Try with this I used Facebook SDK 3.1 https://developers.facebook.com/ios/
.h file
#import <FacebookSDK/FacebookSDK.h>
extern NSString *const SCSessionStateChangedNotificationCamera;
.m file
NSString *const SCSessionStateChangedNotificationCamera = #"com.facebook.Scrumptious:SCSessionStateChangedNotification";
-(IBAction)btnFacebookShareClick:(id)sender {
if (![self openSessionWithAllowLoginUI:YES]) {
[self showLoginView];
}
}
#pragma mark -
#pragma mark - Facebook Method
- (void) performPublishAction:(void (^)(void)) action {
if ([FBSession.activeSession.permissions indexOfObject:#"publish_actions"] == NSNotFound) {
[FBSession.activeSession reauthorizeWithPublishPermissions:[NSArray arrayWithObject:#"publish_actions"] defaultAudience:FBSessionDefaultAudienceFriends completionHandler:^(FBSession *session, NSError *error) {
if (!error) {
action();
}
}];
}
else {
action();
}
}
