Getting size (height and width) from PHAsset

Question

Is there a way to get the height and width of the image from a PHAsset object.

I'm trying to make an image picker with a custom UICollectionViewLayout (Kind of like the main page of Pinterest app) I'v fetched all of the photos from the photo library into an array as PHAsset objects. But I need to get the size of the image from the PHAsset object for the delegate method collectionView:layout:sizeForItemAtIndexPath:

Is there a fast way to achieve this?

Answer 1

PHAsset具有pixelWidth和pixelHeight属性。

Answer 2

You can get them using this.

let imgheight = yourAsset.pixelHeight
let imgwidth = yourAsset.pixelWidth
