如何在facebook iPhone 6中分享带有图片和描述的链接

Question

    UIImage *image = [UIImage imageNamed:@"attachment_blank.png"];
    FBSDKSharePhoto *photo = [FBSDKSharePhoto photoWithImage:image userGenerated:NO];
NSDictionary *properties = @{
                               @"og:type": @"app:recipe",
                               @"og:title": @"Sample Recipe",
                               @"og:description": @"",
                               @"og:url": @"http://samples.ogp.me/216213502062059",
                               @"og:image": @[photo]
                           };
FBSDKShareOpenGraphObject *object = [FBSDKShareOpenGraphObject objectWithProperties:properties];
FBSDKShareAPI *shareAPI = [[FBSDKShareAPI alloc] init];
[shareAPI createOpenGraphObject:object];

提交指南谈到了“用户生成的照片”权限，该权限似乎在应用程序设置中的任何地方都不可用，或者在文档中的任何其他地方都不存在。这仍然是必需的吗？图片有没有类似的权限？

Answer 1

您可以尝试使用此方法与link共享图像。您想要共享的图片必须在服务器上(即您需要使用图片的链接)注意：-您必须拥有来自facebook应用程序的"publish_actions“权限。

下面的方法使用facebook sdk 4.3显示

在.h文件中

#import <FacebookSDK/FacebookSDK.h>
@property (strong, nonatomic) FBRequestConnection *requestConnection;

在.m文件中

-(IBAction)facebookBtn:(id)sender{
    if (!FBSession.activeSession.isOpen) {
    // if the session is closed, then we open it here, and establish a handler for state changes
    [FBSession openActiveSessionWithReadPermissions:@[@"public_profile", @"email", @"user_events", @"user_location", @"publish_actions"]
                                       allowLoginUI:YES
                                  completionHandler:^(FBSession *session,
                                                      FBSessionState state,
                                                      NSError *error) {
                                if (error)
                                {
                                    UIAlertView *alertView = [[UIAlertView alloc]initWithTitle:NSLocalizedString(@"Error", nil) message:error.localizedDescription delegate:nil cancelButtonTitle:@"Ok" otherButtonTitles:nil];

                                          if (error.code!=2)
                                          {
                                              [alertView show];
                                          }

                                      }
                                      else if (session.isOpen)

                                              [self requestCompleted:connection forFbID:@"me" result:result error:error];
