.Plist Key Value into Label

[teeeroy]

Hey I'm trying to make a joke shuffler app but can't the simple part of my code correct. Here it is...

#import "JokesAppDelegate.h"

@implementation JokesAppDelegate

- (void)readPlist
{
	NSString *dataPath = [[NSBundle mainBundle] pathForResource:@"Jokes" ofType:@"plist"];
    self.data = [NSArray arrayWithContentsOfFile:dataPath];	
	
	NSMutableDictionary *plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:dataPath];
	
	value = [plistDict objectForKey:@"test"];
	
	/* You could now call the string "value" from somewhere to return the value of the string in the .plist specified, for the specified key. */
}


@synthesize window;
@synthesize tabBarController;
@synthesize value;



- (void)applicationDidFinishLaunching:(UIApplication *)application {
	label.text = value;

And Here's the header

#import <UIKit/UIKit.h>


@interface JokesAppDelegate : NSObject <UIApplicationDelegate, UITabBarControllerDelegate> {
    UIWindow *window;
    UITabBarController *tabBarController;
	IBOutlet UILabel *label;
	NSString *value;
	NSArray *data;
	}

@property (nonatomic, retain)	NSString	*value;
@property (nonatomic, retain) NSArray *data;
@property (nonatomic, retain) IBOutlet UIWindow *window;
@property (nonatomic, retain) IBOutlet UITabBarController *tabBarController;

@end

Above, I am trying to find the key "test" in my jokes.plist and get it's value to be displayed in the label but nothing is showing up on the label when I Build and Go.

P.S. As obvious from above I am using a tabbarcontroller

Pls Help

You've got everything right except that you're not setting the label's text in the readplist method. Simply move this code:

label.text = value;

from the applicationDidFinishLaunching method into the readplist method. It should look like this:

#import "JokesAppDelegate.h"

@implementation JokesAppDelegate

- (void)readPlist
{
	NSString *dataPath = [[NSBundle mainBundle] pathForResource:@"Jokes" ofType:@"plist"];
    self.data = [NSArray arrayWithContentsOfFile:dataPath];	
	
	NSMutableDictionary *plistDict = [[NSMutableDictionary alloc] initWithContentsOfFile:dataPath];
	
	value = [plistDict objectForKey:@"test"];
	
        label.text = value;

	/* You could now call the string "value" from somewhere to return the value of the string in the .plist specified, for the specified key. */
}


@synthesize window;
@synthesize tabBarController;
@synthesize value;



- (void)applicationDidFinishLaunching:(UIApplication *)application {
