I am new to iphone development, i want to display the permission page after logging facebook.
buttonIndex is the index of my actionsheets.
if(buttonIndex == 1)
{
session = [FBSession sessionForApplication:#"My App key" secret:#"My Key" delegate:self];
FBLoginDialog* dialog = [[[FBLoginDialog alloc] initWithSession:session] autorelease];
[dialog show];
}
by using those code successfully loggin to facebook, but i want to permission page to display,
so i can use,
- (void)session:(FBSession*)session didLogin:(FBUID)uid
{
NSLog(#"User with id %lld logged in.", uid);
FBPermissionDialog* dialog1 = [[[FBPermissionDialog alloc] init] autorelease];
dialog1.delegate = self;
dialog1.permission = #"uid";
[dialog1 show];
}
But its not working. Where can i put that code.
And I want to share my content after the permission allowed.
If i logout the facebook, it goes to the browser but i want to return my application after logout,
Please help me out, guide me plz.
I would change this dialog1.permission = #"uid"; to something like this
dialog1.permission = #"publish_stream";. Because you want to publish your content to the users stream, right?
- (void)session:(FBSession*)session didLogin:(FBUID)uid
After loggin in I would first check if you might already have the permission to publish to the user's stream, by creating a FBRequest
NSDictionary *params = [NSDictionary dictionaryWithObjectsAndKeys: #"publish_stream", #"ext_perm", nil];
[[FBRequest requestWithDelegate:self] call:#"facebook.users.hasAppPermission" params:params];
The result you can evaluate here
- (void)request:(FBRequest*)request didLoad:(id)result
e.g. like this
if ([request.method isEqualToString:#"facebook.users.hasAppPermission"])
{
NSString *success = result;
if ([success isEqualToString:#"1"])
{
NSLog(#"User has app permission");
// publish content now
...
}
else
{ // else ask for permission, opening permission dialog
...
}
I highly recommend this guy's tutorial, Brandon Treb, on integrating Facebook. He does a very thorough presentation and takes you line-by-line, so if it does not work, its a typo on your part. His tutorial got me up and running in less than two hours.

I am working on Facebook integration and trying for Single Sign-On with publish feed functionality.
I am using latest FacebookSDK. I have Facebook's Hackbook example code but, i am new to all this so it is being difficult to understand completely all this things.
While searching on SSO i got some code, It is working fine. Here is the code i am using (At the end of this page there is a source code attached)
FBUtils.h and FBUtils.m class
ViewController.m
- (IBAction)publishFeed:(id)sender {
//For SSO
[[FBUtils sharedFBUtils] initializeWithAppID:#"3804765878798776"];
NSArray *permision = [NSArray arrayWithObjects:#"read_stream",#"publish_stream", nil];
[[FBUtils sharedFBUtils] LoginWithPermisions:permision];
[FBUtils sharedFBUtils].delegate = self;
FBSBJSON *jsonWriter = [FBSBJSON new];
/// for publishfeed
NSArray* actionLinks = [NSArray arrayWithObjects:[NSDictionary dictionaryWithObjectsAndKeys:
#"Get Started",#"name",#"https://itunes.apple.com?ls=1&mt=8",#"link", nil], nil];
NSString *actionLinksStr = [jsonWriter stringWithObject:actionLinks];
// Dialog parameters
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
#"I have lot of fun preparing.", #"name",
#" exam", #"caption",
#" ", #"description",
#"https://itunes.apple.com", #"link",
#"http://mypng", #"picture",
actionLinksStr, #"actions",
nil];
AppDelegate *delegate = (AppDelegate *)[[UIApplication sharedApplication] delegate];
[[delegate facebook] dialog:#"feed"
andParams:params
andDelegate:self];
When i tap Facebook button in my app it is redirect me to Facebook and then retuning back to my app. Now , what i want is to fire publishFeed event right after returning back to the app and it should ask direct for post or cancel options to the user. But it is asking for login again like this.
Can any one help me in this or please suggest me the right way.
Your Suggestions would be a great help.
In your method, you're not checking if the app has permissions to publish post and if the user logged in before. So, every time you call this method, the app wants you to login. I think that is the problem.
If I'm right, you need to add permission and login control in your method like this. This is my sample code from another project, you can get the logic behind it.
- (IBAction)facebookShare:(id)sender
{
AppDelegate *appDelegate = [[UIApplication sharedApplication] delegate];
// You check the active session here.
if (FBSession.activeSession.isOpen)
{
// You check the permissions here.
if ([FBSession.activeSession.permissions
indexOfObject:#"publish_actions"] == NSNotFound) {
// No permissions found in session, ask for it
[FBSession.activeSession
reauthorizeWithPublishPermissions:
[NSArray arrayWithObject:#"publish_actions"]
defaultAudience:FBSessionDefaultAudienceFriends
completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
// If permissions granted, publish the story
[self postFacebook];
[[[UIAlertView alloc] initWithTitle:#"Result"
message:#"Posted in your wall."
delegate:self
cancelButtonTitle:#"OK"
otherButtonTitles:nil]
show];
}
}];
} else {
// If permissions present, publish the story
[self postFacebook]; // ------> This is your post method.
[[[UIAlertView alloc] initWithTitle:#"Sonuç"
message:#"Duvarında paylaşıldı."
delegate:self
cancelButtonTitle:#"Tamam"
otherButtonTitles:nil]
show];
}
}
else
{
// If there is no session, ask for it.
[appDelegate openSessionWithAllowLoginUI:YES];
}
// NSLog(#"Post complete.");
}
hello i have a app that connects and post to user wall but when i try to post it always open the persmission page and in that page it writes you already give permission to this app.I want it to come only 1 time can anyone help me to do that?
- (id)init {
if (self == [super init]) {
facebook = [[Facebook alloc] initWithAppId:kAppId];
facebook.sessionDelegate = self;
if(permissions==nil){
permissions = [[NSArray arrayWithObjects:
#"read_stream", #"user_birthday",
#"publish_stream", nil] retain];
}
[self login];
}
return self;
}
- (void)login {
if (![_session isConnected]) {
[self postToWall];
}
// only authorize if the access token isn't valid
// if it *is* valid, no need to authenticate. just move on
if (![facebook isSessionValid]) {
[facebook authorize:permissions delegate:self];
}
is it because i init method?
See this page - https://developers.facebook.com/docs/guides/mobile/. Basically what you want to do is save the authentication information (access_token) when the user is authorized, then next time you can check for the saved values and skip the authentication.
I successfully integrate the face-book API and able to get all user profile but the problem is the value i am getting without permission dialog. In place of permission dialog i am getting blank white dialog without any content or any buttons.I am using FBConnect.
I Done with this code i stuck from last many days because i am not able to find the reason also i tried google to get solution but not get success.
My code is here to display dialog.
`-(void)askPermission:(id)target{
FBPermissionDialog* dialog = [[[FBPermissionDialog alloc] init]
autorelease];
//dialog.permission = [NSString stringWithString: #"user_birthday,user_interests"];
dialog.delegate = self;
dialog.permission = #"user_interests,user_birthday";
[dialog show];
}`
in FBPermissionDialog.m
-(BOOL)webView:(UIWebView *)webView shouldStartLoadWithRequest:(NSURLRequest *)request
navigationType:(UIWebViewNavigationType)navigationType {
// if (_permission = [NSString stringWithFormat:#"user_interests"]);
// {
// NSURL* url = request.URL;
// if ([url.scheme isEqualToString:#"fbconnect"]) {
// if ([url.resourceSpecifier isEqualToString:#"success"]) {
// [self redirectToLogin];
// return NO;
// }
//}
return [super webView:webView shouldStartLoadWithRequest:request navigationType:navigationType];
}
-(void)dialogDidSucceed:(FBDialog*)dialog {
NSString* fql = [NSString stringWithFormat:
#"select name, first_name, last_name, hometown_location, sex, pic_square, current_location, interests, birthday_date , activities, tv, movies, music, books from user where uid == %lld", _session.uid];
NSLog(#"%#",fql);
NSDictionary* params = [NSDictionary dictionaryWithObject:fql forKey:#"query"];
NSLog(#"%#",params);
[[FBRequest requestWithDelegate:self] call:#"facebook.fql.query" params:params];
}
Please help me i don't know why i didn't get the permission Dialog and getting blank screen .Any help will be appreciated.
Thank You
meaning you are not getting the login credential dialogue. Is there any dialog appearing BUT its blank? If yes please make sure you have the latest Facebook for IOS sdk downloaded please :) Link : https://github.com/facebook/facebook-ios-sdk
I know - I have read the documentation - but frankly Facebook is horrible at it. I can't figure out how to send a request that illicits a response. Here's what I'm trying:
NSURL *fbID = [NSURL URLWithString:#"https://graph.facebook.com/me?fields=id"];
fbUserID = [[NSData alloc] initWithContentsOfURL: fbID];
Where should this code go? Is there a specific class it is looking for if I have set 'self' as delegate?
How are you trying to integrate FB into your app? I have been looking into Facebook connect recently and found their documentation very helpful (http://developers.facebook.com/docs/guides/mobile/#ios). I know you said you looked at the documentation, but for me after going through their steps for iOS I was able to make an app that allowed users to sign in and give me access to their basic information, including ID. After going through authorization, I had the following code in my app delegate:
- (void) fbDidLogin {
//get information about the currently logged in user
[facebook requestWithGraphPath:#"me" andDelegate:self];
}
- (void)request:(FBRequest *)request didLoad:(id)result {
NSString *name = [result objectForKey:#"name"];
NSString *msg = [[NSString alloc] initWithFormat:#"To prove this works, your name is %#",name];
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:#"Thanks for Logging In!"
message:msg
delegate:nil
cancelButtonTitle:#"OK"
otherButtonTitles:nil];
[alert show];
[alert release];
}
This gets the user's full name after logging in and displays it. You can do the same thing for getting their ID.
This all is driving me nuts.
I just integrated facebook in my iphone app.
After typing in my username and password in the login dialog this method is called.
- (void)request:(FBRequest*)request didLoad:(id)result {
if ([request.method isEqualToString:#"facebook.fql.query"]) {
NSLog(#"result %#",result);
NSArray* users = result;
NSLog(#"users %#",users);
NSDictionary* user = [users objectAtIndex:0];
NSString* name = [user objectForKey:#"name"];
self.facebookName = name;
if (_posting) {
[self postToWall];
_posting = NO;
}
}
}
But after this the app crashes most of the times and when I tried to log the "result" array it appears to be empty. Why is it so?
What should I do? Please suggest.
use this code
NSArray *users=[[NSArray alloc]initWithObjects:result, nil];
NSLog(#"users %#",users);
NSDictionary* user = [[NSDictionary alloc]initWithObjectsAndKeys:users,#"users", nil];
NSLog(#"%#",user);
I got the reason for this.
This was due to the session getting lost frequently in between.
So I had to call [session resume] in the facebook login action event
and in this manner if at all the session is lost by any chance then the previous session is resumed and the "result" does not appears to be nil in (void)request:(FBRequest*)request didLoad:(id)result method.
Hope this helps out those who are stuck in the same issue.
