问题 I have an app where the PersistentStoreCoordinator is set up within AppDelegate. I want to load a new sqlite database from a list of saved sqlite files. I'm happy with deleting the existing Persistent Store and sqlite file and replacing the sqlite file with the one loaded from the table. However, how do I reload/refresh the PersistentStoreCoordinator from the ViewController action of selecting the new file? I've tried setting AppDelegate as a delegate of the ViewController, but this seems to

问题 I implemented a local notification in my game app that fires up once a day for a daily bonus.

问题 I want to provide a log on view controller so my users can authenticate prior to being presented the tab bar controller. In the code displayed below, I get the error "Could not cast value of type 'LogInViewController' to 'UITabBarController'.

问题 I have an iOS application which uses local notifications. When the app is running in the background or is active, I use the application didReceiveLocalNotification methods and that works great. But when the app is closed (not running in the background), I use the application didFinishLaunchingWithOptions method to control what happens when the notification is handled. However, the problem I have is that the notification is always (null) in the didFinishLaunchingWithOptions method. Here is my
