Dear Author, can I get the special ratio with NSPredicate ?

[brandy2015]

let options = PHFetchOptions()
options.predicate = NSPredicate(format: "pixelHeight / pixelWidth == %d", 2)
configure.fetchOption = options

It doesn't work.

Wanna get 1:2 pixelHeight : pixelWidth

[brandy2015]

func canSelectAsset(phAsset: PHAsset) -> Bool {
if (phAsset.pixelWidth / phAsset.pixelHeight) == 2 || (Double(phAsset.pixelWidth) / Double(phAsset.pixelHeight)) == 0.5{
return true
}
}

it's not enough
