I have an app on the app store, that uses coredata as storage. I wan't to update the app with iCloud synchronization as new feature. Following apple`s sample code, I managed to have my core data storage synchronize between devices. However, I'm experiencing problems when either iCloud synchronization is turned off/on in the app on only one of the devices, or when the app is deleted from the device and the reinstalled. In both cases, data is not synchronized back to the device, although it is available just fine on a second device (which was not disabled/reinstalled). I also found that all

(0xE8008016). when trying to deploy my first app to an un-jailbroken device on iOS 4.2.6 (Verizon). The thing is, I do not have a Entitlements file in my project, as I am not distributing it at all, only putting it on one device. I have gone through all the hoops and loops apple puts you through (certificate, device, provisioning) down to the letter, and I cannot figure

How do I delete some data I put into the cloud? I made an app that when you enter a url in 1 view controller it uploads into the cloud, and when you go to another view controller it shows the url you entered before from the cloud in a webview. for example, when you enter www.hello.com, it goes into the cloud, and when you go to the webview on a different view controller it loads www.hello.com. My problem: When I enter a second url, it still loads the first one. How do I get it to load the latest one I uploaded? Is there a way to delete the first one when the second one is uploaded? You can

How to handle correct the following flow using Magical Record ? Assume that my app enable feature to switch iCloud sync on/off. The user installs the app. On startup he is asked about iCloud preference. His choice: do not use iCloud. The user creates some data in the app. Then he decides to store it in iCloud and enables iCloud. Later by some reason the user disables iCloud in the app. Data should be left locally. How to setup Magical Record correctly? UPDATE: Source code Implementing a switch to enable or disable iCloud in your app is also much easier in iOS 7, although it probably isn’t

I'm having nothing but trouble with NSUbiquitousKeyValueStore and getting it to reliably sync across two devices. It's starting to drive me mad. Mad. I watch my code make a call to: [[NSUbiquitousKeyValueStore defaultStore] setObject:_someData forKey:@"SomeData"]; [[NSUbiquitousKeyValueStore defaultStore] synchronize]; But more times than not, the data never shows up on the other device. I've seen it sync within a few seconds and other times I've waited for an hour and never seen a sync. I plug the devices into xcode and start debugging and sometimes the data suddenly pops up and other times

I'm using Core Data in an existing application. Now I want to integrate iCloud so that the user can synchronize their contents between their iOS-devices. To do that I've written the following code for my NSPersistentStoreCoordinator (of course the placeholders are filled out in my code): - (NSPersistentStoreCoordinator *)persistentStoreCoordinator { if (persistentStoreCoordinator_ != nil) { return persistentStoreCoordinator_; } NSURL *storeURL = [[self applicationDocumentsDirectory] URLByAppendingPathComponent:@"<DB_Name>.sqlite"]; persistentStoreCoordinator_ = [[NSPersistentStoreCoordinator

I've setup a custom zone subscription to receive (silent) push notifications from my custom record zone. Everything works fine on my iOS devices but I'm not able to receive the notifications on my Mac. To register the notifications I'm registering the notification type in applicationDidFinishLaunching : [[NSApplication sharedApplication] registerForRemoteNotificationTypes:NSRemoteNotificationTypeNone]; (Tried the other types with the same result) application:didRegisterForRemoteNotificationsWithDeviceToken: is then called with a valid token. Everything seems fine but when the custom zone
