Login with Twitter on iOS

How to make Twitter login in iOS APP?

You can use fabric to enable login using Twitter which will enable you a lot more functionalities than authentication like Crashlytics (crash reporting tool)

There are two ways for authentication

1.Log in Button

TWTRLogInButton* logInButton = [TWTRLogInButton buttonWithLogInCompletion:^(TWTRSession* session, NSError* error) {
  if (session) {
      NSLog(@"signed in as %@", [session userName]);
  } else {
      NSLog(@"error: %@", [error localizedDescription]);
  }
}];
logInButton.center = self.view.center;
[self.view addSubview:logInButton];

2. Log in Method

[[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session, NSError *error) {
  if (session) {
      NSLog(@"signed in as %@", [session userName]);
  } else {
      NSLog(@"error: %@", [error localizedDescription]);
  }
}];

Here is the URL for the documentation

iOS twitter login when app is not installed

Add callback URL in this format

twitter-twitterid://

(Replace "twitterid" with "your twitter app id")

Login with twitter always return error

After lot of R&D I got the success. Twitter has made call back url compulsory. I found from this link

You need to add twitterkit-xxxxxxxxxxxxxxxx (twitterkit-consumer key) in call back url at twitter dashboard setting.

I used this method for opening safari (make sure you add safari framework)

TWTRTwitter.sharedInstance().logIn(with: self) { (session, error) in
            if (session != nil) {
                print("signed in as \(session?.userName ?? "")");
            } else {
                print("error: \(error?.localizedDescription ?? "")");
            }
        }

iOS Login with Twitter

You can either use the Twitter account defined by the user in iOS Settings, or register your own Twitter application on https://apps.twitter.com/.

You can use the third-party library STTwitter in both cases.

How to Authorise User login via twitter in ios

You should use Fabric.io as Larcerax is recommending you. When you install it you will be able to login with twitter really easy. I use these methods:

Login:

- (void)loginWithTwitter { 
    [[Twitter sharedInstance] logInWithCompletion:^(TWTRSession *session,
                                              NSError *error) {
    if (session) {
      NSLog(@"signed in as %@", [session userName]);
      [[NXTTwitterManager sharedInstance] requestTwtFollowersWithCursor:nil];
      [[NXTTwitterManager sharedInstance] requestTwtFollowingWithCursor:nil];
    } else {
      NSLog(@"error: %@", [error localizedDescription]);
    }
  }];
}

Get Followers:

- (void)requestTwtFollowersWithCursor:(NSString *)nextCursor {
  NSString *statusesShowEndpoint = [NSString
      stringWithFormat:@"%@%@",
                   @"https://api.twitter.com/1.1/followers/ids.json?",
                   (nextCursor.length > 0)
                       ? [NSString stringWithFormat:@"cursor=%@&count=5000",
                                                    nextCursor]
                       : @"count=5000"];
  NSDictionary *params = @{ @"id" : [Twitter sharedInstance].session.userID };
  NSError *clientError;

  NSURLRequest *request = [[[Twitter sharedInstance] APIClient]
      URLRequestWithMethod:@"GET"
                       URL:statusesShowEndpoint
                parameters:params
                     error:&clientError];

  if (request) {
    [[[Twitter sharedInstance] APIClient]
        sendTwitterRequest:request
                completion:^(NSURLResponse *response, NSData *data,
                         NSError *connectionError) {
                  if (data) {
                    NSError *jsonError;
                    NSDictionary *json =
                        [NSJSONSerialization JSONObjectWithData:data
                                                        options:0
                                                          error:&jsonError];
                    [self.followers addObjectsFromArray:json[@"ids"]];
                    if (![json[@"next_cursor_str"] isEqualToString:@"0"]) {
                      [[NXTTwitterManager sharedInstance]
                          requestTwtFollowersWithCursor:
                              json[@"next_cursor_str"]];
                    } else {
                      [self matchFriends];
                    }
                  } else {
                    NSLog(@"Error: %@", connectionError);
                    [self matchFriends];
                  }
                }];
  } else {
    NSLog(@"Error: %@", clientError);
  }
}

Get Friends (following):

- (void)requestTwtFollowingWithCursor:(NSString *)nextCursor {
  NSString *statusesShowEndpoint = [NSString
          stringWithFormat:@"%@%@",
                   @"https://api.twitter.com/1.1/friends/ids.json?",
                   (nextCursor.length > 0)
                       ? [NSString stringWithFormat:@"cursor=%@&count=5000",
                                                    nextCursor]
                       : @"count=5000"];
  NSDictionary *params = @{ @"id" : [Twitter sharedInstance].session.userID };
  NSError *clientError;

  NSURLRequest *request = [[[Twitter sharedInstance] APIClient]
      URLRequestWithMethod:@"GET"
                       URL:statusesShowEndpoint
                parameters:params
                     error:&clientError];

  if (request) {
    [[[Twitter sharedInstance] APIClient]
        sendTwitterRequest:request
                completion:^(NSURLResponse *response, NSData *data,
                         NSError *connectionError) {
                  if (data) {
                    NSError *jsonError;
                    NSDictionary *json =
                        [NSJSONSerialization JSONObjectWithData:data
                                                        options:0
                                                          error:&jsonError];
                    [self.followings addObjectsFromArray:json[@"ids"]];
                    if (![json[@"next_cursor_str"] isEqualToString:@"0"]) {
                      [[NXTTwitterManager sharedInstance]
                          requestTwtFollowingWithCursor:
                              json[@"next_cursor_str"]];
                    } else {
                      [self matchFriends];
                    }
                  } else {
                    NSLog(@"Error: %@", connectionError);
                    [self matchFriends];
                  }
                }];
  } else {
    NSLog(@"Error: %@", clientError);
  }
}
