将Twitter集成到iPhone应用程序 [英] Integrate twitter to IPhone application

问题描述

我希望将Twitter集成到我的应用程序中.我的项目是在ARC支持下创建的.当我添加Twitter框架时，我还用-fno-objc-arc标记了.m文件.

I am hoping to integrate Twitter to my application. My project is created with ARC support. When i added the Twitter framework i also flagged the .m files with -fno-objc-arc.

我可以登录到twitter(这意味着身份验证过程可以正常工作)，并且在身份验证之后，当我单击tweet按钮时，应用程序崩溃了.

I could login to twitter (meaning, the authentication process works), and after the authentication that application crashes when i click the tweet button.

1.)首先，这就是Twitter身份验证的工作原理.

1.) This is what gets called first, twitter authentication works fine.

-(void)loginTwitterUser{
    if(_engine) return;


    _engine = [[SA_OAuthTwitterEngine alloc] initOAuthWithDelegate:self];  
    _engine.consumerKey = @"xxxxxx";
    _engine.consumerSecret = @"xxxxxx";

    if (![_engine isAuthorized]) {
        UIViewController *controller = [SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine:_engine delegate:self];
        if (controller) {
            [self presentModalViewController:controller animated:YES];
        }

    }

• _engine-我已声明这是.h文件，但未在.m

  • _engine - i have declared this is the .h file, but did not synthesize it in the .m

    1. 这是我们要发布的地方

    1. This is where we are going to tweet

    -(void)tweetThis:(id)sender{
    [_engine sendUpdate:@"Tweet something"];
    }
    

  3.)其他脱盐方法

  #pragma mark SA_OAuthTwitterEngineDelegate
  - (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"];
  }
  
  
  #pragma mark TwitterEngineDelegate
  - (void) requestSucceeded: (NSString *) requestIdentifier {
  
      NSLog(@"Request %@ succeeded", requestIdentifier);
  }
  
  - (void) requestFailed: (NSString *) requestIdentifier withError: (NSError *) error {
  
      NSLog(@"Request %@ failed with error: %@", requestIdentifier, error);
  }
  
  #pragma mark SA_OAuthTwitterController Delegate
  

  在NSLog中，username是null.为什么会这样?

  In the NSLog username is null. Why is this ?

  - (void) OAuthTwitterController: (SA_OAuthTwitterController *) controller authenticatedWithUsername: (NSString *) username {
  
      NSLog(@"Authenticated with user %@", username);
  
  }
  
  
  - (void) OAuthTwitterControllerFailed: (SA_OAuthTwitterController *) controller  {
  
      NSLog(@"Authentication Failure");
  }
  
  - (void) OAuthTwitterControllerCanceled: (SA_OAuthTwitterController *) controller {
  
      NSLog(@"Authentication Canceled");
  }
  

  应用程序在MGTwitterEngine.m的return语句中崩溃.

  The application crashes in the MGTwitterEngine.m at the return statement.

  - (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];
  }
  

  我该如何解决?

  推荐答案

  检查您的SA_OAuthTwitterEngine.m并尝试实施以下更改.您应该将http更改为https.

  Check your SA_OAuthTwitterEngine.m and try to implement the changes below. You should change http to https.

  - (SA_OAuthTwitterEngine *) initOAuthWithDelegate: (NSObject *) delegate {
  if (self = (id) [super initWithDelegate: delegate]) 
      {
          self.requestTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/request_token"];
          self.accessTokenURL = [NSURL URLWithString: @"https://twitter.com/oauth/access_token"];
          self.authorizeURL = [NSURL URLWithString: @"https://twitter.com/oauth/authorize"];
      }
      return self;
  }
