如何在Facebook iOS SDK中发布或分享？

Question

我试图使用FacebookSDK发布消息或在我的fb中分享照片。我已经按照如何安装它的步骤。我已经完成了应用登录教程，但现在的问题是如何使用我的应用程序发布消息或将其分享到我的FB中。有很多这样的教程one。我认为这对于FacebookSDK已经很老了。对不起如果我是这样的noob。我知道这不是发布此页面的正确页面，但我现在不知道。如果您有关于如何发布或分享的教程。请给我链接。如果有的话，你能为此提供一些步骤吗？

我已经尝试this了，但它没有发布或分享。

更新

这是我的代码

import "ShareController.h"
#import <FBSDKShareKit/FBSDKShareKit.h>
#import <FBSDKMessengerShareKit/FBSDKMessengerShareKit.h>


@implementation ShareController

- (void)viewDidLoad {
    [super viewDidLoad];

    FBSDKShareLinkContent *content = [[FBSDKShareLinkContent alloc] init];
    content.contentURL = [NSURL URLWithString:@"https://developers.facebook.com"];

    FBSDKShareButton *button = [[FBSDKShareButton alloc] init];
    button.shareContent = content;
    [self.view addSubview:button];
}

- (IBAction)shareButton:(id)sender {


    UIImage * image = [UIImage imageNamed:@"sample.png"];

    FBSDKSharePhoto *photo = [[FBSDKSharePhoto alloc] init];
    photo.image = image;
    photo.userGenerated = YES;
    FBSDKSharePhotoContent *content = [[FBSDKSharePhotoContent alloc] init];
    content.photos = @[photo];

    FBSDKShareDialog *dialog = [[FBSDKShareDialog alloc] init];
    dialog.fromViewController = self;
    dialog.shareContent= content;
    dialog.mode = FBSDKShareDialogModeShareSheet;
    [dialog show];
}

这是我登录的代码。我认为这是简单的代码

@implementation ViewController

- (void)viewDidLoad {
    [super viewDidLoad];

    FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
    loginButton.center = self.view.center;
    [self.view addSubview:loginButton];
    // Do any additional setup after loading the view, typically from a nib.
}

您未设置权限，以设置权限：

FBSDKLoginButton *loginButton = [[FBSDKLoginButton alloc] init];
loginButton.center = self.view.center;
[loginButton logInWithPublishPermissions: @[@"publish_actions"] fromViewController:self handler:^(FBSDKLoginManagerLoginResult *result, NSError *error) {
if (error) {
  NSLog(@"Process error");
} else if (result.isCancelled) {
  NSLog(@"Cancelled");
} else {
  NSLog(@"Logged in");
  }
}];

最好检查用户是否已在IBAction方法中授予权限：

- (IBAction)shareButton:(id)sender {
if ([[FBSDKAccessToken currentAccessToken] hasGranted:@"publish_actions"])
{
    // code to share 
}
}
