Uploading multiple files to a single row parse.com - objective-c

Question

So I'm using the following code to upload multiple files to a single row of a class.
for (NSString* currentString in directoryContents){
NSLog(#"%#",currentString);
NSString *temp2 = [temp stringByAppendingPathComponent:currentString];
PFFile *file = [PFFile fileWithName:currentString contentsAtPath:temp2];
[file saveInBackground];
PFObject *obj = [PFObject objectWithClassName:#"DreamBits"];
if ([currentString isEqualToString:#"index.html"]) {
[obj setObject:file forKey:#"index"];
}
else {
count += 1;
NSString *filen = [NSString stringWithFormat:#"file%i",count];
NSLog(#"%#",filen);
[obj setObject:file forKey:filen];
}
[obj saveInBackground];
}
The issue is I'm getting the files in different rows for some reason. Any idea how I can correct this?

I am modified your code little bit. I am not run this code but hope it helps you.
PFObject *obj = [PFObject objectWithClassName:#"DreamBits"];
for (NSString* currentString in directoryContents){
NSLog(#"%#",currentString);
NSString *temp2 = [temp stringByAppendingPathComponent:currentString];
PFFile *file = [PFFile fileWithName:currentString contentsAtPath:temp2];
if ([currentString isEqualToString:#"index.html"]) {
[obj setObject:file forKey:#"index"];
}
else {
count += 1;
NSString *filen = [NSString stringWithFormat:#"file%i",count];
NSLog(#"%#",filen);
[obj setObject:file forKey:filen];
}
}
[obj saveInBackground];
Create the PFObject outside the loop.Set all the PFFile object to the PFObject inside the loop.
After loop, save the PFObject. It is better to use the method :
[obj saveInBackgroundWithBlock:^(BOOL succeeded, NSError *error)
{
//Check whether the upload is succeeded or not
}];

I have used this method for upload profile and thumb image in a row in the Parse Server table. Using swift 4 and Parse SDK 1.17.1. Hope this technic will help.
func uploadImage(profileImage: UIImage, profileImageName: String, thumbImage: UIImage, thumbImageName: String) {
if let profileImagefile = PFFile.init(name: profileImageName, data: profileImage.jpegData(compressionQuality: 1)!) {
let fileObject = PFObject(className:"ProfileImage")
fileObject.setValue(profileImagefile, forKey: "profile_image")
fileObject.saveInBackground { (success, error) in
if error == nil {
print("thumb image path: \(profileImagefile.url ?? "")")
if let thumbImage = PFFile.init(name: thumbImageName, data: thumbImage.jpegData(compressionQuality: 0.5)!) {
fileObject.setValue(thumbImage, forKey: "thumb_image")
fileObject.saveInBackground(block: { (result, fileError) in
if fileError == nil {
print("thumb image path: \(thumbImage.url ?? "")")
}else {
print("error on thumb upload: \(result)")
}
})
}
}else {
print("error on file upload: \(error.debugDescription)")
}
}
}
}
