ios - UIImagePickerController 弹出后 UINavigationBar 消失
<p><p>我有嵌入在 UITabBarController 中的 UIViewController。在我的 <code>PhotoViewController</code> 上，用户可以选择添加照片并调用 <code>UIImagePickerController</code>。用户选择照片并弹出 View 后，导航栏消失。</p>
<p>显示导航栏。</p>

<p>这是 <code>UIImagePickerController</code>View ，它看起来好像 CANCEL 按钮位于 <code>NavigationBar</code> 下方。 (在这张照片中很难看到。)</p>

<p><code>UIImagePickerController</code> 弹出并重新加载 View 后，<code>NavigationBar</code> 消失了。 </p>

<p>这是我如何调用 <code>UIImagePickerController</code>。我继承自 <code>UIImagePickerControllerDelegate</code></p>
<p> <a href="/image/6TwbP.png" rel="noreferrer noopener nofollow"><img src="/image/6TwbP.png" alt="enter image description here"/></a> </p>
<pre><code> UIImagePickerController *imagePickerController = [ init];
imagePickerController.modalPresentationStyle = UIModalPresentationCurrentContext;
imagePickerController.sourceType = sourceType;
imagePickerController.delegate = self;
if (sourceType == UIImagePickerControllerSourceTypeCamera) {
imagePickerController.showsCameraControls = YES;
}
self.imagePickerController = imagePickerController;
;
</code></pre>
<p>虽然代表说不兼容。</p>

<p>如何纠正问题？</p></p>
<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>我加了</p>
<pre><code>imagePickerController.modalPresentationStyle = UIModalPresentationFullScreen;
imagePickerController.modalTransitionStyle = UIModalTransitionStyleCoverVertical;
</code></pre>
<p>这似乎把 imagePickerController 放在了当前 View 的顶部。</p></p>
