-(IBAction)_clickevernotelogin:(id)sender
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
// Keep this key private
NSString *consumerKey = [[[NSString alloc]

[alertDone release];
return;

}
my logout looks like this

my evernote singlton class which share the instance look like this
here i am passing the nsuerdefault value to change the authentication information to this class
- (void) connect {
if (authToken == nil)

if (!versionOk) {
// Alerting the user that the note was created
UIAlertView *alertDone = [[UIAlertView alloc] initWithTitle: #"Evernote" message: #"Incompatible EDAM client protocol version" delegate: self cancelButtonTitle: #"Ok" otherButtonTitles: nil];
[alertDone show];
[alertDone release];
return;
}
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[[NSNotificationCenter defaultCenter] addObserver:self selector:#selector(evrloginnotif:) name:#"evrloginnotiff" object:nil];
//Checks if there is a saved User Name
NSError *error = nil;
if([defaults objectForKey:#"usernameever"]&&[defaults objectForKey:#"passwrdevernote"])
{
username = [defaults objectForKey:#"usernameever"];
password = [defaults objectForKey:#"passwrdevernote"];
//BOOL flag = [SFHFKeychainUtils storeUsername:username andPassword:password forServiceName:#"mybibleappever" updateExisting:TRUE error:&error];
// Returned result from the Evernote servers after authentication
EDAMAuthenticationResult* authResult =[userStore authenticate:username :password : consumerKey :consumerSecret];
// User object describing the account
self.user = [authResult user];
// We are going to save the authentication token
self.authToken = [authResult authenticationToken];
// and the shard id
self.shardId = [user shardId];
// Creating the user's noteStore's URL
noteStoreUri = [[[NSURL alloc] initWithString:[NSString stringWithFormat:#"%#%#", noteStoreUriBase, shardId] ] autorelease];
// Creating the User-Agent
UIDevice *device = [UIDevice currentDevice];
NSString * userAgent = [NSString stringWithFormat:#"%#/%#;%#(%#)/%#", applicationName,applicationVersion, [device systemName], [device model], [device systemVersion]];
// Initializing the NoteStore client

noteStore = [[[EDAMNoteStoreClient alloc] initWithProtocol:noteStoreProtocol] retain];
}
}
}
how to solve this bug,,thanks
EDIT
but when i rebuild the app,i am getting the correct notes from the username

Answer 1

NSUserDefaults *Test = [NSUserDefaults standardUserDefaults];
[Test removeObjectForKey:#"usernameevernote"];
[Test removeObjectForKey:#"passwrdevernote"];
[Test removeObjectForKey:#"usernameevernotetocken"];
[Test removeObjectForKey:#"usernameever"];
[Test synchronize];
maybe you should have remove objects and synchronize it again so it will remove all objects.

Answer 2

Add "[[NSUserDefaults standardUserDefaults] synchronize];" line everywhere you set value or remove key from NSUserDefault.
May be synchronization is the problem.
