如何使用按钮单击函数在Swift中将[ PHAsset ]转换为PHAsset

Question

public func nohanaImagePicker(_ picker: NohanaImagePickerController, didFinishPickingPhotoKitAssets pickedAssts: [PHAsset])
{
    print("Completed\n\tpickedAssets = \(pickedAssts)")
    self.getAssetThumbnail(asset: pickedAssts)
    picker.dismiss(animated: true, completion: nil)
    self.ImageCollectionView.reloadData()
}

任何人都可以解释如何将PHAsset值转换为PHAsset

Answer 1

[PHAsset]是PHAsset对象的数组。您可以像这样选择数组的第一个对象。

let phAsset = pickedAssts.first
