無法發佈來自另一個ViewController的推文

Question

我使用Outh將Twitter添加到我的應用程序。

下面是分別用於登錄和發佈推文的兩個UIViewController。

1.SettingViewcontroller 2.DetailViewcontroller

此代碼爲登錄與SettingViewcontroller嘰嘰喳喳。

- (void)switchAction1:(UISwitch*)sender 
    { 
    if (sender.on) 
    { 
      if(_engine) 
     return; 

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

    UIViewController *controller =[SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _engine delegate: self]; 

    DetailViewcontroller *detobj=[[DetailViewcontroller alloc]init]; 

detobj.detail_enginne=_engine; 

    [detobj release]; 

    [self presentModalViewController: controller animated: YES]; 
    } 
    if(!sender.on) 
    { 

NSLog(@"Logout section"); 

    } 
} 

而在詳細查看控制器動作表按鈕cliked時下面的代碼會執行。

if ([detail_enginne isAuthorized]) 
    { 
     NSLog(@"engine availble"); 

       NSString *str=@"hai twitterrrrrrrrrrr"; 

      [detail_enginne sendUpdate:str]; 

    } 
    else{ 
     NSLog(@"Engine not availabele"); 
      } 
} 

這裏Iam無法發送來自DetailViewcontroller的推文。

如何實現這個？

更新使用viewDidLoad中不筆尖

蔭裝載儀詳細視圖。

Detailview.m

這是從的DetailView數據發佈到Facebook和Twitter

-(void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex { 

    // For facebook 
if(buttonIndex == 0) 
{ 


    if ([session resume]) { 


     [self postToWall]; 

     NSLog(@"Post to wall"); 

    } 
    else { 

     self.loginDialog = nil; 
     _loginDialog = [[FBLoginDialog alloc] init];  
     [_loginDialog show]; 

    } 


}       

// For twittter 
    if(buttonIndex == 1) 
    {   
    if(detail_enginne!=nil) 
    { 

     NSString *str=@" hai twitter "; 
     [detail_enginne sendUpdate:str]; 

    } 
    else 
    { 
     NSLog(@"Not availabele"); 

    } 
} 
if(buttonIndex == 2) 
{ 

    NSLog(@"cancel button "); 


} 
    } 

Answer 1

第一件事情是，你越來越的用戶憑據actionSheet方法？

我不知道，你是什麼目的檢查你的按鈕索引。 你試試這樣也，

if ([detail_enginne isAuthorized]) 
{ 
    NSLog(@"engine availble"); 
    NSString *str=@"hai twitterrrrrrrrrrr"; 
    [detail_enginne sendUpdate:str]; 
} 
else 
{ 
    NSLog(@"Engine not availabele"); 
} 

從您的代碼，

- (void)switchAction1:(UISwitch*)sender 
     { 
     if (sender.on) 
     { 
       if(_engine) 
      return; 

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

     UIViewController *controller =[SA_OAuthTwitterController controllerToEnterCredentialsWithTwitterEngine: _engine delegate: self]; 
    if(controller) 
{ 
    [self presentModalViewController: controller animated: YES]; //Here You will show your login screen twitter 
} 


//After getting credentials , You do this 

    DetailViewcontroller *detobj=[[DetailViewcontroller alloc]init]; 

    detobj.detail_enginne=_engine; // this **detobj** should be used for presenting detailView 

     [detobj release]; 
     } 
     if(!sender.on) 
     { 

    NSLog(@"Logout section"); 

     } 
    }
