Save to where? If you want to save to the device you can use NSUserDefaults.

In that case as I said, NSUserDefaults should work just fine.

How to save text depends on your situation. NSUserDefaults is designed to hold small data like settings. If you need to save a whole text then you should use "writeToFile:" to store it in the TMP or an own cache folder.

        // Save
	NSString *someText = @"Bla bla bla bla :P";
	[[NSUserDefaults standardUserDefaults] setObject:someText forKey:@"MyTextIsHere"];
	 
	// Load
	NSString *mySavedString = [[NSUserDefaults standardUserDefaults] objectForKey:@"MyTextIsHere"];
	NSLog(@"%@", mySavedString);

Super easy

Try the Search functionality on the forum. If you've searched for NSUserDefaults you would have gotten plenty of examples.

I wouldn't use NSUserDefaults for saving large amounts of text. Like Gi-lo mentioned, writing to a file would work.

Never tried to write a large string so I don't know what the downside is, if any. NSString has methods for reading from and saving to a file so that solution is trivial too.

added done save button in naviagtion bar right . .Text i can able to see in console uisng nslog in saveAction method , but i am not getting my current folder for savedText.text file. how to check my file. Same time i need to restore my text data in my notes , please guide me

- (void)viewDidLoad
{
[super viewDidLoad];
self.navigationItem.title = @"Notes";

// the nav bar's custom Done button right view
UIBarButtonItem *addButton = [[[UIBarButtonItem alloc] initWithTitle:@"Done"
style:UIBarButtonItemStyleBordered
target:self
action:@selector(saveAction] autorelease];

self.navigationItem.rightBarButtonItem = addButton;

// finish typing text/dismiss the keyboard by removing it as the first responder
//
[self.textview resignFirstResponder];
//self.navigationItem.rightBarButtonItem = nil; // this will remove the "save" button

NSArray *documentPaths = NSSearchPathForDirectoriesInDomains(NSDocumentDire ctory, NSUserDomainMask, YES);
NSString *documentsDirectory = [documentPaths objectAtIndex:0];
NSString *documentTXTPath = [documentsDirectory stringByAppendingPathComponent:@"savedText.txt"];
NSString *savedString = textview.text;

NSLog(@"The Save file is:%@", savedString);

[savedString writeToFile:documentTXTPath atomically:YES];
}
