從我的iOS 5應用程序打開Twitter應用程序

Question

我想從iOS 5中的應用程序中打開Twitter應用程序，但它不會打開。任何幫助將不勝感激，我已經包括我在下面使用的代碼。

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs:root=TWITTER"]]; 

請幫助我，並提前致謝！

你想推出Twitter應用程序，還是隻發送你的應用程序內的推文？我相信您上面顯示的代碼是在您的設置應用中啓動Twitters偏好設置......我也相信已被禁止使用5.1

如果您希望將Twitter集成添加到您的應用中Apple提供了很好的示例代碼向你展示如何在iOS 5中使用推特內置的Twitter框架使用Twitter。

現在我建議你下載這個示例代碼，看看還有什麼需要發送推文（如檢查CanTweetStatus），但我附加如何在這篇文章中發送推文的基本思路。

https://developer.apple.com/library/ios/#samplecode/Tweeting/Introduction/Intro.html#//apple_ref/doc/uid/DTS40011191

- (IBAction)sendCustomTweet:(id)sender { 
    // Create an account store object. 
    ACAccountStore *accountStore = [[ACAccountStore alloc] init]; 

    // Create an account type that ensures Twitter accounts are retrieved. 
    ACAccountType *accountType = [accountStore accountTypeWithAccountTypeIdentifier:ACAccountTypeIdentifierTwitter]; 

    // Request access from the user to use their Twitter accounts. 
    [accountStore requestAccessToAccountsWithType:accountType withCompletionHandler:^(BOOL granted, NSError *error) { 
     if(granted) { 
      // Get the list of Twitter accounts. 
      NSArray *accountsArray = [accountStore accountsWithAccountType:accountType]; 

      // For the sake of brevity, we'll assume there is only one Twitter account present. 
      // You would ideally ask the user which account they want to tweet from, if there is more than one Twitter account present. 
      if ([accountsArray count] > 0) { 
       // Grab the initial Twitter account to tweet from. 
       ACAccount *twitterAccount = [accountsArray objectAtIndex:0]; 

       // Create a request, which in this example, posts a tweet to the user's timeline. 
       // This example uses version 1 of the Twitter API. 
       // This may need to be changed to whichever version is currently appropriate. 
       TWRequest *postRequest = [[TWRequest alloc] initWithURL:[NSURL URLWithString:@"http://api.twitter.com/1/statuses/update.json"] parameters:[NSDictionary dictionaryWithObject:@"Hello. This is a tweet." forKey:@"status"] requestMethod:TWRequestMethodPOST]; 

       // Set the account used to post the tweet. 
       [postRequest setAccount:twitterAccount]; 

       // Perform the request created above and create a handler block to handle the response. 
       [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { 
        NSString *output = [NSString stringWithFormat:@"HTTP response status: %i", [urlResponse statusCode]]; 
        [self performSelectorOnMainThread:@selector(displayText:) withObject:output waitUntilDone:NO]; 
       }]; 
      } 
     } 
    }]; 
} 

祝您好運！

如果你只是試圖打開實際的Twitter的應用程序，然後將代碼

[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"twitter://"]];
