best way to implement twitter - ios

Question

1) I have found the Twitter rush sample code from this link Twitter with OAuth
for the integration.
I have added consumer key and secret key. But it never authorizes the app.
2) And if I use share kit it gives the error that there was a problem requesting access from twitter.
3) If I use social framework then it will give alert if user hasn't added his/her account in settings.
I need that user shouldn't go outside the app for twitter login.
Does anyone have any idea on what would be the best way to integrate with twitter?
Please help.

I Hope This will help you . . .
1.Add following classes to your project
GTMOAuthAuthentication.h/m
GTMOAuthSignIn.h/m
GTMHTTPFetcher.h/m
GTMOAuthViewControllerTouch.h/m
GTMOAuthViewTouch.xib
2 . Add following frameworks
Security.framework and SystemConfiguration.framework.
3 .set -ObjC build option for the application target's "Other Linker Flags".
4 . Then it's time for some coding .
import GTMOAuthAuthentication.h and GTMOAuthViewControllerTouch.h
- (void)signInWithTwitter
{
NSURL *requestURL = [NSURL URLWithString:#"https://api.twitter.com/oauth/request_token"];
NSURL *accessURL = [NSURL URLWithString:#"https://api.twitter.com/oauth/access_token"];
NSURL *authorizeURL = [NSURL URLWithString:#"https://api.twitter.com/oauth/authorize"];
NSString *scope = #"http://api.twitter.com/";
GTMOAuthAuthentication *auth = [self authForTwitter];
[auth setCallback:#"http://www.noop.com/OAuthCallback"];
GTMOAuthViewControllerTouch *viewController;
viewController = [[GTMOAuthViewControllerTouch alloc] initWithScope:scope
language:nil
requestTokenURL:requestURL
authorizeTokenURL:authorizeURL
accessTokenURL:accessURL
authentication:auth
appServiceName:#"AppName : Twitter"
delegate:self
finishedSelector:#selector(viewController:finishedWithAuth:error:)];
[appDelegate.navigationController pushViewController:viewController animated:YES];
}
- (GTMOAuthAuthentication *)authForTwitter {
GTMOAuthAuthentication *auth = [[GTMOAuthAuthentication alloc] initWithSignatureMethod:kGTMOAuthSignatureMethodHMAC_SHA1
consumerKey:TWITTER_CONSUMER_KEY
privateKey:TWITTER_CONSUMER_SECRET];
[auth setServiceProvider:#"Twitter"];
return auth;
}
- (void)viewController:(GTMOAuthViewControllerTouch *)viewController finishedWithAuth:(GTMOAuthAuthentication *)auth error:(NSError *)error {
if(error)
{
//handle error
}
else
{
// do stuff as per your app.
}
}
NOte : if you get error message like "failed to validate oauth signature and token" then check you system time is correct or not .

If you want that user shouldn't go outside you can use ACAccountStore Account.Framework and Social.framework for iOS 6,
NSUrl *url = [NSURL URLWithString:#"https://api.twitter.com/1.1/users/show.json"];
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys:twittername,#"screen_name",nil];
account = [[ACAccountStore alloc] init];
ACAccountType *twitterAccountType = [account accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter];
NSArray *twitterAccounts = [account accountsWithAccountType:twitterAccountType];
// Runing on iOS 6
if (NSClassFromString(#"SLComposeViewController") && [SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter])
{
[account requestAccessToAccountsWithType:twitterAccountType options:NULL completion:^(BOOL granted, NSError *error)
{
if (granted)
{
SLRequest *request = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodGET URL:url parameters:params];
[request setAccount:[twitterAccounts lastObject]];
dispatch_async(dispatch_get_main_queue(), ^
{
[NSURLConnection sendAsynchronousRequest:request.preparedURLRequest queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response1, NSData *data, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^
{
if (data)
{
// [self loadData:data];
NSString* newStr = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding] ;
NSLog(#"data:%#",newStr);
}
});
}];
});
}
}];
}
else if (NSClassFromString(#"TWTweetComposeViewController") && [TWTweetComposeViewController canSendTweet]) // Runing on iOS 5
{
[account requestAccessToAccountsWithType:twitterAccountType withCompletionHandler:^(BOOL granted, NSError *error)
{
if (granted)
{
TWRequest *request = [[TWRequest alloc] initWithURL:url parameters:params requestMethod:TWRequestMethodGET];
[request setAccount:[twitterAccounts lastObject]];
dispatch_async(dispatch_get_main_queue(), ^
{
[NSURLConnection sendAsynchronousRequest:request.signedURLRequest queue:[[NSOperationQueue alloc] init] completionHandler:^(NSURLResponse *response1, NSData *data, NSError *error)
{
dispatch_async(dispatch_get_main_queue(), ^
{
if (data)
{
NSString* newStr = [[NSString alloc] initWithData:data
encoding:NSUTF8StringEncoding];
NSLog(#"data:%#",newStr); }
});
}];
});
}
}];
}
}
You have to retain ACAccountStore: in .h
#property (nonatomic, strong) ACAccountStore *account;
