How I can integrate iCloud to my AppDelegate? - ios

Question

I need help to integrate iCloud to my CoreData.
I have tried many changes on AppDelegate, but only Error:
"libc++abi.dylib: terminating with uncaught exception of type NSException"
I have a TeamID and a Developer Account.

Typical reasons for an error here include:
* The persistent store is not accessible;
* The schema for the persistent store is incompatible with current managed object model.
Check the error message to determine what the actual problem was.
If the persistent store is not accessible, there is typically something wrong with the file path. Often, a file URL is pointing into the application's resources directory instead of a writeable directory.
If you encounter schema incompatibility errors during development, you can reduce their frequency by:
* Simply deleting the existing store:
[[NSFileManager defaultManager] removeItemAtURL:storeURL error:nil]
* Performing automatic lightweight migration by passing the following dictionary as the options parameter:
[NSDictionary dictionaryWithObjectsAndKeys:[NSNumber numberWithBool:YES], NSMigratePersistentStoresAutomaticallyOption, [NSNumber numberWithBool:YES], NSInferMappingModelAutomaticallyOption, nil];
Lightweight migration will only work for a limited set of schema changes; consult "Core Data Model Versioning and Data Migration Programming Guide" for details.

i have a example that use the icloud but it is write for ios5, and i don't no what i have to change for ios7:
thats the Code for icloud Support in AppDelegate:
if((__persistentStoreCoordinator != nil)) {
return __persistentStoreCoordinator;
}
__persistentStoreCoordinator = [[NSPersistentStoreCoordinator alloc] initWithManagedObjectModel: [self managedObjectModel]];
NSPersistentStoreCoordinator *psc = __persistentStoreCoordinator;
// Set up iCloud in another thread:
dispatch_async(dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_DEFAULT, 0), ^{
// ** Note: if you adapt this code for your own use, you MUST change this variable:
NSString *iCloudEnabledAppID = #"5KFJ75859U.Tim-Roadley.Staff-Manager";
// ** Note: if you adapt this code for your own use, you should change this variable:
NSString *dataFileName = #"StaffManager.sqlite";
// ** Note: For basic usage you shouldn't need to change anything else
NSString *iCloudDataDirectoryName = #"Data.nosync";
NSString *iCloudLogsDirectoryName = #"Logs";
NSFileManager *fileManager = [NSFileManager defaultManager];
NSURL *localStore = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:dataFileName];
NSURL *iCloud = [fileManager URLForUbiquityContainerIdentifier:nil];
if (iCloud) {
NSLog(#"iCloud is working");
NSURL *iCloudLogsPath = [NSURL fileURLWithPath:[[iCloud path] stringByAppendingPathComponent:iCloudLogsDirectoryName]];
NSLog(#"iCloudEnabledAppID = %#",iCloudEnabledAppID);

withIntermediateDirectories:YES
attributes:nil
error:&fileSystemError];
if(fileSystemError != nil) {
NSLog(#"Error creating database directory %#", fileSystemError);
}
}
NSString *iCloudData = [[[iCloud path]
stringByAppendingPathComponent:iCloudDataDirectoryName]
stringByAppendingPathComponent:dataFileName];
NSLog(#"iCloudData = %#", iCloudData);
NSMutableDictionary *options = [NSMutableDictionary dictionary];
[options setObject:[NSNumber numberWithBool:YES] forKey:NSMigratePersistentStoresAutomaticallyOption];
[options setObject:[NSNumber numberWithBool:YES] forKey:NSInferMappingModelAutomaticallyOption];
[options setObject:iCloudEnabledAppID forKey:NSPersistentStoreUbiquitousContentNameKey];

else {

[psc unlock];
}
dispatch_async(dispatch_get_main_queue(), ^{
[[NSNotificationCenter defaultCenter] postNotificationName:#"SomethingChanged" object:self userInfo:nil];
});
});
return __persistentStoreCoordinator;
i have also this code for ManagedObjectContext :
- (NSManagedObjectContext *)managedObjectContext {
if (__managedObjectContext != nil) {
return __managedObjectContext;
}
NSPersistentStoreCoordinator *coordinator = [self persistentStoreCoordinator];
if (coordinator != nil) {
NSManagedObjectContext* moc = [[NSManagedObjectContext alloc] initWithConcurrencyType:NSMainQueueConcurrencyType];
[moc performBlockAndWait:^{
[moc setPersistentStoreCoordinator: coordinator];
[[NSNotificationCenter defaultCenter]addObserver:self selector:#selector(mergeChangesFrom_iCloud:) name:NSPersistentStoreDidImportUbiquitousContentChangesNotification object:coordinator];
}];
__managedObjectContext = moc;
}
return __managedObjectContext;
}
- (void)mergeChangesFrom_iCloud:(NSNotification *)notification {
NSLog(#"Merging in changes from iCloud...");
NSManagedObjectContext* moc = [self managedObjectContext];
[moc performBlock:^{
[moc mergeChangesFromContextDidSaveNotification:notification];
NSNotification* refreshNotification = [NSNotification notificationWithName:#"SomethingChanged"
object:self
userInfo:[notification userInfo]];
[[NSNotificationCenter defaultCenter] postNotification:refreshNotification];
}];
}
