How do I keep the data stored in the plist from the UITextField when the application is restarted?

I am using plist to store the data entered into UITextFields. But when the application was restarted, all the data entered earlier was deleted. How to save data to Plist. I have a UITableView and when a cell is touched a view appears with two UITextFields. nameField and descriptionField. I saved the data this way.

My code.

-(void)save:(id)sender
{

    indexOfDataArray = temp;

    NSString *string1 = [[NSString alloc]init];
    NSString *string2 = [[NSString alloc]init];
    string1 = nameField.text;
    string2 = descriptionField.text;
    NSDictionary *myDict = [[NSDictionary alloc] initWithObjectsAndKeys:string2, string1, nil];
    //NSDictionary *myDict = [[NSDictionary alloc] initWithObjectsAndKeys:@"value", string2, @"key", string1, @"index", [NSNumber numberWithInt:indexOfDataArray], nil];

    [myArray addObject:myDict];

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); 
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *path = [documentsDirectory stringByAppendingPathComponent:@"tableVideoData.plist"]; 

    [myArray writeToFile:path atomically:YES];

    UIAlertView *alertMesage = [[UIAlertView alloc] initWithTitle: @"Save Alert" message:@"The data entered is saved" delegate:nil cancelButtonTitle:@"cancel" otherButtonTitles:nil] ;
    [alertMesage show];
    [alertMesage release];
}

      

        
        
        
      

    

The path to the file

/Users/srikanth/Library/Application Support/iPhone Simulator/User/Applications/31DEFEE7-A468-44BD-B044-53BEA3391C1A/Documents

      

        
        
        
      

    

But the problem is that every time I restart the application, the data is created in a new plist file in a new folder. So how can I store data in a single plist?

Thanks.
