为什么突然间我的iOS应用程序不能将状态更新发布到Facebook [英] Why suddenly my iOS app can not post status update to Facebook

问题描述

我可以通过我几天前开发的iOS应用程序向Facebook用户端发布状态更新。然后我可能不小心删除了一些东西，现在我不能发布并收到错误消息。相关代码是A：

  message = @test; 
 [FBRequestConnection startForPostStatusUpdate：message 
 completionHandler：^（FBRequestConnection * connection，id result，NSError * error）{
} 
  
  [FBRequestConnection startWithGraphPath：@我/ feed参数：postParams HTTPMethod：@POSTcompletionHandler：^（FBRequestConnection * connection，id result，NSError * error）
  
我收到相同的错误信息：操作无法完成。 （com.facebook.sdk错误5。）
 
 
 
我也注意到，无论是使用FacebookSDK.h还是Facebook.h，我也想知道为什么FacebookSDK.h足以支持上述两种方法，为什么教程建议不推荐使用Facebook.h。
 
 
 
有趣的是，我去检查另一个测试iOS应用程序，我记得可以发布Facebook状态更新，发现它不能发布任何想法？
解决方案
我决定使用iOS6功能SLComposeViewController，这使得发布Facebook状态更新了一块蛋糕。
 
 
 
在.m文件中添加社交框架后，您可以这样做：
   - （IBAction）clickMe :( UIButton *）发件人{
 NSLog（@你点击了我）; 
 if（[SLComposeViewController isAvailableForServiceType：SLServiceTypeFacebook]）{
 
 SLComposeViewController * myFB = [S LComposeViewController composeViewControllerForServiceType：SLServiceTypeFacebook]; 
 
 
 SLComposeViewControllerCompletionHandler myBlock = ^（SLComposeViewControllerResult result）{
 if（result == SLComposeViewControllerResultCancelled）{
 NSLog（@cancelled） 
} else {
 NSLog（@哦yeah）; 
} 
 [myFB dismissViewControllerAnimated：YES完成：nil]; 
}; 
 myFB.completionHandler = myBlock; 
 [myFB setInitialText：@从我的应用程序发布。]; 
 [self presentViewController：myFB动画：YES完成：nil]; 
 
} 
 
} 
  
 
I was able to post a status update to Facebook user wall through the iOS app I'm developing a few days ago. Then I probably accidentally removed something, I now cannot post and get error message. The relevant code is A:
    message = @"test";
    [FBRequestConnection startForPostStatusUpdate:message
    completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
    }
I also tried following method B:
    [FBRequestConnection startWithGraphPath:@"me/feed" parameters:postParams HTTPMethod:@"POST" completionHandler:^(FBRequestConnection *connection,id result,NSError *error)
and I got same error message: The operation couldn’t be completed. (com.facebook.sdk error 5.)"

I also noticed doesn't matter if I use FacebookSDK.h or Facebook.h for either method, both (four ways) would all get the same error message above. I also wonder why FacebookSDK.h is enough to support two methods above, why the tutorial suggests deprecated Facebook.h.

Interesting, I went to check another testing iOS app that I remember could post Facebook status update, and found it could not post either. Any idea?
解决方案
I decided to use iOS6 feature SLComposeViewController, which makes posting Facebook status update a piece of cake.

After add Social framework  in your .m file, you can do sth like this:
    - (IBAction)clickMe:(UIButton *)sender {
         NSLog(@"you clicked me");
         if ([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook]) {

       SLComposeViewController* myFB = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];


          SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result) {
            if (result == SLComposeViewControllerResultCancelled) {
                NSLog(@"cancelled");
           } else {
               NSLog(@"oh yeah");
           }
        [myFB dismissViewControllerAnimated:YES completion:nil];
    };
    myFB.completionHandler = myBlock;
    [myFB setInitialText:@"Posting from my app."];
    [self presentViewController:myFB animated:YES completion:nil];

    }

    }
