Mgtwitter engine Login And logOut

Hello I am using MGTwitterEngine to create twitter app.I created different views for followers list, user time line and so on... Once I login It will save user credentials with following code

- (void) storeCachedTwitterOAuthData: (NSString *) data forUsername: (NSString *) username {
    NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
    [defaults setObject: data forKey: @"authData"];
    [defaults synchronize];
}

- (NSString *) cachedTwitterOAuthDataForUsername: (NSString *) username 
{
    return [[NSUserDefaults standardUserDefaults] objectForKey: @"authData"];
}

And I am passing consumer key and secret in view did appear . My question is should I write this consumer key and t开发者_开发问答his user credential code in all view.. or I can do it some other way? And how to logout from twitter?

you should delete cookies for log out thing..

like this..

NSHTTPCookie *cookie;
NSHTTPCookieStorage *storage = [NSHTTPCookieStorage sharedHTTPCookieStorage];
for (cookie in [storage cookies])
{
    NSString* domainName = [cookie domain];
    NSRange domainRange = [domainName rangeOfString:@"twitter"];
    if(domainRange.length > 0)
    {
        [storage deleteCookie:cookie];
    }

}

1. I define consumer secret and key as a constant, they are static, so I just have to import a header, or even better put them in a constants.h and import with the prefix file in all files.

2. Logging out:

   • Logout using MGTwitterEngine ?
   • how to logout from Twitter in iPhone.I am using OAuth+MGTwitterEngine Library, there is a clearAccessToken method in the engine class.
