Facebook和Twitter在iOS中連接

Question

我想連接Facebook和Twitter帳戶與我的iOS應用程序。我正在尋找代碼來檢查帳戶是否存在於設置中。如果存在，則需要使用同一帳戶進行登錄，如果沒有，則要求用戶在設置中添加帳戶。

我嘗試了幾件事情，但真的不工作。如果有人需要我的代碼，那麼讓我知道我會將它發佈到pastebin上。

加入社會框架，以你的項目，並在你的類進口

#import <Social/Social.h> 

對於Facebook而言

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) { 

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; 

    [controller addImage:UIImage]; 
controller.completionHandler = ^(SLComposeViewControllerResult result) { 
    if(result == SLComposeViewControllerResultDone) { 

    } 
    [self dismissViewControllerAnimated:YES completion:nil]; 

}; 
[self presentViewController:controller animated:YES completion:Nil]; 
} 
else 
{ 

//Show Alert: No Facebook Account in Settings Page 

} 

Twitter的

if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeTwitter]) { 

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeTwitter]; 

    [controller addUrl:NSURL]; 
controller.completionHandler = ^(SLComposeViewControllerResult result) { 
    if(result == SLComposeViewControllerResultDone) { 

    } 
    [self dismissViewControllerAnimated:YES completion:nil]; 

}; 
[self presentViewController:controller animated:YES completion:Nil]; 
} 
else 
{ 

//Show Alert: No Twitter Account in Settings Page 

} 

Answer 2

要檢查，如果你可以與Facebook或Twitter分享，使用方法：
[SLComposeViewController isAvailableForServiceType:serviceType]
哪裏的serviceType可以是任何SLServiceTypes如，SLServiceTypeFacebook和SLServiceTypeTwitter

這基本上都會檢查他們是否有本地連接這些服務在他們的設置。我不認爲你可以要求用戶在他們的設置中添加它。大多數情況下，如果沒有UIActionSheet這樣的特定分享選項，它就不會顯示出來。

我的猜測是，您可以使用SLComposeViewController來檢查連接的帳戶，如果沒有連接，請使用相應的SDK將他們的帳戶與您的iOS應用連接。

在你的項目和進口添加Twitter和社會框架中的類文件一樣

#import <Social/Social.h> #import <Twitter/Twitter.h>

For Facebook

如果（[SLComposeViewController isAvailableForServiceType：SLServiceTypeFacebook]）{

SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook]; 

    NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:@"EditImage"]; 
    if (aImgdata) { 
     UIImage *aImage=[UIImage imageWithData:aImgdata]; 
     [controller addImage:aImage]; 
    } 

    controller.completionHandler = ^(SLComposeViewControllerResult result) { 
     if(result == SLComposeViewControllerResultDone) { 

     } 
     [self dismissViewControllerAnimated:YES completion:nil]; 

    }; 
    [self presentViewController:controller animated:YES completion:Nil]; 
} 
else 
{ 

    [self ShowAlertView: @"You can't share on facebook right now, make sure your device has an internet connection and you have at least one Facebook account setup"]; 

} 

For Twitter

如果（[TWTweetComposeViewController canSendTweet]）{

 { 

      TWTweetComposeViewController *tweetViewController = [[TWTweetComposeViewController alloc] init]; 

      NSData *aImgdata=[[NSUserDefaults standardUserDefaults]objectForKey:@"EditImage"]; 
      if (aImgdata) { 
       UIImage *aImage=[UIImage imageWithData:aImgdata]; 
       [tweetViewController addImage:aImage]; 
      } 

      tweetViewController.completionHandler = ^(TWTweetComposeViewControllerResult result) { 
       if(result == TWTweetComposeViewControllerResultDone) { 

        [self ShowAlertView: @"Tweet Has been Shared"]; 

       } 
       [[AppDelegate sharedInstance]showActivity:NO]; 
       [self dismissViewControllerAnimated:YES completion:nil]; 
      }; 

      [self presentViewController:tweetViewController animated:YES completion:nil]; 

     } 

    } else { 

     [self ShowAlertView: @"You can't send a tweet right now, make sure your device has an internet connection and you have at least one Twitter account setup"]; 
    }
