presentRequestsDialogModallyWithSession does not work, but gives good result - api

Question

When I use the webdialog for a friendrequest, everything is going fine, except no request or anything is made.
The code:
NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
facebookFriend.id, #"to",
nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:FBSession.activeSession
message:NSLocalizedString(#"FB_FRIEND_INVITE_MESSAGE", #"Facebook friend invite message")
title:NSLocalizedString(#"FB_FRIEND_INVITE_TITLE", #"Facebook friend invite title")
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error) {
}];
This is the result I get:
fbconnect://success?request=xxxxxxxxxxxx&to%5B0%5D=xxxxxxxx
How can I debug what is going wrong?
Thanks in advance.

For SDK 3.2 or above we have a facility to use FBWebDialogs class that will help us to show a popup along with the friend list and pick one or more from list to send invitation.
Lets do it step by step:
1) Download and setup SDK 3.2 or above.
2) First setup your application on facebook by following this url.
3) Then use the attached code.
Sample Code: (It generates invite friend request)
-(void)inviteFriends
{
if ([[FBSession activeSession] isOpen])
{
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:[self getInviteFriendMessage]
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
[self requestFailedWithError:error];
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
[self requestFailedWithError:nil];
}
else if([[resultURL description] hasPrefix:#"fbconnect://success?request="])
{
// Facebook returns FBWebDialogResultDialogCompleted even user
// presses "Cancel" button, so we differentiate it on the basis of
// url value, since it returns "Request" when we ACTUALLY
// completes Dialog
[self requestSucceeded];
}
else
{
// User Cancelled the dialog
[self requestFailedWithError:nil];
}
}
}
];
}
else
{
/*
* open a new session with publish permission
*/
[FBSession openActiveSessionWithPublishPermissions:[NSArray arrayWithObject:#"publish_stream"]
defaultAudience:FBSessionDefaultAudienceFriends
allowLoginUI:YES
completionHandler:^(FBSession *session, FBSessionState status, NSError *error)
{
if (!error && status == FBSessionStateOpen)
{
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:[self getInviteFriendMessage]
title:nil
parameters:params
handler:^(FBWebDialogResult result, NSURL *resultURL, NSError *error)
{
if (error)
{
[self requestFailedWithError:error];
}
else
{
if (result == FBWebDialogResultDialogNotCompleted)
{
[self requestFailedWithError:nil];
}
else if([[resultURL description] hasPrefix:#"fbconnect://success?request="])
{
// Facebook returns FBWebDialogResultDialogCompleted even user
// presses "Cancel" button, so we differentiate it on the basis of
// url value, since it returns "Request" when we ACTUALLY
// completes Dialog
[self requestSucceeded];
}
else
{
// User Cancelled the dialog
[self requestFailedWithError:nil];
}
}
}];
}
else
{
[self requestFailedWithError:error];
}
}];
}
}
and here are the helper functions that calls delegates function OnFBSuccess and OnFBFailed.
- (void)requestSucceeded
{
NSLog(#"requestSucceeded");
id owner = [fbDelegate class];
SEL selector = NSSelectorFromString(#"OnFBSuccess");
NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];
_callback = [NSInvocation invocationWithMethodSignature:sig];
[_callback setTarget:owner];
[_callback setSelector:selector];
[_callback retain];
[_callback invokeWithTarget:fbDelegate];
}
- (void)requestFailedWithError:(NSError *)error
{
NSLog(#"requestFailed");
id owner = [fbDelegate class];
SEL selector = NSSelectorFromString(#"OnFBFailed:");
NSMethodSignature *sig = [owner instanceMethodSignatureForSelector:selector];
_callback = [NSInvocation invocationWithMethodSignature:sig];
[_callback setTarget:owner];
[_callback setSelector:selector];
[_callback setArgument:&error atIndex:2];
[_callback retain];
[_callback invokeWithTarget:fbDelegate];
}
So the class taht calls method InviteFriend MUST have these functions:
-(void)OnFBSuccess
{
CCLOG(#"successful");
// do stuff here
[login release];
}
-(void)OnFBFailed:(NSError *)error
{
if(error == nil)
CCLOG(#"user cancelled");
else
CCLOG(#"failed");
// do stuff here
[login release];
}

An Example
NOTE:
1) Don't forget to setup Facebook application ID in plist.
2) Don't forget to adjust AppDelegate to handle urls.
Partial snippet taken from above link in point 2:
/*
* If we have a valid session at the time of openURL call, we handle
* Facebook transitions by passing the url argument to handleOpenURL
*/
- (BOOL)application:(UIApplication *)application
openURL:(NSURL *)url
sourceApplication:(NSString *)sourceApplication
annotation:(id)annotation {
// attempt to extract a token from the url
return [FBSession.activeSession handleOpenURL:url];
}
Hope it helps!
EDIT
Here:
declaration for fbDelegate is:
#property (nonatomic, assign) id <FBLoginDelegate> fbDelegate;
#protocol FBLoginDelegate <NSObject>
#required
-(void) OnFBSuccess;
-(void) OnFBFailed : (NSError *)error;
#end
and this is how you can consume this code:
FBLoginHandler *login = [[FBLoginHandler alloc] initWithDelegate:self]; // here 'self' is the fbDelegate you have asked about
[login inviteFriends];

I think your application is not enable for Android and for web . And you are trying to get notification on web or on Android device.
Points : For getting notification on Android or on web you have to enable your app for Android and web too .
To Enable Android and Web on your App : GoTo your App > Setting > Click on + Add platform add enter necessary information and Save .
Lets Enjoy Notification . :-)
