AWS S3 SDKv2 and image upload ios on turk

Question

I uploaded image to AWS S3 with with code :

    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *filePath = [[paths objectAtIndex:0] stringByAppendingPathComponent:pathComp];
    [UIImageJPEGRepresentation(myImage,0.9) writeToFile:filePath atomically:NO];
    filePath = [NSString stringWithFormat:@"file:///private%@", filePath];
    NSURL* fileUrl = [NSURL URLWithString:filePath];
    AWSS3TransferManagerUploadRequest *uploadRequest = [AWSS3TransferManagerUploadRequest new];
    uploadRequest.key = key;
    uploadRequest.body = fileUrl;
    uploadRequest.contentType = @"image/jpeg";

It's uploaded normally, but in mechanical turk i can't open preview

This page contains the following errors:

error on line 1 at column 1: Document is empty
error on line 1 at column 1: Encoding error
Below is a rendering of the page up to the first error. 

Answer 1

When creating a file URL using NSURL , you should use + fileURLWithPath: . You should change this line

NSURL* fileUrl = [NSURL URLWithString:filePath];

to

NSURL* fileUrl = [NSURL fileURLWithPath:filePath];

You should double check if the file was successfully uploaded using the AWS Management Console .

Also, by default, all Amazon S3 resources - buckets, objects, and related subresources - are private: only the resource owner, an AWS account that created it, can access the resource. You can modify ACL to change the permission.
