问题 Is it possible to save and load data on Today Extension using NSUserDefaults? After closing the Notification Center, the widget behaves like an app which is terminated, so any data results lost. How could I solve this issue? This is my code: NSUserDefaults *defaults; - (void)viewDidLoad { [super viewDidLoad]; defaults = [NSUserDefaults standardUserDefaults]; NSArray *loadStrings = [defaults stringArrayForKey:@"savedStrings"]; if ([loadStrings objectAtIndex:0] != nil) { [display setText:

问题 I'm not sure if I am the only one experiencing this program, but I have tried searching and have not been able to find anyone in my current situation. I downloaded Xcode 6 beta and was interested in Extension programming for iOS 8. However, I have been unable to locate the extensions in my project templates when creating a new project in Xcode, I saw a YouTube video (unrelated to extension programming) but I did notice that the option was not there for the said video. Now, I have had a look

问题 I'm developing app and share extension and trying to use core data. But when I'm inserting items in the extension those items only visible in extension but not from container app (e.g I perform NSFetchRequest from app and getting zero items but in app I got >0). I'm using the following code for getting the persistent container: lazy var persistentContainer: NSPersistentContainer = { let container = NSPersistentContainer(name: "appname") container.loadPersistentStores(completionHandler: {

问题 When I make any iOS 8 Today Extension, there is an empty space on the left of approximately 48px, even if in Interface Builder I place a label on the left side at x=0. I have seen that some apps, however, use a full-width widget. How can I achieve something similar? Thanks! UPDATE: SOLVED I put here the sample code because I guess it will be useful to someone. As suggested by @matteo-lallone, the correct way to do this is: -(UIEdgeInsets)widgetMarginInsetsForProposedMarginInsets:(UIEdgeInsets

问题 What is the best way to detect a device's orientation in an application extension? I have had mixed results with solutions I've found on here: How to detect Orientation Change in Custom Keyboard Extension in iOS 8? Get device current orientation (App Extension) I have looked at size classes and UITraitCollection and found that the device inaccurately reports that it is in portrait when it is in fact in landscape (not sure if this is OS bug, or I am not querying the right APIs the right way).

问题 I want to launch my containing app. I tried using URL schemes. The URL scheme launched the app from other places - so the problem is not there. Looks like this object is nil: self.extensionContext thus i can't run this method: [self.extensionContext openURL:url completionHandler:nil]; Can I launch my app? Do URL Schemes work in a custom keyboard? thanks! 回答1: Try this code UIResponder* responder = self; while ((responder = [responder nextResponder]) != nil) { NSLog(@"responder = %@",

问题 I've implemented a Today widget for my application +Quotes which displays the day's quote within the notification center with the help of these Apple Docs. What I'd like to accomplish is opening the Containing App, in this case +Quotes, when the user taps the +Quotes widget within their Today notification view, not entirely sure what to call this, as Calendar would if you tapped it in the Today view. I've tried overlaying a button over the label which would call -(void)openURL:(NSURL *)URL

问题 Can a custom keyboard communicate with the companion app at runtime? Can a custom keyboard dynamically display content based on states set in the companion app? If so, what API’s/documentation is available for this communication between the extension and app? 回答1: Here is a nice paragraph from the documentation that could get you started in sharing data with your companion app: https://developer.apple.com/library/prerelease/ios/documentation/General/Conceptual/ExtensibilityPG

问题 I have the same issue in this post, i follow all recommended in that answers but notting works, in my case the difference is that i have a table view controller. I have tried in many ways to prevent this from happening. example: -(void)viewDidLayoutSubviews { //the next 2 lines was tested with self.tableView and self.view [self.view.topAnchor constraintEqualToAnchor:self.topLayoutGuide.bottomAnchor constant:8.0].active = YES; [self.view constraintEqualToAnchor:[self.topLayoutGuide
