Wie kann ich Bilder mit der NohanaImagePicker Pod-Datei sehen?

Question

Ich bin mit schnellen 3 und verwende NohanaImagePickerpod Datei mehr Bilder auszuwählen und sein Arbeits gut das Problem ist, dass ich ausgewählt Bilder in der Sammlung Ansicht sehen will, und ich werde in dieser Linie

 cell.imageforCV.image = ViewController.imgArray[indexPath.row] 

I fatal Fehler erhalten verwendet statische Variante für imgArray

hier ist mein Codes

import UIKit 
import Photos 
import NohanaImagePicker 

class ViewController: UIViewController , NohanaImagePickerControllerDelegate , UICollectionViewDelegate , UICollectionViewDataSource { 

static var imgArray = [UIImage]() 
static var imgCount = Int() 
@IBOutlet weak var imageCollectionView: UICollectionView! 
var images = [ PHAsset]() 
@IBAction func gallery(_ sender: UIButton) { 

let picker = NohanaImagePickerController() 
    picker.delegate = self 
    present(picker, animated: true, completion: nil) 
    picker.maximumNumberOfSelection = 200 
    print("\(picker)") 


} 
func nohanaImagePickerDidCancel(_ picker: NohanaImagePickerController) { 
    print("Canceled") 
    picker.dismiss(animated: true, completion: nil) 
} 

    func nohanaImagePicker(_ picker: NohanaImagePickerController, didFinishPickingPhotoKitAssets pickedAssts :[PHAsset]) { 
    print("Completed\n\tpickedAssets = \(pickedAssts)") 
    picker.dismiss(animated: true, completion: nil) 
    performSegue(withIdentifier: "back", sender: self) 
    let numberOfImages = pickedAssts.count 
    print("\(numberOfImages)") 


    ViewController.imgCount = pickedAssts.count 

    var phAssetArray : [PHAsset] = [] 

    for i in 0..<pickedAssts.count 
    { 
     ViewController.imgArray.append(self.getAssetThumbnail(asset: pickedAssts[i])); 
    } 
    let size = CGSize(width: 50, height: 50) 
    let options = PHImageRequestOptions() 

    let manager : PHCachingImageManager = PHCachingImageManager() 


    manager.startCachingImages(for: phAssetArray, 
                targetSize: size, 
                contentMode: .aspectFill, 
                options: options) 

    imageCollectionView.reloadData() 
       } 


func getAssetThumbnail(asset: PHAsset) -> UIImage { 
    var retimage = UIImage() 
    print(retimage) 
    let manager = PHImageManager.default() 
    manager.requestImage(for: asset, targetSize: CGSize(width: 50.0, height: 50.0), contentMode: .aspectFit, options: nil, resultHandler: {(result, info)->Void in 
     retimage = result! 
    }) 
    print(retimage) 
    return retimage 
} 

func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int { 
    return ViewController.imgArray.count 
} 


func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell { 
    let cell = imageCollectionView.dequeueReusableCell(withReuseIdentifier: "imageCell", for: indexPath) as! imageCell 

    print(ViewController.imgArray.count) 
    print(indexPath.row) 
    print(ViewController.imgArray[indexPath.row]) 



    cell.imageforCV.image = ViewController.imgArray[indexPath.row] 

    return cell 

} 


    override func viewDidLoad() { 
     super.viewDidLoad() 

     imageCollectionView.reloadData() 

     self.imageCollectionView!.dataSource = self 
     self.imageCollectionView!.delegate = self 


    let picker = NohanaImagePickerController() 

    // Set the maximum number of selectable images 

    // Set the cell size 
    picker.numberOfColumnsInPortrait = 2 
    picker.numberOfColumnsInLandscape = 3 

    // Show Moment 
    picker.shouldShowMoment = true 

    // Show empty albums 
    //  picker.shouldShowMoment = shouldShowEmptyAlbum = true 

    // Hide toolbar 
    picker.shouldShowEmptyAlbum = true 

    // Disable to pick asset 
    picker.canPickAsset = { (asset:Asset) -> Bool in 
     return false 
    } 

    // Color 
    ColorConfig.backgroundColor = UIColor.white 
    } 

Answer 1

Verwendung folgende Funktion

func getAssetThumbnail(asset: PHAsset) -> UIImage { 
    let manager = PHImageManager.default() 
    let option = PHImageRequestOptions() 
    var thumbnail = UIImage() 
    option.version = .original 
    option.isSynchronous = true 
    manager.requestImage(for: asset, targetSize: CGSize(width: 100, height: 100), contentMode: .aspectFit, options: option, resultHandler: {(result, info)->Void in thumbnail = result! }) 
    return thumbnail 
} 

Werfen wir zunächst Vermögenswert als

let phAsset = pickedAssts.first
