Question

在我发布解析后，我需要帮助将图片发布到tableview上。我正在使用解析和目标-c。我到了你可以发布图片的地方，我可以在解析时看到它，但是如何在我的应用程序或桌面视图中看到时间轴上的图片？

这是我发布到解析的代码，

- (IBAction)uploadButton:(id)sender{
    NSData* data = UIImageJPEGRepresentation(_imageView.image, 100);
    PFFile *imageFile = [PFFile fileWithName:@"Image.jpg" data:data];

    // Save the image to Parse

    [imageFile saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
        if (!error) {
            // The image has now been uploaded to Parse. Associate it with a new object
            PFObject* newPhotoObject = [PFObject objectWithClassName:@"PhotoObject"];
            [newPhotoObject setObject:imageFile forKey:@"image"];

            [newPhotoObject saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
                if (!error) {
                    NSLog(@"Saved");
                    UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Your picture has been successfully uploaded." delegate:self cancelButtonTitle:@"OK" otherButtonTitles:nil];
                    [alert show];

                }
                else{
                    // Error
                    NSLog(@"Error: %@ %@", error, [error userInfo]);
                }
            }];
        }
    }];
}

我还需要做些什么才能看到我在主的tableview页面上发布的内容？

我将视图控制器标记为“发布页面”和“主页面”。 “主页面”是我希望我发布的所有图片最终解析的地方，以及图片的评论部分。

我这样做了，可能对你有用。看一看

-(IBAction)btnUpDateImageClicked:(id)sender
{
    if (UserSelectedImage)
    {
        HUDSHOWWITHTEXT(@"Updating profile");
        PFQuery *query = [PFQuery queryWithClassName:User_Info];
        NSLog(@"->%@",[PFUser currentUser].username);

        [query whereKey:UserName equalTo:[PFUser currentUser].username];

        [query getFirstObjectInBackgroundWithBlock:^(PFObject * user , NSError *error) {
            if (!error) {
                // Found User and modify it

                PFFile *imageFile1,*imageFilePlaceHolder;
                NSData *imageData1,*imageDataPlaceHolder;
                //            PFFile *fileDeleted = [[PFFile alloc] init];

                if (UserSelectedImage) {

                    //User image
                    imageData1 = UIImageJPEGRepresentation(UserSelectedImage, 1.0);
                    imageFile1 = [PFFile fileWithName:@"img.png" data:imageData1];
                    [user setObject:imageFile1 forKey:@"user_image"];

                    //PlaceHolder
                    UIImage *imagPlaceholder = UserSelectedImage;
                    imagPlaceholder = [APP_DELEGATE SyncPlaceHolderImage:imagPlaceholder];
                    imageDataPlaceHolder = UIImageJPEGRepresentation(imagPlaceholder, 1.0);
                    imageFilePlaceHolder = [PFFile fileWithName:@"img.png" data:imageDataPlaceHolder];
                    [user setObject:imageFilePlaceHolder forKey:@"placeholder_image"];
                }
                else {
                    user[@"user_image1"] = [NSNull null];
                    user[@"placeholder_image"] = [NSNull null];
                }


                // Save
                [user saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error) {
                    if (succeeded) {
                        HUDHIDE;

                        if (UserSelectedImage) {
                            APP_DELEGATE.user.pfImageOne        =   imageFile1;
                            APP_DELEGATE.user.pfImagePlaceHolder=   imageFilePlaceHolder;
                        }
                        else {
                            APP_DELEGATE.user.pfImageOne = nil;
                            APP_DELEGATE.user.pfImagePlaceHolder=nil;
                        }

                        ShowAlert(@"Saved SUccesfully");
                    }
                    else
                    {
                        HUDHIDE;
                        ShowAlert(@"Problem updating profile-%@");
                    }
                }];
            } else {
                // Did not find any UserStats for the current user
                NSLog(@"Error: %@", error);
                HUDHIDE;
                ShowAlert(@"Problem updating profile")
            }
        }];
    }
    else
    {
        ShowAlert(@"please select Image");
    }
}
