PLEASE JOIN THE PROJECT

This project is now obsolete since I found facebook released a great class!!

check out here : http://github.com/facebook/facebook-ios-sdk

Today most of the applications we build have a common feature: Socialize! One common way to achieve this my integrating Facebook within the app.

In my earlier post I have shared a helper class for paginating data. Today I will share how I integrate facebook connect in iPhone apps. I humble admit I am a lazy, if not busy, developer who doesn’t like to write same code again again.

For iPhone applications FacebookConnect is the only way to integrate facebook social features. Facebook team has developed a sdk for iPhone. A sample code showing the use and integration of Facebook Connect in your application. This is quite simple and also tons of tutorials, forums, e-books and videos are out here on the web.

Well, I’m not gonna add few more grams on that! Rather I am going to share how I integrates facebook connects into my apps.

Firstly, let us see what are the steps to add facebook connect. You can also check out this tutorial on facebook wiki or watch the video Implement Facebook Connect on the iPhone in 5 minutes.

Basically the steps for publishing a feed are:

1. Download the sdk.

2. Add the connect source file in your project.
project
3. Update the settings to make FBConnect.h in you header path.

4. In the controller class, have session member variable, many delegate methods.

5. Have a login button to show the login prompt.

6. Once logged in, prepare an attachment json string and show the feed dialog.

These steps are quite simple but if you are a busy programmer and need to work on many projects these steps may be little bothering since you have to rewrite all the codes for loggin in, showing dialogs, handle login events etc.

So, I just encapsulated these repetitive work into a class named FacebookAgent and defined a simple protocol to work on.

Lets see how we can use it.

Objective: Create a simple view based application and publish a feed using FacebookAgent.

1. Download this folder FacebookAgent.zip.

It also includes facebook connect sdk. So you don’t need to add this sdk elsewhere or even update any project settings for this purpose.

2. Create a new project, name it FacebookAgentTest. Righ click on the project in the XCode and select Add existing files. Add the FacebookAgent Folder to your classes. Check copy the source files.

Add FacebookAgent folder to your project

3. In the FacebookAgentTestViewController.h, import FacebookAgent.h and implement protocol FacebookAgentDelegate.

@interface FacebookAgentTestViewController : UIViewController {
...

4. Declare a member variable of type FacebookAgent.

FacebookAgent* fbAgent;

5. Open FacebookAgentTest.m and initialize fbAgent in viewDidLoad method.

fbAgent = [[FacebookAgent alloc] initWithApiKey:@"PLACE YOUR FACEBOOK APPLICATION API KEY"
										  ApiSecret:@"PLACE YOUR FACEBOOK APPLICATION API SECRET"
										   ApiProxy:nil];
	fbAgent.delegate = self;

6. Declare an IBAction method in the FacebookAgentTest.h file.

-(IBAction)updateStatus:(id)sender;

7. Define the above method in FacebookAgentTest.m file.

-(IBAction)updateStatus:(id)sender{
}

8. Open FacebookAgentTestViewController.xib and add a button in the view and connect the above method on its touchesUpInside signal.

9. Now just add the following lines in the updateStatus method to publish a feed!

-(IBAction)updateStatus:(id)sender{
[fbAgent publishFeedWithName:@"Hellow world"
					 captionText:@"how are you?"
						imageurl:@"http://amanpages.com/wordpress/wp-content/uploads/2009/12/logo2.png"
						 linkurl:@"http://amanpages.com/"
			   userMessagePrompt:@"What do you think:"];
}

This code will first check if the user is logged in. If logged in it will show the feed dialog.
If the user is not logged in already, first the login dialog will be shown, after logging in, the feed dialog will be shown automatically!

But one minute, there is one require method in the FacebookAgentDelegate protocol. So, you need to define this:

- (void) facebookAgent:(FacebookAgent*)agent loginStatus:(BOOL) loggedIn{
}

Above method is called when the user logs in or logs out of the facebook. If you use any login button which is very likely, you may change the button title here.

10. Try updating your status. For this use this line:

[fbAgent setStatus:@"status from iPhone 1"];

This will first check if the user is logged in. if not logged in, then it will show the login prompt first.
After log in it will check if extended permission is enabled for this app. if not it will show the permission dialog.
Having given the permission, it will change the user status.

BUT.

11. You need to two more FacebookAgentDelegate method if you want to change status:

- (void) facebookAgent:(FacebookAgent*)agent requestFaild:(NSString*) message{
}
- (void) facebookAgent:(FacebookAgent*)agent statusChanged:(BOOL) success{
}

12. Thats all Run the app!

You can look into the FacebookAgent.h for more detail. It is well documented. If you still have some question shoot here or drop me mail.
Feel free to use this classes without any restriction but I will appreciate if you let me know in which app you are using it

What can be done now using FacebookAgent:
1. Fetch user name:
For this after initialization, set shouldFetchUsernameAfterLogin = YES.

fbAgent.shouldFetchUsernameAfterLogin = YES

and also define the corresponding delegate method:

- (void) facebookAgent:(FacebookAgent*)agent didLoadName:(NSString*) name{
    //use the name
}

2. Make your own attachment and publish a feed.

// this method has some over loaded versions too
- (void) publishFeed:(NSString*)attachement;

3. Publish feed by passing, name, caption, image and link url.

// this method has some over loaded versions too
/**
 * Let the agent make attachement for you. You just pass the information
 *
 */
- (void) publishFeedWithName:(NSString*)name
			 captionText:(NSString*)caption
					   imageurl:(NSString*)url
						linkurl:(NSString*)href
			  userMessagePrompt:(NSString*)prompt;

4. upload a photo

- (void) uploadPhoto:(NSString*)imageurl;

6. ask for extended permission

- (void) askPermission;

7. login and logout

- (void) login;
- (void) logout;

The delegates also offers some handy callback options like:

/**
 * Must define this method if setStatus is called
 *
 * This method is called when user status is changed either successfully or not
 */
- (void) facebookAgent:(FacebookAgent*)agent statusChanged:(BOOL) success;

/**
 * Must define this method if shouldFetchUsernameAfterLogin is set YES
 *
 * This method is called after the agent fetched facebook profile name
 */
- (void) facebookAgent:(FacebookAgent*)agent didLoadName:(NSString*) name;

/**
 * Must define this method if uploadPhoto is called
 *
 * This method is called after photo is uploaded
 */
- (void) facebookAgent:(FacebookAgent*)agent photoUploaded:(NSString*) pid;

/**
 * Must impement this method if any of the above method is defined
 *
 * This method is called if the agent fails to perform any of the above three actions
 */
- (void) facebookAgent:(FacebookAgent*)agent requestFaild:(NSString*) message;

@required

/**
 * This method is called if after login or logout
 */
- (void) facebookAgent:(FacebookAgent*)agent loginStatus:(BOOL) loggedIn;

Here is the demo project. DONT FORGET TO ADD YOUR key and secret!!

Hello. I tried the example, the publish feed works fine and when using the image url I see the image on the facebook wall as expected. great!

But if I run this code :

NSData * myData = UIImageJPEGRepresentation(imageView.image,1);
[fbAgent uploadPhotoAsData:myData withCaption:@"a caption" toAlbum:@"an album"];

The application crashes after I have logged in to facebook with this in the console :

2010-01-21 18:14:13.997 facebookExperiments[4520:207] *** Terminating app due to uncaught exception ‘NSInternalInconsistencyException’, reason: ‘*** -[NSCFDictionary setObject:forKey:]: mutating method sent to immutable object’
2010-01-21 18:14:13.999 facebookExperiments[4520:207] Stack: (
29402203, etc etc

I have an image in my imageView, the code is run by a button press in a view controller.

I also tried it with UIImagePNGRepresentation in case the data is required in that format, with the same result.

Am I doing something wrong?

http://www.amanpages.com/ Shaikh Sonny Aman

hello dev,
sorry, it was a bug, my mistake.

Please go to near line 202 in FacebookAgent.m. You will find a method like this:
-(void)uploadImage{
NSDictionary *params;
—
change NSDictionary to NSMutableDictionary.

Great, this is really helpful so far! I like how you fit everything into just one header and one implementation file.

Is there any way to automatically create a photo album if it doesn’t already exist? Right now, I’m getting a “Error(120) Invalid album id” response when trying to upload a photo. I’d like it to try to create a photo album called “My Drawings” and I’m not sure how to integrate this with fbAgent
Cam

Nevermind, I just replaced the album name string with nil, and that worked!

Aman, Thanks for this. I’ve been playing with the project all afternoon and would love to use this in my next app and give you proper credit. Shoot me an email to jorge AT ripprapp DOT com and let me know if there’s anything in particular you’d like to see, I can also give you some info about the app

Hello Shaikh good work.
Can you please tell that how can I use “Attach” feature of facebook for url’s in which they fetch thumbnail, title and description of any url pasted by user and then he/she can share it.

This looks excellent. Thanks for sharing the code.

I have a question: what are the terms for using this code in our own projects?

Thanks!

Great Code – working perfect within my app…

1 question: if the user ticks ‘keep me logged in’…how long does it keep them logged in for? Or is it permenant? If so, is there a way we can give them the option to log out ?

(This is to avoid someone posting to their wall if they, say, leave their phone laying around).

Thanks very much

http://twitter.com/ColouredRobot ✔ Victor Alexander

From my experience it seems like it keeps them logged in for the duration of the app. If they exit and return, it seems like you have to log in again but the email is saved into the username form.

HI

this tutorial very kind and useful to implement the application,Thanks and congrats for your work.
i have small doubt in this ,usually you have uploading the image URL,in my case i have to upload the browsed image from the photo album.which returns me the UIImage not NSString.may i know what changes i have to do,to solve my problem.

Thans In advance.waiting for your response.
small suggestion to you.im very new to iphone development,can you post how to use the webservice and can you get me the same like this

http://www.amanpages.com/ Shaikh Sonny Aman

while publishing a feed to facebook, you have to provide an image url which is already uploaded to some server.

Directly uploading an image is not supported yet, AFAIK .

I have not yet consumed any web service from iphone, if I do i will share for sure

thanks.

Aman bhai, user’s need to provide their username and password for the twitter app, isnt it? But what do you think about developing somethign like ping.fm – like you configure the services in your browser with a native account (via oAuth) , and then using that username and password you can just loginto your native iphone apps (NSMutableURL) and publish the status

http://www.amanpages.com/ Shaikh Sonny Aman

sounds interesting… need to talk in more details. thanks.

Hi and thanks for the great help!

One question; in a multiview application, if I want to use Facebook functionality in different parts of my app (login in the first view, upload a pic in the second and change status in the third) how shall I use the fbAgent? Is it ok to create it in the app delegate and then access it from the other views of my application?

http://www.amanpages.com/ Shaikh Sonny Aman

not sure.. may be it can be done… if you can plz share how you did it

thanks.. waiting for you reply…..

Phios

I’m afraid I can’t get it working right. What do you think is the best place to put the facebookAgent object? In the app delegate or in the root view controller? if it is in the root view controller, is there a way to retrieve the facebookAgent from its subviews..?

I’m afraid I’m not ready for that kind of stuff yet

CarBoyCam

I reckon that’s possible

e.g. [appDelegate.fbAgent login]; or whatever.

http://www.amanpages.com/ Shaikh Sonny Aman

Great! I will really appreciate if you share the solution.

Thanks.

I think you’d have to import your App Delegate.h file (#import “YourAppDelegate.h”), after setting up fbAgent in your delegate of course.

Then declare your app delegate in your view’s .m file like so:

YourAppDelegate *appDelegate = (YourAppDelegate *)[[UIApplication sharedApplication] delegate];

Then when you want to update the status etc. do this:

[appDelegate.fbAgent setStatus:@"appDelegate FTW!"];

That might work. Haven’t tested it myself.

yea,,, that can be done.. but actually I was talking about
publishing/linking a URL with status using facebook connect.

So, I’m trying this out now.
In my app delegate .m file, and in the application:didFinishLaunchingWithOptions I allocate the FacebookAgent object. I have never touched this file before, so I’m not sure if this is ok or terribly wrong..
However I have access through appDelegate.fbAgent to all my other views – now I’m testing if login, logout, posting etc works as it should.

Hey, I’m using your FacebookAgent class in my App (PlayStation.News) but I’m having one, relatively major problem.

When I use the code:

[fbAgent publishFeedWithName:… blah blah

I can’t seem to get ANY linkurl string to work. It posts to my Facebook wall absolutely fine, but no hyperlink to lead the user to the news story posted…

Did you ever get this to work? It won’t work for me either.

Hi Aman,
Great set of code here. It’s saved me a ton of work.
The only problem I am having is with uploading pictures. I’m getting the “Error(120) Invalid album id” response when trying.
I tried replacing the album name string with nil as someone said in the comments, but now it errs out with a “NSInvalidArgumentException” error.
Any idea what could be the issue? This is the final piece of the puzzle to having my program final.
Thanks for any help you can give.
feel free to email me at aaron at 19w dot com

Is there any way to set the message edit box contents with publishFeedWithName that appears within the “Publish Story” (FBStreamDialog) dialog.

I need to populate the edit box with information from my app – not simply have an empty edit box.

Hi
First of all thanks for the tutorial. It was really helpful. But I have a problem. What to do if I had to post a static data from my application as feed. ie; I dont want to enter any thing in the text box. Instead I had to pass the value from my application which should not be editted and it has to be appear in my wall and the home page of my friends. I even dont require the text box.

Thanks & Regards

Hey Aman, for some reason I keep getting the following errors:

* Method definition for ‘-facebookAgent:dialog:didFailWithError:’ not found

* Class ‘ThirdViewController’ does not fully implement the ‘FacebookAgentDelegate’ protocol

Any help? it looks exactly the same as your sample code test.

Hey Jeff,

I’m not sure if we’re allowed to import text into the edit box, but we can populate information into the message. For example

Say you want to include a user’s text form a textView, then

Depending on where you want to put it, (i.e. caption, etc) remove the @”how are you?” (yes including the @”") and replace it with

[NSString stringWithFormat:@"%@", textView.text]

Hope it helps!

In the login you don’t set the delegate, which means that if they aren’t connected to the Internet there won’t be an appropriate delegate message to – (void)dialog:(FBDialog*)dialog didFailWithError:(NSError*)error;

Simple fix, dialog.delegate = self;

e.g.

- (void) login{
currentAction = FacebookAgentActionLogin;

if(shouldResumeSession){ // try to resume first
if(! [_session resume] ){
if(_session.isConnected){
// Alert already logged in?
}else{
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:_session] autorelease];
dialog.delegate = self;
[dialog show];
}
}
}else {
if(_session.isConnected){
// Alert already logged in?
}else{
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:_session] autorelease];
dialog.delegate = self;
[dialog show];
}
}
}

Your FacebookAgent is just the thing. Will you be extending it further? For example, I wish to create an album by name and load pics there, also to retrieve pics from an album by name. Also, your own getAlbumList is marked TBD. Is there a future and where are you going with this?

After the FacebookAgent integration the posts are shown on the user’s own pinboard but they are not visible for other users when they login. Therefore it has no viral effect. Can anyone explain me why?

How can I close this facebook dialog in my app?
I don’t know why you did hide the button..
How can I show the close icon explicitly in the dialog?

(Thank you for your brilliant source code.!! )

But this code is obsolete now and not maintained anymore.

Please use Facebook Graph api.

Is this still live? Your “obsolete” message is confusing. Is the entire article obsolete? If not, can you provide a link to the sample project?

I followed the method as mentioned in your tutorial and was successfully able to connect to my iPhone in few minutes. It’s quite easy to get around facebook through with my iPhone now.
