UIPicker accessing items from a plist

I have a plist that is being loaded into a UIPickerView. I can access the array info and have it loaded into the picker in one of the co开发者_运维技巧mponents. What I'm trying to do is to access Item 0 or Item 1 and have them displayed on a UILabel based on a condition.

I can't figure out how to access Item 0 or Item 1 (the string values). Any tips on how I'd go about doing this? thanks for the help.

here's an image to clarify what I'm talking about:

pickerViewcontroller.h

#import <UIKit/UIKit.h>
#define kStateComponent 0
#define kZipComponent 1

    @interface PickerViewController : UIViewController
    <UIPickerViewDataSource,UIPickerViewDelegate>{
        IBOutlet UIPickerView *dpicker;
        NSDictionary *stateZip;
        NSArray *states;
        NSArray *zips;

    }
    @property (nonatomic,retain) UIPickerView *dpicker;
    @property (nonatomic,retain) NSDictionary *stateZip;
    @property (nonatomic, retain) NSArray *states;
    @property (nonatomic, retain) NSArray *zips;
    @end

pickerViewcontroller.m

#import "PickerViewController.h"


@implementation PickerViewController
@synthesize dpicker;                  
@synthesize stateZip;
@synthesize states;
@synthesize zips;


-(void) viewDidLoad{

    NSBundle *bundle = [NSBundle mainBundle];

    NSString *plistPath =[bundle pathForResource:@"plistfilename" ofType:@"plist"];

    NSDictionary *dictionary = [[NSDictionary alloc] initWithContentsOfFile:plistPath];
    self.stateZip=dictionary;
    [dictionary release];


    NSArray *component = [self.stateZip allKeys];
    NSArray *sorted =[component sortedArrayUsingSelector:@selector(compare:)];
    self.states=sorted;


            NSString *selectedState = [self.states objectAtIndex:0];
        NSArray *array = [stateZip objectForKey:selectedState];
    self.zips = array;


}
