after experimenting fabric sdk, successful in integration. came along conclusions, , want share guys.
1) when first time login twitter successfully, session of twtrsession has been created user. lasts after close app , reopen it.
2) if session has been created you, , try login getting session object without logging out, authentication error returned.
3) can check if session exists or not using:
if([[twitter sharedinstance] session]) { nslog(@"session present!!!"); nslog(@"signed in %@", [[[twitter sharedinstance] session] username]); } else { nslog(@"you need login!!"); } 4) recommend login using
[[twitter sharedinstance] loginwithcompletion:^(twtrsession *session, nserror *error)];
instead of:
[twtrloginbutton buttonwithlogincompletion:^(twtrsession *session, nserror *error)];
use twitter's login button only, when sure no session exists currently.
5) if twitter's authentication teasing up, uninstall app , try fresh install. this last solution!
6) logout session, use [[twitter sharedinstance] logout];
coding part:
i assuming have followed steps fabric mac app.
first login user, make timeline request.
-(void) loginusertotwitter { if([[twitter sharedinstance] session]) { nslog(@"session present!!!"); nslog(@"signed in %@", [[[twitter sharedinstance] session] username]); [self getusertimeline]; } else { nslog(@"session not found. make new request!"); [[twitter sharedinstance] loginwithcompletion:^(twtrsession *session, nserror *error) { if(error) nslog(@"error occurred... %@",error.localizeddescription); else { nslog(@"successfully logged in session :%@",session); [self getusertimeline]; } }]; } } -(void) getusertimeline { nsurlrequest *request = [[[twitter sharedinstance] apiclient] urlrequestwithmethod:@"get" url:@"https://api.twitter.com/1.1/statuses/user_timeline.json" parameters:@{@"userid": [twitter sharedinstance].session.userid, @"count" : @"5", @"screen_name" : [twitter sharedinstance].session.username} error:nil]; nsurlresponse *response; nserror *error; nsdata *data = [nsurlconnection sendsynchronousrequest:request returningresponse:&response error:&error]; if(!data) { nslog(@"error....: %@",error.localizeddescription); } else { nsstring *string = [[nsstring alloc] initwithdata:data encoding:nsutf8stringencoding]; nslog(@"%@",string); [twitterresponse removeallobjects]; nsarray *arrayrep = [nsjsonserialization jsonobjectwithdata:data options:nsjsonreadingmutableleaves error:nil]; twitterresponse = [nsmutablearray arraywitharray:[twtrtweet tweetswithjsonarray:arrayrep]]; [_tableview reloaddata]; } } i prefer twitter sdk's method extract tweets using [twtrtweet tweetswithjsonarray:arrayrep] instead of restkit. things easy handle here.
display tweets in twitter's standard style:
- (void)viewdidload { [super viewdidload]; // additional setup after loading view, typically nib. // setup tableview self.tableview.estimatedrowheight = 150; self.tableview.rowheight = uitableviewautomaticdimension; // explicitly set on ios 8 if using automatic row height calculation self.tableview.allowsselection = no; [self.tableview registerclass:[twtrtweettableviewcell class] forcellreuseidentifier:@"tweetcell"]; } #pragma mark - tableview methods - (nsinteger)numberofsectionsintableview:(uitableview *)tableview { return 1; } - (nsinteger)tableview:(uitableview *)tableview numberofrowsinsection:(nsinteger)section { return twitterresponse.count; } - (uitableviewcell *)tableview:(uitableview *)tableview cellforrowatindexpath:(nsindexpath *)indexpath { static nsstring *cellid = @"tweetcell"; twtrtweettableviewcell *cell = [tableview dequeuereusablecellwithidentifier:cellid forindexpath:indexpath]; twtrtweet *tweet = twitterresponse[indexpath.row]; [cell configurewithtweet:tweet]; return cell; } // calculate height of each row. must implement - (cgfloat)tableview:(uitableview *)tableview heightforrowatindexpath:(nsindexpath *)indexpath { twtrtweet *tweet = twitterresponse[indexpath.row]; return [twtrtweettableviewcell heightfortweet:tweet width:cgrectgetwidth(self.view.bounds)]; } note:
download fabric sdk here. have enter email address. email link download, have follow steps. fabric mac app have configure xcode project.
hope helps!
