【问题描述】：

谁能解释我如何使用 FBGraph api 在我的 Facebook 墙上发布将显示网站图像和网址的图像数据？

谢谢，

【问题讨论】：

我试过了，params = [NSMutableDictionary dictionaryWithObjectsAndKeys: upperCaseStatusString, @"message",place_Name,@"name", CheckedFriendsNameStr, @"description", encoded_ImageData, @"picture", @"@987654321 @", @"链接", 无]; [appDelegate.m_Facebook requestWithGraphpath:@"me/photos" andParams:params andHttpMethod:@"POST" andDelegate:self];

通过使用这个，我可以发布图片但无法发布剩余的字段。

【参考方案1】：

试试这个：

    NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:image_url,@"source",image_url, @"link",nil];
    [facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

你好 abi，​​我正在发布 NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:encoded_ImageData,@"source", @"itunes.apple.com/us/app/social-checkin/id504791401?mt=8", @"link",nil]; [appDelegate.m_Facebook requestWithGraphPath:@"me/feed" andParams:params andHttpMethod:@"POST" andDelegate:self];

但是我无法发布我的数据格式的图片，这里只有 iTunes 链接发布

@MeenakshiKatal 这里 ImageData 是一个 NSString 变量，保存要显示的图像的 url。

【参考方案2】：

大家好，现在我可以使用 social.framework 将图像数据和 url 一起发布。

请在您的项目中添加 social.framework 并使用 ios6 继续执行以下代码。

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])

    SLComposeViewController *controller = [SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

    SLComposeViewControllerCompletionHandler myBlock = ^(SLComposeViewControllerResult result)
        if (result == SLComposeViewControllerResultCancelled) 

            NSLog(@"ResultCancelled");

            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"There might be some problem in facebook posting please try agian later." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
            [alert release];

            self.view.userInteractionEnabled = YES;
            [loadingView removeFromSuperview];

         else

        
            UIAlertView *alert = [[UIAlertView alloc]initWithTitle:@"Alert" message:@"We have checked in successfully on facebook." delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];
            [alert show];
            [alert release];

            NSLog(@"Success");

            self.view.userInteractionEnabled = YES;
            [loadingView removeFromSuperview];

        

        [controller dismissViewControllerAnimated:YES completion:Nil];
        [self uploadMessageToTwitter];

    ;

    controller.completionHandler =myBlock;

    [controller addURL:[NSURL URLWithString:@"https://itunes.apple.com/us/app/social-checkin/id504791401?mt=8"]];

    if (self.encoded_ImageData ==nil) 

        [controller addImage:[UIImage imageNamed:@"No_ImageFound.png"]];

    
    else
    

        [controller addImage:[UIImage imageWithData:self.encoded_ImageData]];

    

    NSString *businessName;

    //Set business name string to be passed on facebook
    if (m_BusinessNameString == nil || [m_BusinessNameString isEqualToString:@""])
    
        businessName = @"Business name not specified!";
    
    else
    
        businessName = [m_BusinessNameString uppercaseString];
    

    NSString *nameString = [NSString stringWithFormat:@"CHECKED IN @"];

    //user has checked in with his friends if sc-merchant
    NSString *friendsString;

    if ([checkedFriendsNameArray count] > 0)
    
        NSMutableString *checkedFriendsTempStr = [[NSMutableString alloc] init];

        for (NSMutableString *checkedStr in checkedFriendsNameArray)
        

            [checkedFriendsTempStr appendString:[NSString stringWithFormat:@"%@,",checkedStr]];


            friendsString = [NSString stringWithFormat:@"WITH %@",checkedFriendsTempStr];
        
    
    else

    
        friendsString = [NSString stringWithFormat:@"WITH NO FRIENDS"];

    

    NSString *fname= [[NSUserDefaults standardUserDefaults] valueForKey:@"userfname"];
    NSString *lname= [[NSUserDefaults standardUserDefaults] valueForKey:@"userlname"];

    NSString *name=[fname stringByAppendingString:[NSString stringWithFormat:@"%@",lname]];


    NSString *main_TextString =[NSString stringWithFormat:@"%@ \n %@ %@ %@ %@",upperCaseStatusString,name,nameString,businessName,friendsString];

    [controller setInitialText:main_TextString];

    [self presentViewController:controller animated:YES completion:Nil];



else

    NSLog(@"UnAvailable");
    self.view.userInteractionEnabled = YES;
    [loadingView removeFromSuperview];

【参考方案3】：

尝试像这样通过 fbgraph 发送图片：

- (IBAction)buttonClicked:(id)sender

    NSArray* permissions = [[NSArray alloc] initWithObjects:
                            @"publish_stream", nil];
    [facebook authorize:permissions delegate:self];
    [permissions release];


- (void)fbDidLogin

      NSString *filePath =yourpathToImage;
       NSData *videoData = [NSData dataWithContentsOfFile:filePath];
       NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData, yourpathToImage,
                                   @"picture/jpeg", @"contentType",
                                   @"Video Test Title", @"title",
                                   @"Video Test Description", @"description",
                                   nil];
    [facebook requestWithGraphPath:@"me/photos"
                         andParams:params
                     andHttpMethod:@"POST"
                       andDelegate:self];
 

【讨论】：

你好 Vishal，请解释一下我如何在上面的帖子中发布任何网址？通过使用它，我可以发布图片，但无法使用 :@"me/photos" 参数发布链接。我想将图片数据和 iTunes 链接一起发布。

@Meenakshi Katal 我也没有用这种方法发送 url 我也在搜索如果我成功了我也告诉你。
