Can't see HighScore if i relaunch my application - xcode

Question

I'm having problems with my HighScore. I can see my HighScore in the HighScore label when i'm finished running the app, but when i quit my application and relaunch it, the HighScore disappears... Can somebody tell me what's wrong?
Here is my .h file:
#import <UIKit/UIKit.h>
#import <AudioToolbox/AudioToolbox.h>
int Y;
BOOL Start;
BOOL applications;
int RandomPosition;
int Scorenumber;
int HighScore;
#interface ViewController : UIViewController
{
SystemSoundID SoundId;
IBOutlet UILabel *Intro1;
IBOutlet UILabel *Intro2;
IBOutlet UILabel *Intro3;
IBOutlet UIImageView *Heli;
NSTimer *timer;
IBOutlet UIImageView *Obstacle;
IBOutlet UIImageView *Obstacle2;
IBOutlet UIImageView *Obstacle3;
IBOutlet UIImageView *Obstacle4;
IBOutlet UIImageView *Obstacle5;
IBOutlet UIImageView *Obstacle6;
IBOutlet UIImageView *Obstacle7;
IBOutlet UIImageView *Obstacle8;
IBOutlet UIImageView *Obstacle9;
IBOutlet UIImageView *Bottom1;
IBOutlet UIImageView *Bottom2;
IBOutlet UIImageView *Top2;
IBOutlet UIImageView *Top1;
IBOutlet UIImageView *corona;
IBOutlet UILabel *Score;
NSTimer *Scorer;
}
#end
And here is my .m file:
#import "ViewController.h"
#interface ViewController ()
#end
#implementation ViewController

It would really be helpful if someone could answer this :)
I'm kinda tired of this after sitting with it for HOURS!

Answer 1

Your putting your high score into NSUserDefaults with the key:
forKey:#"HighScoreSaved"];
But you are trying to pull it out with:
objectForKey:#"HighScore"]
Your key needs to be the same in both places. Or in other words, you have to write to, and read from NSUserDefaults with the same key.
