将facebook profilePicture，profileId传递给profileViewController。

Question

我已经能够将user.name facebook属性传递给profileViewController。

但是我无法发送FBProfilePicture，虽然这里有以下方法：

// this method will be called when the user information has been fetched
- (void)loginViewFetchedUserInfo:(FBLoginView *)loginView user:(id<FBGraphUser>)user
{
    FBProfilePicture.profileID = user.id;
    FBNamePass = user.name;
    [self pushViewController:FBNamePass andProfilePicture:FBProfilePicture];
}

以及方法：

- (void)pushViewController:(NSString *)user andProfilePicture:(FBProfilePictureView *)profilePicture
{
    NeXtViewController *controller = [self.storyboard instantiateViewControllerWithIdentifier:@"NeXt"];
    controller.FBNameString = user;
    //controller.profilePicture.profileID = profilePicture.profileID;
    [controller setFBProfilePicture:profilePicture];
    [self.navigationController pushViewController:controller animated:NO];
}

我有什么问题吗？

似乎首先需要初始化对象，然后才为它设置属性：

FBProfilePicture = [[FBProfilePictureClass alloc] init];
FBProfilePicture.profileID = user.id;
