Question

我想在iOS应用中使用facebook sdk将一些文字发布到用户墙上。

现在发布一个开放的图形故事是唯一的方法吗？

我发现在开放图形故事中他们真的很奇怪，你只能以“用户x甚至”的格式发布信息，你可以直接在Facebook上预设x和y，比如用户在比萨饼或用户玩游戏。设置每一个也非常费力，因为你必须在外部服务器上为每个对象创建一个.php对象。

我错过了什么或有更简单的方法可以解决这个问题吗？

通过浏览facebook教程了解更多。

-(void) postWithText: (NSString*) message
           ImageName: (NSString*) image
                 URL: (NSString*) url
             Caption: (NSString*) caption
                Name: (NSString*) name
      andDescription: (NSString*) description

从iOS应用分享内容的最简单方法是使用UIActivityViewController类，here您可以找到该类的文档，here是一个很好的使用示例。它很简单：

NSString *textToShare = @”I just shared this from my App”;
UIImage *imageToShare = [UIImage imageNamed:@"Image.png"];
NSURL *urlToShare = [NSURL URLWithString:@"http://www.bronron.com"];
NSArray *activityItems = @[textToShare, imageToShare, urlToShare];

UIActivityViewController *activityVC = [[UIActivityViewController alloc]initWithActivityItems:activityItems applicationActivities:nil];
[self presentViewController:activityVC animated:TRUE completion:nil];

这仅适用于iOS 6，并且它使用在用户设置中配置的Facebook帐户，并且不需要Facebook SDK。

您也可以使用图谱API 。

在使用iOS创建Facebook应用程序的所有基本步骤之后，您可以开始享受Graph API的功能。下面的代码将发布“hello world！”在你的墙上：

#import <FBSDKCoreKit/FBSDKCoreKit.h>
#import <FBSDKLoginKit/FBSDKLoginKit.h>

...

//to get the permission 
//https://developers.facebook.com/docs/facebook-login/ios/permissions  
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
            NSLog(@"publish_actions is already granted.");
        } else {
            FBSDKLoginManager *loginManager = [[FBSDKLoginManager alloc] init];
            [loginManager logInWithPublishPermissions:@[@"publish_actions"] handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
                //TODO: process error or result.
            }];
        }

    if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"]) {
        [[[FBSDKGraphRequest alloc]
          initWithGraphPath:@"me/feed"
          parameters: @{ @"message" : @"hello world!"}
          HTTPMethod:@"POST"]
         startWithCompletionHandler:^(FBSDKGraphRequestConnection *connection, id result, NSError *error) {
             if (!error) {
                 NSLog(@"Post id:%@", result[@"id"]);
             }
         }];
    }
...
