transfer image from DKasset to custom class

[zhangao0086]

Use fetchFullScreenImageWithCompleteBlock... like this:

assets.first?.fetchFullScreenImageWithCompleteBlock({ image, info in
    let object = CustomObject()
    object.image = image
})

and how to make all photos in DKAsset to new class?

[zhangao0086]

Maybe I should provide a sync method to fetch an image..

[aldolazuardi]

yeah that would be great, anyway im using this code

    for asset in photos{
        asset.fetchFullScreenImageWithCompleteBlock({ image, info in
           let images = image
            let data1 = dataImage(userId: "1", value: 1.0, photo: images)
            self.datas += [data1]
            print("*")
        })
    }
    print("datas: \(datas.count)")

i have 6 'image' in photos(DKAsset) and '*' print 6 times, but datas.count is 0, do you have any guess what did i missed?

Try this:

let options = PHImageRequestOptions()
options.deliveryMode = .HighQualityFormat
options.resizeMode = .Exact;
options.synchronous = true

for asset in photos {
    asset.fetchImageWithSize(UIScreen.mainScreen().bounds.size.toPixel(), options: options,
        completeBlock: { image, info in
            let images = image
            let data1 = dataImage(userId: "1", value: 1.0, photo: images)
            self.datas += [data1]
            print("*")
    })
}
print("datas: \(datas.count)")

I just found the answer of this problem, turns out it prints 0 because loop finishes very quickly, while all 6 asset fetches occur in the background. http://stackoverflow.com/questions/34890905/failed-to-input-data-to-class-model-swift/34891231#34891231.

Anyway thank you for the great lib and fast answers bro!

Yes, the fetches method executed in the background. So you can specific the synchronous of the PHImageRequestOptions to true like my above answer :)
And I've added two functions to sync fetch images in 3.0.6:

/**
Fetch an image with the current screen size.

- parameter sync:          If true, the method blocks the calling thread until image is ready or an error occurs.
- parameter completeBlock: The block is executed when the image download is complete.
*/
public func fetchFullScreenImage(sync: Bool, completeBlock: (image: UIImage?, info: [NSObject : AnyObject]?) -> Void)

/**
Fetch an image with the original size.

- parameter sync:          If true, the method blocks the calling thread until image is ready or an error occurs.
- parameter completeBlock: The block is executed when the image download is complete.
*/
public func fetchOriginalImage(sync: Bool, completeBlock: (image: UIImage?, info: [NSObject : AnyObject]?) -> Void)

Anyway please let me know if you have any questions :)
