I'm attempting to create a UIImage (like a thumbnail or something) from a PHAsset so that I can pass it into something that takes a UIImage. I've tried adapting solutions I found on SO (since they all just directly pass it into say a tableview or something), but I have no success (likely because I'm not doing it right).
func getAssetThumbnail(asset: PHAsset) -> UIImage {
var retimage = UIImage()
println(retimage)
let manager = PHImageManager.defaultManager()
manager.requestImageForAsset(asset, targetSize: CGSize(width: 100.0, height: 100.0), contentMode: .AspectFit, options: nil, resultHandler: {(result, info)->Void in
retimage = result
})
println(retimage)
return retimage
}
The printlns are telling me that the manager.request line isn't doing anything right now. How do I get it to give me the asset as a UIImage.
Thanks.
This did what I needed it to do, in case anyone also needs this.
func getAssetThumbnail(asset: PHAsset) -> UIImage {
let manager = PHImageManager.defaultManager()
let option = PHImageRequestOptions()
var thumbnail = UIImage()
option.synchronous = true
manager.requestImageForAsset(asset, targetSize: CGSize(width: 100.0, height: 100.0), contentMode: .AspectFit, options: option, resultHandler: {(result, info)->Void in
thumbnail = result!
})
return thumbnail
}
func getAssetThumbnail(asset: PHAsset) -> UIImage {
let manager = PHImageManager.default()
let option = PHImageRequestOptions()
var thumbnail = UIImage()
option.isSynchronous = true
manager.requestImage(for: asset, targetSize: CGSize(width: 100, height: 100), contentMode: .aspectFit, options: option, resultHandler: {(result, info)->Void in
thumbnail = result!
})
return thumbnail
}
