Download images through CloudFront (Amazon)

Question

I have an app that needs to download some images from S3. I tried to setup a new CloudFront distribution, pointed the origin to my S3 bucket and wondering how will this change the way I access my images in my app. My app just request the images to S3 like that:

    S3GetObjectRequest *getObjectRequest = [[S3GetObjectRequest alloc] initWithKey:path withBucket:PICTURE_BUCKET];

    S3GetObjectResponse *getObjectResponse = [self.s3 getObject:getObjectRequest];

    UIImage *img = [[UIImage alloc]initWithData:getObjectResponse.body];

Here, PICTURE_BUCKET is the name of my S3 bucket and path is the name of the image (64758_244.jpg).

How could I access this image through CloudFront?

I've found that

iOS AWS SDK and CloudFront - accessing images

but I am new with Amazon Mobile Services development and I don't know how to do it.

Thanks.

I would recommend using AFNetworking for asynchronous image downloading — David Ben Ari, Mar 17 '13 at 16:15

If your question is simply how to find the URL to access Cloudfront images, this is one method.

From cloudfront, check the distribution settings (under the i icon) and note the domain name: I have one at: d3foqimq5fy14v.cloudfront.net and this is for my S3 bucket titled panchroma2013
In S3, open the properties pane for an image and copy the link URL I have one at: https://s3.amazonaws.com/panchroma2013/template/panchroma-website-design.png
While there, double check file permissions. You may have to add Grantee: Everyone, yes to Open/Download
The cloudfront url for this image is my cloudfront domain name + S3 url after the bucket name, ie:

http://d3foqimq5fy14v.cloudfront.net/template/panchroma-website-design.png

Hope this does the trick for you!

Hi David, thanks for your response. I have it really clear now. The only thing I don't have clear is now how to access to this image. I just have to create a NSData initialized with contentsOfURL where the URL is that cloudfront url? – VICTORGS3 Mar 18 '13 at 22:52

Hi Victor, apps aren't my dept. unfortunately. As a stab in the dark though, is there anything on this page that helps you? http://www.raywenderlich.com/5492/working-with-json-in-ios-5 – David Taiaroa Mar 19 '13 at 00:11
