// Set new credentials.
[_username release];
_username = [newUsername retain];
[_password release];
_password = [newPassword retain];
if ([self clearsCookies]) {
// Remove all cookies for twitter, to ensure next connection uses new credentials.
NSString *urlString = [NSString stringWithFormat:#"%#://%#",
(_secureConnection) ? #"https" : #"http",
_APIDomain];
NSURL *url = [NSURL URLWithString:urlString];
NSHTTPCookieStorage *cookieStorage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
NSEnumerator *enumerator = [[cookieStorage cookiesForURL:url] objectEnumerator];
NSHTTPCookie *cookie = nil;
while (cookie == [enumerator nextObject]) {
[cookieStorage deleteCookie:cookie];
}
}
}
- (NSString *)sendUpdate:(NSString *)status
{
return [self sendUpdate:status inReplyTo:0];
}
- (NSString *)sendUpdate:(NSString *)status inReplyTo:(unsigned long)updateID
{
if (!status) {
return nil;
}
NSString *path = [NSString stringWithFormat:#"statuses/update.%#", API_FORMAT];
NSString *trimmedText = status;
if ([trimmedText length] > MAX_MESSAGE_LENGTH) {
trimmedText = [trimmedText substringToIndex:MAX_MESSAGE_LENGTH];
}
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:0];
[params setObject:trimmedText forKey:#"status"];
if (updateID > 0) {
[params setObject:[NSString stringWithFormat:#"%u", updateID] forKey:#"in_reply_to_status_id"];
}
NSString *body = [self _queryStringWithBase:nil parameters:params prefixed:NO];
return [self _sendRequestWithMethod:HTTP_POST_METHOD path:path
queryParameters:params body:body
requestType:MGTwitterUpdateSendRequest
responseType:MGTwitterStatus];
}
TwitterPostViewController.m
- (IBAction)submitTweet{
[tweet resignFirstResponder];
if([[tweet text] length] > 0){
NSLog(#"%#",[[NSUserDefaults standardUserDefaults] valueForKey:#"TwitterUsername"]);
NSLog(#"%#",[[NSUserDefaults standardUserDefaults] valueForKey:#"TwitterPassword"]);
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:YES];
[engine sendUpdate:[tweet text]];
}
}
- (void)requestFailed:(NSString *)requestIdentifier withError:(NSError *)error{
NSLog(#"Fail: %#", error);
[[UIApplication sharedApplication] setNetworkActivityIndicatorVisible:NO];
UIAlertView *failAlert;
if([error code] == 401){
failAlert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Incorrect Username & Password." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
[failAlert setTag:10];
[failAlert setDelegate:self];
}
else
{
failAlert = [[UIAlertView alloc] initWithTitle:#"Error" message:#"Failed sending status to Twitter." delegate:nil cancelButtonTitle:#"OK" otherButtonTitles:nil];
}
[failAlert show];
[failAlert release];
}
It shows me the fail popup of Incorrect username and password
I have checked through nslog that username and password are going correct.
what could be wrong?

It looks like the version of MGTwitterEngine you're using is trying to use basic auth. That was switched off in Twitter in favour of OAuth. Get a newer version of MGTwitterEngine (or a fork that supports OAuth).
