nativescript

问题 My Nativescript iOS app saves some user created data using the nativescript-localstorage plugin. I want to be sure that users have a place to back-up this data. The most straightforward option seems to be that they can include the app's data in an icloud backup (ie, icloud -> icloud Drive -> then allow the app to be backed up in the drive ). When I have used " $ tns run ios " and run the app locally on my phone, the app properly runs on my phone, but it does not appear as an option for

问题 I am new to Native Script. How can I display an image from local storage? I used the nativescript-imagepicker but then, I don't know where the image is stored. I am using this code. var imagepicker = require("nativescript-imagepicker"); var context = imagepicker.create({ mode: "single" }); // use "multiple" for multiple selection let SlcImg = ""; exports.imgPic = function() { context .authorize() .then(function() { return context.present(); }) .then(function(selection) { selection.forEach

问题 In my nativescript iOS app, users will create a file, and then share the file via text message with other users. I'm using angular. I expect that I can use the file system to create and save the file, and then use nativescript-share-file to open up the text message and attach the file. BUT: how do I enable the recipient to tap on the file in the text message, and have that tap automatically open the app with the file there? It's that piece I am not sure of: user taps on the file in the text

问题 So I've been learning Javascript, TypeScript, Angular, and NativeScript for several months now and I just took on an app development project for a client. I know that there are emulators that you can use to see how what you've developed might look on an iOS and Android device. I also know about the NativeScript Preview app that you can download from app stores. The problem with the Preview app is that it doesn't appear to be compatible with certain Angular plugins like Firebase...unless I'm

问题 I have a script that should try to connect 3 times to server if this fails navigate the user to the No Connection page . I don't know how to attempt a connection 3 times and then navigate user to the No Connection page if this fails. How can I use my code to achieve this problem. Here is the code I have so far: const fetchModule = require('fetch'); const frameModule = require('ui/frame'); let timeTrig; const waitPeriod = 7000; function checkServerStatus() { if (timeTrig) { clearTimeout

问题 In react native we have: type MkdirOptions = { NSURLIsExcludedFromBackupKey?: boolean; // iOS only }; What is the equivalent in NativeScript? I need a directory under knownFolders.documents() that will not be backed-up to iCloud. 回答1: Try this, NSURL.URLWithString(path).setResourceValueForKeyError(true, NSURLIsExcludedFromBackupKey); Where path is complete path of your file or folder. 来源： https://stackoverflow.com/questions/58363089/using-nsurlisexcludedfrombackupkey-in-nativescript

问题 I am developing android/ios app using Nativesript + angular. I want to display a ListView in my app. For that ListView , I want to use firestore database product by Firebase as Backend data provider. What I want: 1. I don't want users to login or to be authenticated to use the app. 2. I want the data coming from firebase database can only be used by my app. If some other apps or anonymous utilizes the data, is there any way I can block them? I have tried putting rules like service cloud

问题 After updating from NS 5 to NS 6, I got the following error when trying to run my application on Android: [Vue warn]: Error in v-on handler: "TypeError: Cannot read property 'ViewCompat' of undefined" 回答1: This turned out to be a problem in a plugin I was using that needed to be updated to use the AndroidX support library. I found it by searching my plugins for the string 'ViewCompat' - you should see a reference to AndroidX rather than android.support. Specifically, I resolved my issue by

问题 Edit: I have asked a related question about what the current state of RadList View is (does it exist anymore?) here. Original question: Is *ngFor ok to use for lists in Nativescript? Normally, I find people recommending RadListView, but for ease of use and being able to customize the list, I strongly prefer *ngFor. However, I recently had a few glitches using *ngFor, so I want to be sure it is stable in the most recent Nativescript. Details: In my iOS app, built with Nativescript, I have a
