S3 upload file missing data on device, but not on simulator about asi-http-request HOT 5 CLOSED

Update. The issue seems to only be with PNG files. I think it might be similar to the same problem that occurs on the cocoahttpserver here:

http://code.google.com/p/cocoahttpserver/issues/detail?id=15#c4

I'm not sure what the deal is with png files on the iPhone.

I think I could fix the issue the same way the cocoahttpserver fixes the issue if I stream a file from memory as opposed to from the disk. I'm not sure how to do that right now. If anyone does, please post.

Are you trying to upload a png you added to your project?

If I'm reading it correctly, the problem on the link you sent seems to be related to Xcode pre-multiplying the alpha on the image, which makes the png unreadable by other apps.

To use the fix they suggest, try something like this:

UIImage *imagePNG= [UIImage imageWithContentsOfFile:filePath];
NSData *pngData= UIImagePNGRepresentation(imagePNG);
[pngData writeToFile:somewhere atomically:NO];
ASIS3Request *request = [ASIS3Request PUTRequestForFile:somewhere withBucket:bucket path:path];

Writing it back to a file is necessary because ASIS3Request doesn't have support for uploading data except from a file, though I think this would be a worthwhile addition to the class.

Thanks

Thanks for the reply. I'm trying to upload a png that I added to the project bundle. I tried to read the file straight from disk. I will try what you're suggesting. I am pretty sure there is some sort of issue with the alpha on the image because when I view image info of the uploaded file, it's different from the alpha value of the original image.

Uploading from data would rock!

Added PUTRequestForData:etc to ASIS3Request

Also fixed unit tests for S3 on Mac, continued fallout from that setDoubleValue: debacle
