Hi,

I'm using the FBAgent last modified on Jan 13th at 12:47pm. My loginviewcontroller is the FacebookAgentDelegate (I set the protocol).

Did you put this line in your viewcontroller.h?

#import "FacebookAgent.h"

And you need to add all the sourcecode of facebook agent AND facebook connect to your project too.

[jbellanca]

Thank you so much for this - that's awesome!!!

[Vonswanko]

This is some awesome code here. I am really new at all of this, but have managed to get it almost working the way I need it. I would like to have it take a screen shot of the view, and upload it to face book. I have it uploading the view, but not a screenshot of other things that are in the view. hope that makes sense.

I have been using a screenshot button, to save to the camera roll, and would like to use that same type of button to send to facebook.

any help here would be great.

[AmanApps]

if you want the screeshot the following link may come into help:

Apple - Support - Discussions - (iphone) application screenshot from ...

Thanks.

[Vonswanko]

Hey thanks so much. I figured it out, was just using the wrong name for my image that I wanted to keep and upload. Now to submit the update to Apple and play the waiting game

Thanks again for the help.

[AmanApps]

don't forget to share your app link once approved... i will love to play that (if affordable )

Best of luck.

Best of luck.

Its in the app store now..free version

paid version..this is the one I will be putting the facebook connect in.

The free version just has ads..but all the same functions.

Thanks again.

[Vonswanko]

OK, so here's a bug I have found. Updates the pic to an album, but if the user hasn't given the album permission, it crashes. And also, sometimes after posting an update, with pic, after having the app open for a couple of seconds, it just crashes.

[AmanApps]

Thanx Vonswanko for the bug report. Could tress where is the prob?

[Vonswanko]

Not sure where the problem is, but it may be in the way it grabs the screenshot. Going to try a few other things. One other problem is that it will sometimes crash after invoking the Facebook connect, after signing in, then hit connect. But it still sends the pic. Weird.

After February 17, Facebook seems to suddenly could not upload a picture, and with the App Store's Facebook APP can not upload pictures. Facebook App's review have complained that the pictures can not upload

[zxl777]

With the developer account sign in Facebook, i can successfully upload a picture, and directly see the news feed.
With other ordinary account login Facebook, i can successfully upload a picture, but I can not see the news feed,
Then found in Facebook - "in Your Photos - iToyTools Photos can be seen "This album contains photos uploaded from another application. Select photos to approve or reject."

Must approve the photos then photo appear in the news feed.

Is it must "submit your application to the directory"

[rocotilos]

Yup, that is normal I think. Photos uploaded by apps need a consent from user first.

But The Facebook APP in App Store can upload photo, and do not need a consent from user first.

So i think how to do that?

[zxl777]

I am sure I found 2 bug
1, upper right corner of the dialog box is not the Close button (X), re-add FBConnect.bundle can resolve this problem.

2, if only call a function to upload pictures, there is no implementation of the [self askPermission];, the consequences can not update the status, upload pictures are in the auditing of the state.
Want to have a good approach, want to update, thank you

[Vonswanko]

I finally figured out the crash after uploading issue. With a little reading in some other threads, I changed these 2 things:

1. Using NSMutableDictionary in agent instead of NSDictionary
2. In the request, using photos.upload instead of facebook.photos.upload,




Thanks to all on this site, and for this drop in code.

[youknowho]

I'm getting an EXC_BAD_ACCESS crash when uploading an image. I've confirmed that the image data is good, since I used it with Facebook Connect as well. For the image data I do:

NSData *imageData = UIImageJPEGRepresentation(self.myImage, 1.0);
[fbAgent uploadPhotoAsData:imageData withStatus:statusText.text caption:nil toAlbum:nil];

I've already made the NSDictionary -> NSMutableDictionary change mentioned in FacebookAgent.m.
Has anyone else had this issue or found a solution?

How to get friends list, then post news to friend's Wall?

[AmanApps]

hi, actually it is very simple and basic implementation with minimum to no testing.

I wish i could work on these but got stuck with new game and tons of work

feel free to update and use as you want

[hobbyCoder]

My gosh this code is helpful!

I have everything working fairly well in my new facebook intergrated app, thanks to this generous code. I upload the photo first (which, as has been mentioned, posts a somewhat unwanted entry to their wall about the photo itself, but it's not too bad), the actual call is just:

[fbAgent uploadPhotoAsData:myData withCaption:nil toAlbum:nil];

Then I wrote this method, which triggers when the upload completes (a second or two):

- (void) facebookAgent:(FacebookAgent*)agent photoUploaded:(NSString*) pid{
	currentPid = pid;
	
	currentPhotoURL = [NSMutableString stringWithFormat: @"http://www.facebook.com/photo.php?pid="];
	NSString *endNumbers = [currentPid substringWithRange: NSMakeRange(16,5)]; // ex: 100000864320548_21858
	NSString *startNumbers = [currentPid substringWithRange: NSMakeRange(0,15)];
	[currentPhotoURL appendString:endNumbers];
	[currentPhotoURL appendString:@"&id="];
	[currentPhotoURL appendString:startNumbers];
	NSLog(@"The URL we're going to use is: %@", currentPhotoURL);
	[self publishStream];
}

That way I know what the URL is for photo we just uploaded, but I avoided fql calls because I am too dumb to comprehend them... this is a bit hackish, but I doubt it will break anytime too soon.

And as you can see, that calls my publishStream method:

- (void) publishStream {
	[[BusyAgent defaultAgent] makeBusy:NO];
		[fbAgent publishFeedWithName:@"Boy am iSorry!" 
						 captionText:@"Please accept this heartfelt apology note." 
							imageurl:@"http://renditionsdesign.com/iSorry_example.png"  
							 linkurl:currentPhotoURL
				   userMessagePrompt:@"What's on your mind?" 
						 actionLabel:@"iSorry for iPhone"
						  actionText:@"Available on the App Store" 
						  actionLink:@"http://itunes.apple.com/us/app/magic-card/id290645875?mt=8"];
}

(I realize it links to a different one of my apps for now, I'll fix that link eventually)

So, everything works fine, and I'm so happy! But only on the simulator. There has been discussion about a bug in this FaceBook agent code that used NSDictionary when NSMutableDictionary is needed, but I can't seem to solve my problem by changing that.

The console log from my crashed device is:

I hope my code above / explanation of how to do facebook status postings "farmville style" is helpful to someone. Anybody have any idea what I need to do to make this run on an actual device?

[hobbyCoder]

It's definitely the call to uploadPhotoAsData that kills it, not the actual publishing of the stream or any of the little things I do during the process, I've been able to narrow it down pretty conclusively to that.

I just don't really understand the code in the FacebookAgent.m file well enough to fix it (he's a better programmer than me, that's for sure).

[fbAgent uploadPhotoAsData:myData withCaption:nil toAlbum:nil];

Also, even if I use the nifty sample project that AmanApps posted (Facebook Agent Test) it crashes in exactly the same way if I use uploadPhotoAtURL or uploadPhotoAsData. Anyone else see a bug in there that we can fix? I know there are others with variations on this same problem. Maybe I just don't understand the NSDictionary ---> NSMutableDictionary fix that was mentioned....?

[zxl777]

Now there are always users to complain, APP tips are sent successfully, but has nothing on the WALL.

I re-register a new facebook account and then upload the picture test, is completely successful.

This problem is strange, because I can not reproduce the problems encountered by users.

Have you found this problem? How to solve?

[scotopia]

Hey Aman,

I'm suddenly having a bizarre problem when trying to publish a feed with facebook connect; it used to work but now when I hit my button that tells it to publish a feed, the facebook popup window comes up as usual, the activity meter spins for a second as usual...but then the activity meter disappears and the white popup just stays there forever...feed never gets published. Did something change in FB Connect recently or something? It's possible I somehow changed something to screw it up. It's worth noting that I can do a regular status update just fine. Here's some sample relevant code:

//this works
[fbAgent setStatus:[NSString stringWithFormat: @"%@", rootViewController.mainView.myLabel.text]];

//wheras this does not anymore..
[fbAgent publishFeedWithName:rootViewController.mainView.myLabel.text
						 captionText:@"Some Caption"
							imageurl:@"http://www.myserver.com/someImage.jpg"
							 linkurl:@"http://www.google.com"
						 actionLabel:@"Please Work"
						  actionText:@"Damn!" 
						  actionLink:@"http://www.google.com"];

THis is the last thing standing in my way of release...please help; thanks!
