Facebook Share Feed Dialog不再可见，它再次从Facebook Native app重定向到我的应用程序

Question

嗨我使用Facebook Feed分享对话框面对Post图像的奇怪问题。我正在使用这个波纹管代码： -

-(IBAction)shaerFacebook
{

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0];
    NSString *savedImagePath = [documentsDirectory stringByAppendingPathComponent:@"savedImage2.png"];

    NSURL *imageFileURL =[NSURL fileURLWithPath:savedImagePath];

    UIImage *imagetoshare=[UIImage imageWithData:[NSData dataWithContentsOfURL:imageFileURL]];

if ([FBDialogs canPresentShareDialogWithParams:params]) {

        // Present share dialog
        id<FBGraphObject> pictureObject =
        [FBGraphObject openGraphObjectForPostWithType:@"mypicture:picture"
                                                title:@"title"
                                                image:imagetoshare
                                                  url:imagetoshare
                                          description:@""];

        id<FBOpenGraphAction> action = (id<FBOpenGraphAction>)[FBGraphObject graphObject];
        [action setObject:pictureObject forKey:@"picture"];

        [FBDialogs presentShareDialogWithOpenGraphAction:action
                                              actionType:@"Photoshare:cook"
                                     previewPropertyName:@"picture"
                                                 handler:^(FBAppCall *call, NSDictionary *results, NSError *error) {
                                                     if(error) {
                                                         NSLog(@"Error: %@", error.description);
                                                     } else {
                                                         NSLog(@"Success");
                                                     }
                                                 }];



        // If the Facebook app is NOT installed and we can't present the share dialog
    }
}

它将导航facebook原生应用程序显示带有图像的对话框，并且只需一秒钟它将重定向到我无法发布的应用程序。我做了很多谷歌，但没有得到解决方案。请帮我解决这个问题。

Facebook应用程序有任何特定的变化吗？
