iOS版MGTwitterEngine：如何獲取accessToken？錯誤401

我正在使用我的iOS應用的MGTwitterEngine庫發佈推文。iOS版MGTwitterEngine：如何獲取accessToken？錯誤401

NSString *username = dataBase.twiLog; 
NSString *password = dataBase.twiPas;      

NSString *consumerKey = cons_key; 
NSString *consumerSecret = cons_secret; 

// Most API calls require a name and password to be set... 
    if (! username || ! password || !consumerKey || !consumerSecret) { 
     NSLog(@"You forgot to specify your username/password/key/secret in AppController.m, things might not work!"); 
     NSLog(@"And if things are mysteriously working without the username/password, it's because NSURLConnection is using a session cookie from another connection."); 
}  
// Create a TwitterEngine and set our login details. 
MGTwitterEngine *twitterEngine = [[MGTwitterEngine alloc] initWithDelegate:self]; 
twitterEngine setClearsCookies:YES];       
[twitterEngine setUsesSecureConnection:NO]; 
[twitterEngine setConsumerKey:consumerKey secret:consumerSecret]; 

[twitterEngine setUsername:username password:password]; 
[twitterEngine sendUpdate: @"This message was sent via myApp for iOS"];

但是我不能發送推文，直到我getToken。這裏輸出：

Request failed for connectionIdentifier = 5E7C9D2E-1467-45EF-B748-CCBF8F211F8D, error = The operation couldn’t be completed. (HTTP error 401.) ({ 
    body = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<hash>\n <error>Could not authenticate you.</error>\n <request>/1/statuses/update.xml</request>\n</hash>\n"; 
    response = "<NSHTTPURLResponse: 0x6e26a10>"; 
})

我該如何使用MGTwitterEngine發送推文？（沒有從dev.twitter.com手動獲取我的訪問令牌，因爲其他用戶也應該能夠從他們自己發送推文）

我有一個類似的問題，經過許多小時的搜索，我找到了解決方案。我的註銷按鈕僅在用戶通過檢查引擎是否被授權登錄時纔會顯示。然後，用戶點擊按鈕後，這是執行的代碼。

- (void)logoutTwitter { 

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

    if (controller){ 
     [self presentModalViewController: controller animated: YES]; 
    } 
} else { 
    [_engine clearAccessToken]; //This is a method called from SA_OAuthTwitterEngine.h

}

'_engine'是什麼類的對象？ 'MGTwitterEngine'類沒有'isAuthorized'和'clearAccessToken'方法 – 2012-03-15 15:12:12

它的一個'SA_OAuthTwitterEngine'的實例。該類將OAuth引入「MGTwitterEngine」（非OAuth分支） – 2012-06-27 01:36:01
