Swift-如何獲取iPhone上所有照片和視頻的列表？

Question

我希望能夠查看用戶iPhone上存儲的照片和視頻的列表，以便允許他們選擇要上傳的文件。 到目前為止，我可以在列表中顯示照片的地方使用它，但是沒有視頻顯示。 我用來顯示照片庫的代碼如下：

@IBAction func btnAddPicOrVideo(sender: AnyObject) {

    let pickerC = UIImagePickerController()        
    pickerC.delegate = self        
    self.presentViewController(pickerC, animated: true, completion: nil)

}

如前所述，我可以顯示一張照片列表，然后選擇其中一張就可以了。 問題是我無法觀看或選擇任何視頻。 有沒有辦法指定要顯示的圖片和視頻？ 還是我必須分別顯示圖片和視頻？

我目前正在模擬器上運行代碼，並且在本地存儲了一個視頻文件。

提前致謝。

Answer 1

我可以通過指定解決此問題

import MobileCoreServices

我將上面指定的代碼更改為：

@IBAction func btnAddPicOrVideo(sender: AnyObject) {

    let pickerC = UIImagePickerController()        
    pickerC.mediaTypes = [kUTTypeImage as NSString, kUTTypeMovie as NSString]
    pickerC.delegate = self        
    self.presentViewController(pickerC, animated: true, completion: nil)

}

class ScoutDetailPage: UIViewController,UIImagePickerControllerDelegate {

var picker:UIImagePickerController? = UIImagePickerController()
let imageView = UIImageView ()
{

override func viewDidLoad(){

        // Do any additional setup after loading the view.

self.loadOrTakePhotos()

}

func loadOrTakePhotos()

{

if(UIImagePickerController .isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera))
    {
picker!.sourceType = UIImagePickerControllerSourceType.Camera
        picker?.delegate = self

self .presentViewController(picker!, animated: true, completion: nil)
            }

        }
        else if (pickersegment.selectedSegmentIndex == 1)
        {
            picker!.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
            picker?.delegate = self

          self.presentViewController(picker!, animated: true, completion: nil)

        }
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [NSObject : AnyObject]) {
 let pickedimage = info[UIImagePickerControllerOriginalImage] as! UIImage

imageView.image = pickedimage
            if (imageView.image != nil)
            {
                print("image not empty")

// Do something here.

picker .dismissViewControllerAnimated(false, completion: nil)

            }
            else
            {
                print("IMAGE VIEW NIL")
            }
        }

    func image(image: UIImage, didFinishSavingWithError error: NSErrorPointer, contextInfo:UnsafePointer<Void>) {

        if error != nil {
            let alert = UIAlertController(title: "Save Failed",
                message: "Failed to save image",
                preferredStyle: UIAlertControllerStyle.Alert)

            let cancelAction = UIAlertAction(title: "OK",
                style: .Cancel, handler: nil)

            alert.addAction(cancelAction)
            self.presentViewController(alert, animated: true,
                completion: nil)
        }
    }
