NSUserDefaults not getting stored string value - iphone

Question

I have UIWebView for reading content. After that i select some text from content stores in string using NSUserDefaults in Viewcontroller. Then i retrieve this string value and displays in UITextView to viewcontroller1. But the UITextView is not updating text from viewcontroller. The NSUserDefaults also not getting updating text. Im using [self.navigationController pushViewController:viewcontroller1 animated:YES]; for switch to viewcontroller1.
viewcontroller:
[wbCont loadHTMLString:webString baseURL:nil];
[self.view addSubview:wbCont];
NSMutableArray *items = [[[UIMenuController sharedMenuController] menuItems] mutableCopy];
if (!items) items = [[NSMutableArray alloc] init];
UIMenuItem *menuItem;
menuItem = [[UIMenuItem alloc] initWithTitle:#"BookMark" action:#selector(save:)];
[items addObject:menuItem];
[menuItem release];
menuItem = [[UIMenuItem alloc] initWithTitle:#"Note" action:#selector(note:)];
[items addObject:menuItem];
[menuItem release];
[[UIMenuController sharedMenuController] setMenuItems:items];
[items release];
- (BOOL) canPerformAction:(SEL)action withSender:(id)sender
{
if (action == #selector(save:))
{
return YES;
}
else if (action == #selector(note:))
{
return YES;
}
else if (action == #selector(copy:))
{
return NO;
}
return [super canPerformAction:action withSender:sender];
}
-(void)save:(id)sender{
NSString *selection = [wbCont stringByEvaluatingJavaScriptFromString:#"window.getSelection().toString()"];
NSLog(#"selection is %#",selection);
NSUserDefaults *userData1 = [NSUserDefaults standardUserDefaults];
[userData1 setObject:selection forKey:#"preferenceName"];
[userData1 synchronize];
[self.navigationController pushViewController:note animated:YES];
}
viewcontroller1:
textView = [[UITextView alloc]initWithFrame:CGRectMake(0,0,320,400)];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
// getting an NSString
NSString *savedValue = [prefs stringForKey:#"preferenceName"];
NSLog(#"saved is %#", savedValue);
textView.text = [NSString stringWithFormat:#"%#", savedValue];

Answer 1

Allocation of textView is in viewDidLoad.
Updating of textView is in viewWillAppear.
-(void) viewWillAppear:(BOOL)animated
[super viewWillAppear:animated];
NSUserDefaults *prefs = [NSUserDefaults standardUserDefaults];
// getting an NSString
NSString *savedValue = [prefs stringForKey:#"preferenceName"];
NSLog(#"saved is %#", savedValue);
textView.text = [NSString stringWithFormat:#"%#", savedValue];
}

I was checked your code just change NSSTring to NSString like below it will working.
-(void)save:(id)sender{
// NSSTring *selection = [wbCont stringByEvaluatingJavaScriptFromString:#"window.getSelection().toString()"];
NSString *selection = [wbCont stringByEvaluatingJavaScriptFromString:#"window.getSelection().toString()"];
NSLog(#"selection is %#",selection);
NSUserDefaults *userData1 = [NSUserDefaults standardUserDefaults];
[userData1 setObject:selection forKey:#"preferenceName"];
[userData1 synchronize];
[self.navigationController pushViewController:note animated:YES];
}
