView = channelPicker;
}

-(IBAction)okClicked:(id)sender
{
    setupRightChannel = rightChannelField.text;
}

I feel like I might be missing something fundamental here, but I honestly cannot think of what it is.
