Question

我有一个我在xib文件中创建的自定义UIView。现在在另一个视图控制器中，我在故事板中添加了一个滚动视图。在这个视图控制器的实现文件中，我试图添加这个自定义UIView，但它没有显示。我确定我遗失了一些东西，因为我仍然习惯使用xib文件。我尝试添加普通的UIViews，并在滚动视图中正确显示。这是代码：

[[NSBundle mainBundle] loadNibNamed:@"CustomUIView" owner:nil options:nil];
for (int i = 0; i < 10; i++) {
    CustomUIView *setView = [[CustomUIView alloc] initWithFrame:CGRectMake(10, 10 + (10*i) + (i*100), self.view.frame.size.width - 20, 100)];

    [self.scrollView addSubview:setView];
}
self.scrollView.contentSize = CGSizeMake(self.view.frame.size.width, 10 + (10*10) + (10*100));

框架的定位适用于在此循环中以编程方式创建的UIViews，因此我不认为这是问题所在。有任何想法吗？感谢。

使用此代码

use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;

     */
    private function createCreateForm(Pro_profile $entity)
    {
        $form = $this->createForm(new Pro_profileEducationType(), $entity, array(
            'action' => $this->generateUrl('pro_profile_create_education'),
            'method' => 'POST',
        ));

        $form->add('submit', 'submit', array('label' => 'Zakończ rejestracje'));

        return $form;
    }

    /**

     */
    public function educationAction()
    {

        $em = $this->getDoctrine()->getManager();
        $entity = $em->getRepository('MyMainBundle:Pro_profile')->findOneBy(array('user' => $user));

        $form   = $this->createCreateForm($entity);

        return array(
            'entity' => $entity,
            'form'   => $form->createView(),
        );
    }

在您的具体情况下，更好的方法是使UIView成为UITableViewCell并使用它填充UITableView而不是运行循环并在{{1中添加子视图}}。我很高兴它解决了你的问题并同时使你的应用程序更好。

但接近一点，如果你想知道为什么你的代码不工作，问题是你如何加载Nib文件。 This已经回答的问题将清除所有关于加载笔尖的概念，并向您展示以最稳定的方式加载它的正确方法。快乐的编码！
