I'm trying to download an image called "aaa.jpeg" in my s3 bucket using AWSMobileHubHelper. I found this function on their documentation site.
func downloadContent(content: AWSContent, pinOnCompletion: Bool) {
content.downloadWithDownloadType( .Always, pinOnCompletion: pinOnCompletion, progressBlock: {(content: AWSContent?, progress: NSProgress?) -> Void in
// Handle progress feedback
}, completionHandler: {(content: AWSContent?, data: NSData?, error: NSError?) -> Void in
if let error = error {
print("Failed to download a content from a server.)")
// Handle error here
return
}
// Handle successful download here
if let image = UIImage(data: data!){
self.imageView = image
}
})
}
Once the download is successful (it Did, There is no error message), I'm trying to assign the image to an imageView. I can tell that the data has been downloaded successfully. I can print the data and see a familiar binary structure of an image. But for some reasons I can't assign the UIImage to the imageView. Because I can't convert the data to a UIImage.
I just want to know if this is the proper way to download image from s3 or am I missing something. Does "data" in the completion block carry the downloaded image? I can't seem to find any documentations on this.
Is this the correct function to use to download from S3?
