Question

我试图在带有iOS 9 beta 4和Swift的iPad上使用popover呈现照片库。首选方法是通过弹出窗口，但UIPopoverController现已弃用。显然它现在通过UIViewController完成，但没有文档，或者我可以找到的示例代码。任何帮助将不胜感激！

谢谢！

Answer 1

上述答案几乎正确，但必须在调用popoverPresentationController之前设置presentViewController()中的锚点：

let myPicker = UIImagePickerController()
myPicker.delegate = self
myPicker.sourceType = .PhotoLibrary
myPicker.modalPresentationStyle = .Popover

let ppc = myPicker.popoverPresentationController
ppc?.barButtonItem = sender as? UIBarButtonItem
ppc?.permittedArrowDirection = .Any

presentViewController(myPicker, animated: true, completion: nil)

Answer 2

我还没有进入图像选择器响应的委托和处理，这篇文章的目的只是考虑使用UIImagePickerController而不使用已弃用的类和方法。

let myPicker = UIImagePickerController()
myPicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary

myPicker.modalPresentationStyle = UIModalPresentationStyle.Popover

self.presentViewController(myPicker, animated: true, completion: nil)

let popper = myPicker.popoverPresentationController
// returns a UIPopoverPresentationController
popper?.barButtonItem = sender as? UIBarButtonItem

请在需要时纠正

在调用imagepicker的函数中简单添加了imagePicker.delegate = self
