Select video from PhotoLibrary in iOS using Swift - ios

Question

I am trying to select video from PhotoLibrary using following code
imageController.mediaTypes = [kUTTypeMovie: NSString]
After selecting video, when it is compressing, I am getting array out of boundary issue.
I searched online and found following line. I am unable to convert it into Swift version (link)
imageController.mediaTypes = [[NSArray alloc] initWithObjects:(NSString *)kUTTypeMovie, nil]
Please let us know the Swift version for above line. It is very useful if anyone can provide Swift version of this.
Question2:
I want to show selected video in app and need to play when it is tapped. Can we do it without external plugins and using built in libraries?

Answer 1

Based on Swift 2.2
Suppose you have a imagePickerController and when you want to select both images and videos:
let imagePickerController = UIImagePickerController()
var videoURL: NSURL?
#IBAction func selectImageFromPhotoLibrary(sender: UIBarButtonItem) {
imagePickerController.sourceType = .PhotoLibrary
imagePickerController.delegate = self
imagePickerController.mediaTypes = ["public.image", "public.movie"]
presentViewController(imagePickerController, animated: true, completion: nil)
}
Then after the video is selected, print out its NSURL.
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
videoURL = info["UIImagePickerControllerReferenceURL"] as? NSURL
print(videoURL)
imagePickerController.dismissViewControllerAnimated(true, completion: nil)
}
For question 2:
Yes, you can do it through AVPlayer, you need import AVKit and AVFoundation, and you code may look like this:
if let videoURL = videoURL{
let player = AVPlayer(URL: videoURL)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
presentViewController(playerViewController, animated: true) {
playerViewController.player!.play()
}
}
I made a demo here you can refer, maybe not 100% what you want.

#IBOutlet weak var imgView: UIImageView!
var imagePickerController = UIImagePickerController()
var videoURL : NSURL?
#IBAction func btnSelectVideo_Action(_ sender: Any) {
imagePickerController.sourceType = .savedPhotosAlbum
imagePickerController.delegate = self
imagePickerController.mediaTypes = [kUTTypeMovie as String]
present(imagePickerController, animated: true, completion: nil)
}
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
videoURL = info[UIImagePickerControllerMediaURL]as? NSURL
print(videoURL!)
do {
let asset = AVURLAsset(url: videoURL as! URL , options: nil)
let imgGenerator = AVAssetImageGenerator(asset: asset)
imgGenerator.appliesPreferredTrackTransform = true
let cgImage = try imgGenerator.copyCGImage(at: CMTimeMake(0, 1), actualTime: nil)
let thumbnail = UIImage(cgImage: cgImage)
imgView.image = thumbnail
} catch let error {
print("*** Error generating thumbnail: \(error.localizedDescription)")
}
self.dismiss(animated: true, completion: nil)
}
For question 2:
let player = AVPlayer(url: videoURL)
let playerController = AVPlayerViewController()
playerController.player = player
self.present(playerController, animated: true) {
player.play()
}

Swift 3
import MobileCoreServices
var imagePickerController = UIImagePickerController()
var videoURL: URL?
private func openImgPicker() {
imagePickerController.sourceType = .savedPhotosAlbum
imagePickerController.delegate = self
imagePickerController.mediaTypes = ["public.movie"]
present(imagePickerController, animated: true, completion: nil)
}
extension YourViewController: UIImagePickerControllerDelegate, UINavigationControllerDelegate {
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) {
videoURL = info[UIImagePickerControllerMediaURL] as? URL
print("videoURL:\(String(describing: videoURL))")
self.dismiss(animated: true, completion: nil)
}
}

func openCamera() {
if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.Camera) {
println("captureVideoPressed and camera available.")
var imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = .Camera
imagePicker.mediaTypes = [kUTTypeMovie!]
imagePicker.allowsEditing = false
imagePicker.showsCameraControls = true
self.presentViewController(imagePicker, animated: true, completion: nil)
} else {
println("Camera not available.")
}
}
func imagePickerController( didFinishPickingMediaWithInfo info:NSDictionary!) {
videoUrl = info[UIImagePickerControllerMediaURL] as! NSURL!
let pathString = videoUrl.relativePath
self.dismissViewControllerAnimated(true, completion: nil)
}

Answer 6

Swift 4.0
Your class adopts the UIImagePickerControllerDelegate protocol
class classname: UIViewController, UIImagePickerControllerDelegate, UINavigationControllerDelegate
After that you need to create
let imagePickerController = UIImagePickerController()
Add this in your button's action:-
imagePickerController.sourceType = .photoLibrary
imagePickerController.delegate = self
imagePickerController.mediaTypes = ["public.image", "public.movie"]
present(imagePickerController, animated: true, completion: nil)
Delegate method
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
let videoURL = info["UIImagePickerControllerReferenceURL"] as? NSURL
print(videoURL!)
imagePickerController.dismiss(animated: true, completion: nil)
}

Let imagePickerController = UIImagePickerController ()
imagePickerController.sourceType = .photoLibrary
imagePickerController.delegate = self
imagePickerController.mediaTypes = ["public.movie"]
present(imagePickerController, animated: true, completion: nil)
// UIImagePickerController Delegate Method
func imagePickerController (_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String: Any])
{
let videoURL = info[UIImagePickerControllerMediaURL] as? NSURL
print(videoURL!)
self.dismiss(animated: true, completion: nil)
}

Answer 8

try this pod that i've made :
https://github.com/jhonyourangel/ImagePickerWhatsApp
I was searching for a similar Image and Video Picker for a project and i wasn't able to find one that was able to :
1. Take picture
2. Get a Picture from the library
3. Register a Video
4. Get a video from the library
While i was looking i hopen whatsup of facebook or mabe google have a pod for this kind of needs, i realy liked the whatsapp picker, so i created this one similer to the one in whatsapp.
Prerequisites
In order to use ImageVideoPicker you need cocoapods and an xCode project already created
Installing
to install cocoapods is should be enough just to run sudo gem install cocoapods in the terminal
if this doen't work go to cocoapods
Then navigate the terminal to your project folder, where the file extension .xcodeproj is located and run pod init
this will create a file called Podfile
Open the file in a editor ( sublimeText, xCode, atom, vim ... etc ) and add the line bellow after use_frameworks!
pod 'ImagePickerWhatsApp'
or
pod 'ImagePickerWhatsApp', :path => '/Users/aiu/Documents/cocoapods/ImagePickerWhatsApp'
then just run pod install in the terminal and wait to finish instaling the lib
How to use it
add import ImagePickerWhatsApp to your viewcontroller class
then you can call the picker by calling :
let mp = ImageVideoPicker.makeVCFromStoryboard()
self.present(mp, animated: true, completion: nil)
Delegate
to implement the delegate add mp.delegate = self and the extent the class of you view controller
aso you need to import the iOS Photos framework import Photos
extension ViewController: ImageVideoPickerDelegate {
func onCancel() {
print("no picture selected")
}
func onDoneSelection(assets: [PHAsset]) {
print("selected \(assets.count) assets")
}
}
the func onDoneSelection returns an array of assets that contain the info of where the asset is located : on the device, iTunes library or iCloud.
if you just need to display the images you can use the this code in a collection view or something similar just implement this peace of code
var representedAssetIdentifier: String!
func getImageFrom(asset: Phasset) {
representedAssetIdentifier = asset?.localIdentifier
let imageManager = PHCachingImageManager()
imageManager.requestImage(for: asset!, targetSize: self.frame.size, contentMode: .default, options: nil) { (image, _) in
if(self.representedAssetIdentifier == self.asset?.localIdentifier &&
image != nil) {
self.imageView.image = image
}
}
}
this will show just the thumbnail, but is awesome because is also showing the thumbnail for live photos, and videos
Images and Videos as Data
The lib is intended to be used for sending images or videos over the network, and not to do fancy image or video editing. But this doesn't mea you can't. You can do just about anything since it returns an array of assets, but is you job to implement what you need.
in order to get the data from the asset ImageVideoPicker has one method that will return an completition handler with the data.
ImageVideoPicker.getDataFrom(asset: asset) { (data) in
if data == nil {
print(data as Any, asset.mediaType, asset.localIdentifier)
} else {
print(data!.count as Any, asset.mediaType, asset.localIdentifier)
}
}
that will be all
have fun

func startMediaBrowserFromViewController(viewController: UIViewController!, usingDelegate delegate : protocol<UINavigationControllerDelegate, UIImagePickerControllerDelegate>!) -> Bool {
if UIImagePickerController.isSourceTypeAvailable(.SavedPhotosAlbum) == false {
return false
}
let mediaUI = UIImagePickerController()
mediaUI.sourceType = .SavedPhotosAlbum
mediaUI.mediaTypes = [kUTTypeMovie as String]
mediaUI.allowsEditing = true
mediaUI.delegate = delegate
presentViewController(mediaUI, animated: true, completion: nil)
return true
}

Answer 10

Updated for the current version of Swift:
// Check if the asset is of video media type.
guard (asset.mediaType == PHAssetMediaType.video) else {
print("Not a valid video media type")
return
}
// Obtain the URL of the video.
PHCachingImageManager().requestAVAsset(forVideo: asset, options: nil, resultHandler: {(asset: AVAsset?, audioMix: AVAudioMix?, info: [AnyHashable : Any]?) in
let asset = asset as! AVURLAsset
print("asset.url: ", asset.url) // Here is video URL
// Play the video.
DispatchQueue.main.async(execute: {
let player = AVPlayer(url: asset.url)
let playerViewController = AVPlayerViewController()
playerViewController.player = player
self.present(playerViewController, animated: true) {
playerViewController.player!.play()
}
})
})

if UIImagePickerController.isSourceTypeAvailable(UIImagePickerControllerSourceType.PhotoLibrary) {
println("Camera Available")
var imagePicker = UIImagePickerController()
imagePicker.delegate = self
imagePicker.sourceType = UIImagePickerControllerSourceType.PhotoLibrary
imagePicker.allowsEditing = false
self.presentViewController(imagePicker, animated: true, completion: nil)
}
Delegate method
func imagePickerController(picker: UIImagePickerController!, didFinishPickingImage image: UIImage!, editingInfo: NSDictionary!) {
self.dismissViewControllerAnimated(true, completion: nil)
imageView.image = image
}
