iCloud file storage/exchange across devices - ios

Question

I am trying to store data to iCloud documents, and read it on another device logged in with the same account.
I can detect iCloud, send data to iCloud and read it back on the same device. I can detect the file is there from the second device, but I get an error 'NSCocoaDomainError - code 260' when I try to read or copy the file.
File Store code:
//CREATE FILE
NSError *error;
NSLog(#"string to write:%#",printString);
NSURL *ubiq = [[NSFileManager defaultManager] URLForUbiquityContainerIdentifier:nil];
if (ubiq == nil) {
return;
}
NSURL *cloudURL =[[ubiq URLByAppendingPathComponent:#"Documents" isDirectory:true] URLByAppendingPathComponent:#"CogwindInventory.txt"];
[printString writeToURL:cloudURL atomically:YES encoding:NSUTF8StringEncoding error:&error];
Code to run the query:
self.backups = [[NSMutableArray alloc] init];
self.query = [[NSMetadataQuery alloc] init];
[self.query setSearchScopes:[NSArray arrayWithObject:NSMetadataQueryUbiquitousDocumentsScope]];
NSPredicate *pred = [NSPredicate predicateWithFormat: #"%K like 'CogwindInventory.txt'", NSMetadataItemFSNameKey];
[self.query setPredicate:pred];
[[NSNotificationCenter defaultCenter] addObserver:self
selector:#selector(queryDidFinishGatheringRestore:)
name:NSMetadataQueryDidFinishGatheringNotification
object:self.query];
[self.CloudActivityIndicator startAnimating];
[self.query startQuery];
- (void)queryDidFinishGatheringRestore:(NSNotification *)notification {
NSMetadataQuery *query = [notification object];
[query disableUpdates];
[query stopQuery];
[self loadDataRestore:query];
[[NSNotificationCenter defaultCenter] removeObserver:self name:NSMetadataQueryDidFinishGatheringNotification object:query];
self.query = nil;
}
- (void)loadDataRestore:(NSMetadataQuery *)query {
[self.backups removeAllObjects];
for (NSMetadataItem *item in [query results]) {
NSURL *url = [item valueForAttribute:NSMetadataItemURLKey];
//[self.backups addObject:url.lastPathComponent];
[self.backups addObject: url.filePathURL];
}
if (self.backups.count > 0) {
[self retrievefile];
}
[self OperationComplete];
}
Code to do the read:
- (void) retrievefile
{
NSError *error = nil;
NSURL *ubiq = [self.manager URLForUbiquityContainerIdentifier:nil];
if (ubiq == nil) {
return;
}
NSURL *cloudURL =[self.backups objectAtIndex:0];
NSArray *localtoken = [[NSString stringWithContentsOfURL:cloudURL encoding:NSUTF8StringEncoding error:&error] componentsSeparatedByString:#"\n"];
if ((localtoken == nil) || (error !=nil)) {
[self.CloudStatusText setText: #"Restore operation failed."];
return;
} else {
[self.tokeninventory setPlayerInventoryNames:localtoken];
[self.CloudStatusText setText: #"Restore operation successful. New inventory available"];
}
}
The devices are OS 8.1.1 and OS 8.3. iCloud- Documents is enabled in Xcode, but not iCloudKit.
Any help appreciated. Thank you.
