Ios 从DKAssests获取所选图像

使用DKImagePickerController从gallery中选择多个图像和视频。但只能从gallery中选择图像和视频，但无法从DKAssets中获取所选图像并保存到阵列。花了一天多的时间

下面是正在尝试的代码：

let pickerController = DKImagePickerController()


        pickerController.assetType = DKImagePickerControllerAssetType.AllAssets
        pickerController.allowsLandscape = false
        pickerController.allowMultipleTypes = true
        pickerController.sourceType = DKImagePickerControllerSourceType.Both
        pickerController.singleSelect = false

        // Clear all the selected assets if you used the picker controller as a single instance.
        //      pickerController.defaultSelectedAssets = nil

        pickerController.defaultSelectedAssets = self.assets

        pickerController.didSelectAssets = { [unowned self] (assets: [DKAsset]) in
            print("didSelectAssets")


    }
    self.presentViewController(pickerController, animated: true) {}

请引导，谢谢ion advance。

尝试此功能。这对我有用

func showImagePickerWithAssetType
    (
    assetType: DKImagePickerControllerAssetType,
    allowMultipleType: Bool,
    sourceType: DKImagePickerControllerSourceType = [.Camera, .Photo],
    allowsLandscape: Bool,
    singleSelect: Bool) {

        let pickerController = DKImagePickerController()
        pickerController.assetType = assetType
        pickerController.allowsLandscape = allowsLandscape
        pickerController.allowMultipleTypes = allowMultipleType
        pickerController.sourceType = sourceType
        pickerController.singleSelect = singleSelect
        //          pickerController.showsCancelButton = true
        //          pickerController.showsEmptyAlbums = false
        //          pickerController.defaultAssetGroup = PHAssetCollectionSubtype.SmartAlbumFavorites

        // Clear all the selected assets if you used the picker controller as a single instance.
        //          pickerController.defaultSelectedAssets = nil
        pickerController.defaultSelectedAssets = self.assets

        pickerController.didSelectAssets = { (assets: [DKAsset]) in
            print("didSelectAssets")

            self.assets = assets
            if assets.count > 0 {
                self.cameramoment.titleLabel?.textColor = UIColor.redColor()
                //self.cameramoment.titleLabel?.alpha = 50
                //self.cameramoment.titleLabel?.textColor = UIColor(red: 0.0, green: 184.0, blue: 214.0, alpha: 1.0)
            }
            else {
                //self.cameramoment.setImage( UIImage (named: "grey_camera_32x32"), forState: .Normal)
              self.cameramoment.titleLabel?.textColor = UIColor.lightGrayColor()
              self.cameramoment.titleLabel?.alpha = 50
            }
            self.collectionview.reloadData()

        }

        if UI_USER_INTERFACE_IDIOM() == .Pad {
            pickerController.modalPresentationStyle = .FormSheet;
        }

        self.presentViewController(pickerController, animated: true) {}
}

像这样调用这个函数

self.showImagePickerWithAssetType(DKImagePickerControllerAssetType.AllPhotos, allowMultipleType: true, allowsLandscape: true, singleSelect: false)

自我资产定义为：

var assets: [DKAsset] = []

从DKAsset获取图像。试试这个

for asset in assets {
  asset.fetchImageWithSize(requiredImageSize, completeBlock: { image, info in
            if let img = image {
              let fixOrientationImage=img.fixOrientation()
              cell.postmomentimage1.image = fixOrientationImage
            }
    })
}
