如何使用按钮点击功能将 [PHAsset] 转换为 Swift 中的 PHAsset

How do you use a button click function to convert an [PHAsset] to PHAsset in Swift

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()
}

谁能解释一下如何将 [PHAsset] 值转换为 PHAsset

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

let phAsset = pickedAssts.first
