I have upload images with url image successful on this way
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"https://developers.facebook.com/docs/reference/dialogs/", #"link",
#"http://fbrell.com/f8.jpg", #"picture",
#"Facebook Dialogs", #"name",
#"Reference Documentation", #"caption",
#"Using Dialogs to interact with users.", #"description",
nil];
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[[delegate facebook] dialog:#"feed"
andParams:params
andDelegate:self];
Now i want to upload image from a local image in same way
like
profImg = [UIImage imageNamed:LoginWithFacebookNormal#2x.png"];
NSData *data = [NSData dataWithData:UIImagePNGRepresentation(profImg)];
i have used data, #"picture", in dictionary but it's give me error
is it any other way to upload local/Gallery/resource image with dialog box + comment area ?
I have searched but every time found that only url image can feed the dialog box
I have used Hackgraph tutorial for this posting.
Note: I am not using Sharekit or any other API i have used only Graph API
Finally after lots of research I get the example of Facebook. Download the example from here. You have to make modification because currently example hold static image.

How to post photos to facebook iphone fbconnect
I am using FB SDK and getting an error while uploading picture on FB post from my app
in my view did load i have and UIImageView which has an image that i need to be posted on FB the code of the view did load
ImageView = [[UIImageView alloc] initWithFrame:CGRectMake(0, 0, 65, 65)];
ImageView.center = CGPointMake(42, 43);
[View addSubview:ImageView];
and in my method of FB post i did this
UIImage *image = [[UIImage alloc]init];
image = ImageView.image;
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithCapacity:3];
[params setObject:#"LINK_HERE" forKey:#"link"];
// due to this line below, i am getting an error :
// "[UIImage length]: unrecognized selector sent to instance 0x170fa0e0"
// and if use http link instead of image(UIImage) it works, but i want to use my image
[params setObject:image forKey:#"picture"];
[params setObject:#"NAME_HERE" forKey:#"name"];
[params setObject:#"DEC_HERE" forKey:#"description"];
// Invoke the dialog
[self.facebook dialog:#"feed" andParams:params andDelegate:self];
How should i use my UIImage inside this code ... any idea ??
You can only upload URL based images in Facebook dialog method..Images generated within the app or within app bundle cant be uploaded..
To upload those images you have to use graph API
sample code
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
image, #"source",
#"caption desc", #"message",
nil];
[facebook requestWithGraphPath:[NSString stringWithFormat:#"/me/photos?access_token=%#", self.facebook.accessToken]
andParams:params andHttpMethod:#"POST" andDelegate:self];
you can post your image simply like this
UIImage *imgSource = {insert your image here};
NSString *strMessage = #"Images Description";
NSMutableDictionary* photosParams = [NSMutableDictionary dictionaryWithObjectsAndKeys:
imgSource,#"source",
strMessage,#"message",
nil];
[self.facebook requestWithGraphPath:#"me/photos"
andParams:photosParams
andHttpMethod:#"POST"
andDelegate:self];
There is a sample app in facebook sdk, please check that.

I want to post a link including an image to Facebook timeline:
UIImage *img = [UIImage imageNamed:#"1.png"];
self.postParams =
[[NSMutableDictionary alloc] initWithObjectsAndKeys:
#"Here we go", #"message",
#"https://developers.facebook.com/ios", #"link",
UIImagePNGRepresentation(img), #"picture",
#"Facebook SDK for iOS", #"name",
#"Build great social apps and get more installs.", #"caption",
#"The Facebook SDK for iOS makes it easier and faster to develop Facebook integrated iOS apps.", #"description",
nil];
[FBRequestConnection startWithGraphPath:#"me/feed" parameters:self.postParams HTTPMethod:#"POST"
completionHandler:^(FBRequestConnection *connection, id result, NSError *error) {
[self showAlert:#"Link is posted" result:result error:error];
}];
The UIImage does not posted. Can you help me?
But simply if I use :
#"https://developers.facebook.com/attachment/iossdk_logo.png", #"picture"
it works.
If you read the documentation, it says the "picture" parameter should be of type string ie: a url. You can not post an image and a message from the mobile SDKs at the same time without some clever hackory: see me/photos in the documentation but your options are severely limited.
I want to use the Facebook Graph API in a NATIVE iPhone Application. Has anybody been able to find a way to post images/message on a user's feed?
I have tried all possible ways to post a ‘picture’ (not a URL but a UIImage) on the feed and have been working on this for 2 weeks now.
If you go to facebook.com you can upload a picture from your computer on to the wall. I am using ASIHTTPRequest to work on facebook graph API.
This is the nearest I have gone to posting a picture on the feed. So if I have a ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:url];
The url is https://graph.facebook.com/me/feed
Now to post a picture I do the following:
[request setPostValue:#"My Message" forKey:#"message"];
[request setPostValue:#"somepic.png" forKey:#"picture"];
[request setPostValue:#"Some Name" forKey:#"name"];
[request setPostValue:#"Some description" forKey:#"description];
[request startAsynchronous];
If you try this then everything works fine other than the picture being posted. A blank placeholder for the picture is though show on the feed.
I created a method to help me do this. Hope this is of some help.
Please read the tutorial on how to set up the Facebook SDK.
-(void) updateStatusWithText:(NSString *) fbTitle //Status title
andStoryURL:(NSString *) fbURL //URL for the story
andStory:(NSString *) fbStory //The story
andImage:(NSString *) imageURL //Image to be displayed.
andPrompt:(NSString *) promptString{
NSLog(#"updateStatusWithText");
NSString *attachmentText =[NSString stringWithFormat:#"{\"name\":\"%#\","
"\"href\":\"%#\","
"\"description\":\"%#\","
"\"media\":[{\"type\":\"image\","
"\"src\":\"%#\","
"\"href\":\"%#\"}],"
"\"properties\":{\"Uploaded from an iPhone\":{\"text\":\"AFL Fan\",\"href\":\"Your itunes apstore URL\"}}}", fbTitle, fbURL, fbStory,imageURL,fbURL];
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
promptString, #"user_message_prompt",
// actionLinksStr, #"properties",
attachmentText, #"attachment",
nil];
NSLog (#"attachmentText : %#", attachmentText);
[facebook dialog:#"stream.publish"
andParams:params
andDelegate:self];
}
i've configured FBConnect and it uploads to the wall, but what i want to do is take a screenshot and then upload the screenshot to FB.
In the below code there is an image but as a url. Can i intersect this and put in my screenshot image?
FBStreamDialog *dialog = [[[FBStreamDialog alloc] init]autorelease];
dialog.userMessagePrompt = #"Tell your friends about Fridgit!!:";
dialog.attachment = [NSString stringWithFormat:#"{\"name\":\"Facebook Connect for iPhone\",\"href\":\"http://developers.facebook.com/connect.phptab=iphone\",\"caption\":\"Caption\",\"description\":\"Description\",\"media\":[{\"type\":\"image\",\"src\":\"screenShot\",\"href\":\"http://developers.facebook.com/connect.php?tab=iphone/\"}],\"properties\":{\"another link\":{\"text\":\"Facebook home page\",\"href\":\"http://www.facebook.com\"}}}", self.screenShot];
[dialog show];
}
i know all the code is default i haven't edited it yet incase i can't do what i want to do.
Cheers
Yes its possible with the new FB API nw, they made it as simple as possible
// code snippet to take a snapshot
// REF: http://stackoverflow.com/questions/2200736/how-to-take-a-screenshot-programmatically
UIGraphicsBeginImageContext(self.window.bounds.size);
[self.window.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *img = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
img, #"picture",
nil];
[_facebook requestWithGraphPath:#"me/photos"
andParams:params
andHttpMethod:#"POST"
andDelegate:self];
is possible custominzing the FBdialog??, i have already modify the attachment on the dialog when the user wants to publish a post; but i need to make hidden the textfield that the dialog presents...there is a way to access to this property or it's just a webView that load a page from facebook's server?
sorry for my bad english!
thanks in advance
Yes, this is possible. just design your own UI and pass the message to a method containing this code:
NSString *message = #"test message here";
NSMutableDictionary *params = [NSMutableDictionary dictionary];
[params setObject:message forKey:#"message"];
[params setObject:toID forKey:#"target_id"];
[[FBRequest requestWithDelegate:self] call:#"facebook.Stream.publish" params:params];
