问题 I've seen that this question has been asked a few times, but no one seems to have an answer. I am trying to create an autocorrect feature on a custom keyboard, but I am completely lost as to how to do so. Apple gives some documentation, but it's not very detailed. I know it has something to do with UILexicon data, but I'm not sure what to do with it and how to use it to correct strings of text the user is typing. Any help would be greatly appreciated. What I have found so far: let controller

问题 I have followed this recipe in order to use a Swift class in an existing Objective-C project MyProject . That works fine. However, I'm still not able to use the same Swift class in the same project's unit tests. The compiler marks the line where my Objective-C unit test says #import "MyProjectTests-Swift.h" with file not found . If tried changing the test target's Product Module Name from its default MyProjectTests to MyProject as suggested in a comment to this (unanswered) question. However

问题 How can I implement it in the new language of Apple: Objective-C code: - (void)touchesBegan:(NSSet *)touches withEvent:(UIEvent *)event { for (UIView *view in self.view.subviews) [view resignFirstResponder]; } I have tried to do so. But the keyboard does not disappear: Swift code: override func touchesBegan(touches: NSSet, withEvent event: UIEvent) { super.touchesBegan(touches, withEvent: event) self.view.resignFirstResponder() } 回答1: You could probably go with: self.view.endEditing(true) 回答2

问题 I'm having some trouble with running a webapp in a WKWebView (specifically: some buttons are not responding). I used this tutorial as a guide and did succeed in having the webview display my webapp. So now I want to debug the javascript code. I know the webapp works, since I've tried it in both an android webview as well as countless browsers (including safari on the iPad simulator I'm using). After some quick googling, I found out how to debug javascript inside a UIWebView using Safari.

问题 I'd want to move the Legal label to the right side. On iOS 6 and 7 the below solution was working fine, however on iOS 8.3 it seems to not work. I get the label, then with a timer (0.1 sec) in viewDidLayoutSubviews I call this method : -(void)moveLegalLabel { UIView * legalLink = [self attributionView]; legalLink.frame = CGRectMake(self.mapView.frame.size.width - legalLink.frame.size.width - 10, self.mapView.frame.size.height - legalLink.frame.size.height - 10 , legalLink.frame.size.width,

问题 Question: Are there ways to animate anything within the LaunchScreen.xib file of an Xcode 6 Project targeted to deploy for iOS 8.1+ ? Context: I'm looking to make simple animations to convey activity or serve as a distraction to the user while they wait... Examples: A Loading Bar Activity Indicator Animated GIF Move a UIImage across the Screen Rotate an Image 回答1: Nope. The Launch Image is shown only during the time period between when the user chooses to launch your app and when your app has

问题 I am listneing to actions pressed for my local notifications, but is there a way to determine when the user dismisses a notification? Here is how I'm listening to my actions in my AppDelegate, but the dismiss doesn't fire this: func application(application: UIApplication, handleActionWithIdentifier identifier: String?, forLocalNotification notification: UILocalNotification, completionHandler: () -> Void) { var actionName: String? = nil if let identifier = identifier { switch identifier { case

问题 I am trying to open a PDF file that I have stored locally within my app in iBooks. The app currently has a list of "literature" in a table view and when each cell is tapped the app segues to a webView that displays the PDF file (works great). I have made a BarButton at the top right in navBar to allow the user to open the PDF in iBooks (so they can store it on his/her device). So far the button will open a UIDocumentInteractionController that displays all apps on the device that can open the

问题 Hi my problem is regarding the rotation of two sprites. When I touch the right half of the screen the rotation starts and moving sprite2 and sprite3. If I touch the left half of the screen the rotation stops because velocity-velocity = 0. If I touch the left half again the rotation begins. However, if I touch the half of the screen corresponding with the current rotational-direction the velocity is duplicated. I want to be able to change the direction of the rotation, but for the speed to
