Question

我正在开发一款应用程序，可让用户将自己应用的详细信息分享到Facebook。我有UITableview，其中包含作者姓名列表，当您点击书名时，它会转到另一个UITableView，其中显示每个TableViewCell中该作者的不同书籍。我可以在第二个UITableView中显示列表。我想知道如何分享作者姓名，书名和图像（第2张表格详情）。我正在展示那样做的代码.. 因此，当用户想要分享详细信息时，他必须点击作者UIButton的每个单元格中的UITableView。

didselectatindexpath

    NSDictionary *selectedAuthor = nil;

     NSArray *sectionArray=[mainIndexDictionary objectForKey:[allKeysArray objectAtIndex:indexPath.section]];
        selectedAuthor = [sectionArray objectAtIndex:indexPath.row];
        iPath=[[selectedAuthor objectForKey:@"SymptIndexID"] intValue];
        NSLog(@"iPath - %d",iPath);

        authortitleString=[[selectedAuthor objectForKey:@"authorIndexName"]stringByAppendingString:@" cure!"];
    }


    bookArray=[objDB customCellData:(NSInteger)iPath];
    [self.view bringSubviewToFront:authorView];
    [bookTableView scrollRectToVisible:CGRectMake(0.0, 0.0, 320.0,10.0) animated:NO];

    [bookTableView reloadData]

;

在ios 6.0中您可以实现如下（您必须将social framework添加到您的项目中）

 #import <Social/Social.h>

 - (void)ShareFacebook
 {
    SLComposeViewController *fbController=[SLComposeViewController composeViewControllerForServiceType:SLServiceTypeFacebook];

if([SLComposeViewController isAvailableForServiceType:SLServiceTypeFacebook])
{
    SLComposeViewControllerCompletionHandler __block completionHandler=^(SLComposeViewControllerResult result){

        [fbController dismissViewControllerAnimated:YES completion:nil];

        switch(result){
            case SLComposeViewControllerResultCancelled:
            default:
            {
                NSLog(@"Cancelled.....");
               // [[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];

            }
                break;
            case SLComposeViewControllerResultDone:
            {
                NSLog(@"Posted....");
            }
                break;
        }};


    [fbController setInitialText:@"This is My Sample Text"];


    [fbController setCompletionHandler:completionHandler];
    [self presentViewController:fbController animated:YES completion:nil];
}
else{
    UIAlertView *alert = [[[UIAlertView alloc]initWithTitle:@"Sign in!" message:@"Please first Sign In!" delegate:nil cancelButtonTitle:@"ok" otherButtonTitles:nil, nil]autorelease];
    [alert show];
 }
}

您的问题有点不清楚，但考虑到您已经正确实施了FB ios Api的所有其他方法，您可以使用此代码将文本和图像发布到Fb

SBJSON *jsonWriter = [[SBJSON new] autorelease];

NSDictionary* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
                                                       APP_NAME,@"text", fb_app_url,@"href", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                               APP_NAME, @"name",
                               fb_app_url, @"link",
                               fb_publish_image, @"picture",
                               APP_NAME, @"name",
                               @"Awesome APP", @"caption",
                               [NSString stringWithFormat:@"I am  loving it", GAME_NAME], @"description",
                               @"Get it now!",  @"message",
                               actionLinksStr, @"action_links",
                               nil];

[self.faceBook dialog:@"stream.publish" andParams:params andDelegate:self];
