ios - 将 [PHAsset] 数组转换为 [UIImage]

Question

有没有办法将 Phasset 数组转换为 UIImage？

var images = [PHAsset]()

func getImages() {
    let assets = PHAsset.fetchAssets(with: PHAssetMediaType.image, options: nil)
    assets.enumerateObjects({ (object, count, stop) in
        // self.cameraAssets.add(object)
        self.images.append(object)
    })

    //In order to get latest image first, we just reverse the array
    self.images.reverse()

在 Swift 4 中将 PHASSET 数组转换为 UIIMAGE

 //MARK: Convert array of PHAsset to UIImages
    func getAssetThumbnail(assets: [PHAsset]) -> [UIImage] {
        var arrayOfImages = [UIImage]()
        for asset in assets {
            let manager = PHImageManager.default()
            let option = PHImageRequestOptions()
            var image = UIImage()
            option.isSynchronous = true
            manager.requestImage(for: asset, targetSize: CGSize(width: 100, height: 100), contentMode: .aspectFit, options: option, resultHandler: {(result, info)->Void in
                image = result!
                arrayOfImages.append(image)
            })
        }

        return arrayOfImages
    }
