Try this :-
1.>First setup your application on facebook by following Facebook url.
2.> Then use this code and modify according to your requirments.
-(void)inviteFriends
{
if ([[FBSession activeSession] isOpen])
{
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:nil];
[FBWebDialogs presentRequestsDialogModallyWithSession:nil
message:@"put your message here"
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];
}
}];
}
}
Please check your app check permission. If permission not assign then please assign permissions whatever you want in your app
NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:/*assign permission here*/ nil];
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];
}
- (void)requestFailedWithError:(NSError *)error
{
if(error == nil)
CCLOG(@"user cancelled");
else
CCLOG(@"failed");
}
i hope it helps you.
