ios - NavigationController 中的 Swift ImagePicker
<p><p>所以我在导航 Controller 内，想在按下按钮时显示一个图像选择器。这很好用，但是当我关闭选择器时，它会将我扔回 Root ViewController ，而不是我想要处理图像的地方。</p>
<p>这是我的代码:</p>
<pre><code>@IBAction func attachPhotoButtonPressed(sender: UIButton) {
imagePicker.sourceType = .SavedPhotosAlbum
presentViewController(imagePicker, animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: ) {
if let image = info as? UIImage {
print("Success")
} else{
print("Something went wrong")
}
self.dismissViewControllerAnimated(true, completion: nil)
}
</code></pre>
<p>我已经查看了这些问题，但没有找到解决方法。 (不是 Objective-C 的家伙)</p>

<br><hr><h1><strong>Best Answer-推荐答案</ strong></h1><br>
<p><p>你跳到 Root ViewController 的原因是因为这条线</p>
<p><code>self.dismissViewControllerAnimated(true, completion: nil)</code></p>
<p>正在关闭父 View (自身)，而不是选择器 View 。因此，假设您有对选择器的引用，那么您应该调用 </p>
<p><code>picker.dismissViewControllerAnimated(true, completion: nil)</code></p></p>
