问题
I would like to be able to view a list of both photos and videos stored on the user's iPhone so I can allow them to select the file for upload. So far, I have it working where photos show up in the list, but no videos are showing up. The code I'm using to display the photos library is the following:
@IBAction func btnAddPicOrVideo(sender: AnyObject) {
let pickerC = UIImagePickerController()
pickerC.delegate = self
self.presentViewController(pickerC, animated: true, completion: nil)
}
As I mentioned, I'm able to display a list of photos and select one of them just fine. The problem is that I'm unable to see or select any videos. Is there a way to specify for both pictures and videos to be displayed? Or, do I have to display pictures and videos separately?
I'm currently running my code on the simulator and I have a video file stored on it locally.
Thanks in advance.
回答1:
I was able to get this resolved by specifying
import MobileCoreServices
and I changed the code I specified above as such:
@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)
}
}
}
