Mark,
Can you please check if the file upload was successful and that the file exists there (and its name) - you can do this from Kinvey Console->Data and then select “Files” in the dropdown.
__NOTE for downloadFileByName:
__ If there is no matching file by the specified name, the result will be an empty `downloadedResources` array, and NOT a 404 error. This is a change of behavior from previous versions.
Thanks,

I've started using Kinvey, iOS to be specific, before few days. However, I'm not successfull in fetching the images being uploaded. I'm uploading an image and saving it's ID and URL in Post object.
Below is the code for uploading image:
NSData* data = UIImageJPEGRepresentation([imageViewPost image], 0.9); //convert to a 90% quality jpeg
KCSMetadata *metadata = [KCSMetadata new];
[metadata setGloballyReadable:YES];
[KCSFileStore uploadData:data options:@{KCSFilePublic:@(YES),KCSFileACL:metadata,KCSFileMimeType:@"image/jpeg"} completionBlock:^(KCSFile *uploadInfo, NSError *error) {
NSLog(@"Upload finished. File id='%@', error='%@'.", [uploadInfo fileId], error);
if(!error && uploadInfo){
Post *newPost = [Post new];
newPost.postTitle = textFieldTitlew.text;
newPost.postOwnerID = CURRENT_USER.userId;
newPost.postOwnerName = CURRENT_USER.username;
newPost.postDescription = textFieldDescription.text;
newPost.postLink = textFieldLink.text;
newPost.mediaURL = uploadInfo.remoteURL.absoluteString;
newPost.postMediaID = [uploadInfo fileId];
[KINVEY_MANAGER.postsStore saveObject:newPost withCompletionBlock:^(NSArray *objectsOrNil, NSError *errorOrNil) {
[appDelegate stopLoadingView];
if (errorOrNil != nil) {
//save failed
NSLog(@"Save failed, with error: %@", [errorOrNil localizedFailureReason]);
[appDelegate showAlertWithMessage:[errorOrNil localizedDescription]];
} else {
//save was successful
NSLog(@"Successfully saved event (id='%@').", [objectsOrNil[0] kinveyObjectId]);
[appDelegate showAlertWithMessage:@"Post added successfully."];
}
} withProgressBlock:^(NSArray *objects, double percentComplete) {
}];
}else{
[appDelegate stopLoadingView];
}
} progressBlock:nil];
I'm unable to load the image using the post.mediaURL property. I want to load the image using AFNetworking, that's why I'm saving the URL. I tried below code as well:
[KCSFileStore downloadFileByName:post.postMediaID completionBlock:^(NSArray *downloadedResources, NSError *error) {
if(!error && downloadedResources.count>0){
KCSFile* file = downloadedResources[0];
NSURL* fileURL = file.localURL;
UIImage* image = [UIImage imageWithContentsOfFile:[fileURL path]]; //note this blocks for awhile
imageViewPostImage.image = image;
}
} progressBlock:^(NSArray *objects, double percentComplete) {
}];
But always get downloadedResources as "0 objects" and no error at all.
Please help me fix this. Thanks in advance.
