Answer 3

add FBConnect into your project and use below code for share capture image on facebook. Also add delegate FBSessionDelegate, FBDialogDelegate, FBRequestDelegate into your .h file. If you want to share local image than you don't need to upload image on server. pass uiimage object into facebook params.

if (facebook == nil) {
        facebook = [[Facebook alloc] initWithAppId:@"your facebook key "];


    }   


    NSArray* permissions =  [NSArray arrayWithObjects:
                             @"publish_stream", @"offline_access", nil] ;
    //  
    [facebook authorize:permissions delegate:self];

- (BOOL) takeScreenshot
{
    UIGraphicsBeginImageContext(self.view.frame.size);
    [self.view.layer renderInContext:UIGraphicsGetCurrentContext()];
    UIImage *viewImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();
    UIImageWriteToSavedPhotosAlbum(viewImage, nil, nil, nil);



    NSMutableDictionary* params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   viewImage,@"message",                                   
                                   nil];

    [facebook requestWithGraphPath:@"me/photos"   // or use page ID instead of 'me'
                         andParams:params
                     andHttpMethod:@"POST"
                       andDelegate:self];



    return YES;
}

#pragma mark FBSessionDelegate
/**

- (void)fbDidLogin {
    isFBLogged = YES;   
    [self takeScreenshot];

    if([self takeScreenshot])
    {
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle: @"Image share sucessfully"
                              message: nil
                              delegate: nil
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
    else
    {
        UIAlertView *alert = [[UIAlertView alloc]
                              initWithTitle: @"Image share unsucessfully"
                              message: nil
                              delegate: nil
                              cancelButtonTitle:@"OK"
                              otherButtonTitles:nil];
        [alert show];
        [alert release];
    }
