Rookie Help With Undeclared Variables_XCode

Question

Hello, I am having trouble with xcode and I am using the IPhone for Dummies as a training guide. I am totally brand new at any programing. I am getting the same errors that indicate undeclared variable in two places. Below is a copy of the program code. The first one is "savedNumberforKey" in the line below the 2nd commented out line begining with //jm. The next is the same error on the line below the "- (void) applicationWillTerminate. Thanks for your patience and any assistance.

import "ReturnMeToAppDelegate.h"

import "ReturnMeToViewController.h"

NSString *kNumberLocationKey = @"NumberLocation";

@implementation ReturnMeToAppDelegate

@synthesize window; @synthesize viewController; @synthesize savedNumber;

pragma mark - UIApplicationDelegate methods

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

  NSString *tempString = [[NSUserDefaults standardUserDefaults]objectForKey:kNumberLocationKey];

//jm self.savedNumber = [[NSUserDefaults standardUserDefaults]objectForKey:kNumberLocationKey]; self.savedNumber = tempString; [tempString release]; if (savedNumber == nil) { NSString *aString = @"517 423 6192"; savedNumber = aString; [aString release]; //jm savedNumber = @"517 423 6192"; NSDictionary *savedNumberDict = [NSDictionary dictionaryWithObject:savedNumberforKey:kNumberLocationKey]; [[NSUserDefaults standardUserDefaults] registerDefaults:savedNumberDict ]; }

[window addSubview:viewController.view]; [window makeKeyAndVisible]; }

• (void)applicationWillTerminate:(UIApplication *)application {

  [[NSUserDefaults standardUserDefaults] setObject:savedNumberforKey:kNumberLocationKey]; }

  // Override point for customization after app launch

• (void)dealloc { [viewController release]; [window release]; [savedNumber release]; [kNumberLocationKey release];

  [super dealloc]; }
