Short example how I setup the synchronisation for iCloud sync with TICoreDataSync

gistfile1.m

- (void) registerSyncManager
{
    if (self.applicationSyncManager) return;
    

    TICDSLogVerbosity logVerbosity = [[NSUserDefaults standardUserDefaults] integerForKey:kIVTICDSLogVerbosity];
    [TICDSLog setVerbosity:logVerbosity];

    
    if (![self hasLocalDatabase]) {
        [self setDownloadStoreAfterRegistering:YES];
    }
    
    TICDSiCloudBasedApplicationSyncManager *manager = [TICDSiCloudBasedApplicationSyncManager defaultApplicationSyncManager];
    manager.shouldUseEncryption = NO;
    
    self.applicationSyncManager = manager;
    
    NSURL *iCloudLocation = self.cloudStoreURL;
    
    NSAssert(iCloudLocation != nil, @"Must be able to determine iCloud location to run this example");
    
#ifdef DEBUG
    NSLog(@"Using Sync Path: %@", iCloudLocation);
#endif
    
    if (!_ubiquityMonitor) {
        NSPredicate *newPredicate = [NSPredicate predicateWithFormat:@"(%K = FALSE OR %K = FALSE) AND NOT %K LIKE %@", NSMetadataUbiquitousItemIsDownloadedKey, NSMetadataUbiquitousItemIsUploadedKey, NSMetadataItemPathKey, @"*/ExternalResources/*"];

        _ubiquityMonitor = [[TIUbiquityMonitor alloc] initWithPredicate:newPredicate];
        _ubiquityMonitor.initiateTransfers = YES;
/*
        [_ubiquityMonitor startMonitoringWithProgressBlock:^(long long bytesToDownload, double percentageDownloading, long long bytesToUpload, double percentageUploading) {
            if (bytesToUpload > 0 || bytesToDownload > 0) {
                NSLog(@">>> ubiquity bytesToDownload: %lld bytesToUpload: %lld", bytesToDownload, bytesToUpload);
            }

        }];
*/
    }
    
    [manager setApplicationContainingDirectoryLocation:iCloudLocation];
    
    NSString *clientUuid = [[NSUserDefaults standardUserDefaults] stringForKey:kIVAppSyncClientUUID];
    
    if( !clientUuid ) {
        clientUuid = [TICDSUtilities uuidString];
        [[NSUserDefaults standardUserDefaults] setValue:clientUuid forKey:kIVAppSyncClientUUID];
    }
        
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(activityDidIncrease:) name:TICDSApplicationSyncManagerDidIncreaseActivityNotification object:manager];
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(activityDidDecrease:) name:TICDSApplicationSyncManagerDidDecreaseActivityNotification object:manager];
    
    [manager registerWithDelegate:self
              globalAppIdentifier:kIVGlobalAppIdentifier
           uniqueClientIdentifier:clientUuid
                      description:[self deviceDescription]
                         userInfo:[self ticdsUserInfo]];
}

Yes, exactly that. It's just SyncData in my case ;)

I can't remember exactly, but as far as I remember you need it to load all changed files directly on iOS as on iOS the iCloud data is lazyly loaded, AFAIK. It would be better to integrate that into the DocumentManager, though.

Okay, so you're using the TIUbiquityMonitor to monitor when data changes in iCloud. Are you doing anything else with it in your App Delegate or does something need to be implemented in startMonitoringWithProgressBlock to tell TICDS to sync?
