问题 I'm trying to build an today extension for my app. I'm using CoreData and NSFetchedResultsController and get the following error: Use of undeclared type 'AppDelegate' In this line of code: var appDel: AppDelegate = UIApplication.sharedApplication().delegate as AppDelegate. Does someone know how to solve this error / use AppDelegate in the today extension and would like to help me? 回答1: A Today Extension isn't an application, so UIApplication and AppDelegate aren't available. I'm not for sure

问题 Apple documentation suggests setting the height of Today Extensions using autolayout. If a widget has additional content to display, you can rely on Auto Layout constraints to adjust the widget’s height as appropriate. If you don’t use Auto Layout, you can use the UIViewController property preferredContentSize to specify the widget’s new height. However, every example and tutorial I have seen ends up using preferredContentSize . All of my attempts to set the height via autolayout lead to

问题 I am developing an iPhone app with a Today Extension . The app has a Model module that loads from/saves to NSUserDefaults . Since I want this information to be available to both the main app and the extension, I use an app group: let storage = NSUserDefaults(suiteName: "group.etc.etc.etc...") Both the app and the extension can access the information without any problem. The main app occasionally might create a local notification to present to the user. That notification has two actions

问题 I have an application and a today extension that are sharing a Core Data persistent store using a security group identifier. The main app updates the Core Data store and the extension only reads from the store. I am using a NSFetchedResultsController in both the app and the extension to retrieve the objects. This basically works, except that when the main app adds new objects to the store they aren't visible to the extension immediately. Similarly the extension can still see objects after

问题 An app I am working on needs a Today Extension / Widget. Are there any resources on how to build one into an Cordova app? I found this, but it's not written very clearly and from what I understood seems to be a native app that only uses a HTML5 element in the app and widget to display some data :/ 回答1: Yes you are right, today extension are a native thing. I recently also did a lot of research on how to integrate one into a cordova project dynamically and ended up creating my own cordova

问题 I am finding that my Notification Center widget does not reload very often. Because of this, out of date data being presented. I have not been able to find a way to get the widget to refresh every time I open the Today view. I have seen apps such as NBA Gametime that are able to update every time I pull down to see the widget. How can I get this functionality in my app? 回答1: Based on my own experimentation and also reports in this SO thread, it appears that the TodayViewController.viewDidLoad

问题 I am trying to fetch a list of PFObjects of a PFUser to display in the iOS 8 Today Widget. Following this blog post by Parse, I've enabled the same App Groups and Keychain Sharing in both my main app and extension in Xcode. I've also enabled the following in the AppDelegate of my main app and the viewDidLoad of my Today Extension: [Parse enableLocalDatastore]; [Parse enableDataSharingWithApplicationGroupIdentifier:@"group.com.me.myapp" containingApplication:@"com.me.myapp"]; [Parse

问题 I was wondering is it possible to update the text label of a timer in a today widget. I took a look around but nothing helped me. 回答1: Yes you can. I have just tested and it works. You just have to add your timer to the main run loop NSRunLoopCommonModes: RunLoop.main.add(yourTimerName, forMode: .commonModes) import NotificationCenter class TodayViewController: UIViewController, NCWidgetProviding { @IBOutlet weak var strTimer: UILabel! var timer = Timer() func updateInfo() { strTimer.text =

问题 I have some custom buttons in my host app that I'd like to use in the Today Extension. They work just fine in the app but do not display in the widget. The button on the left is my custom button class, the one on the right is a UIButton. If I change it to my custom class it too disappears. Any thoughts why this might be happening? ----------------------EDIT------------------------ Well, somehow I managed to get it to display but sometimes it's not drawing the whole button and sometimes it's
