斯威夫特 - 我怎样才能在iPhone上的所有照片和视频的列表？(Swift - How can I

我希望能够查看存储在用户的iPhone照片和视频的列表，以便我可以让他们选择要上传的文件。 到目前为止，我有工作在那里的照片在列表中显示出来，但没有视频被显示出来。 我使用的显示照片库中的代码如下：

@IBAction func btnAddPicOrVideo(sender: AnyObject) {

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

}

正如我所说的，我能够显示照片列表，并选择其中一个就好了。 问题是，我无法看到或选择任何视频。 是否有指定两个图片和视频要显示的方式吗？ 或者，我必须分别显示照片和录像？

我目前正在运行的我在模拟器上的代码，我有一个视频文件存储在本地。

提前致谢。

Answer 1:

我能得到这个指定解析

import MobileCoreServices

和我改变我上面指定为这样的代码：

@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)

}

Answer 2:

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)
        }
    }



}
