nativescript

问题 My view is <Switch checked="{{ active }}" propertyChange="onCheckChange"/> exports.onCheckChange = function(args) { //Api Service call } Actually I am binding the active value by API call and the issue is that onCheckChange gets executed during the initial binding with false value, so whenever I initially set the active==true by api service call and load the page, the onCheckChange is executed with checked==false , can anyone give me an idea about this please. Note: Beginner in Nativescript

问题 I have angular 2 nativescript project and I use tns livesync android --watch or tns run android to see changes on both real device and emulator. It usually works fine but at some point it starts building and syncing old code and throws JS errors based on that code. It's usually solvable by reseting the whole project (remove platforms, node-modules, hooks) and tns install everything back. When I add new node modules and/or new custom components, I usually kill the lifesync and do the tns build

问题 I am trying to figure out a way to prevent users from zooming in and out on an iOS WebView (tns-ios 3.4.1) via pinch gestures & double tapping, essentially disabling all scaling like the html meta tag used to do before apple went to letting the user decide if he wants to zoom with iOS 10 and above. I found a solution for android here, for iOS it doesn't appear to be as trivial though. I am pretty new to the platform, is this currently possible at all? I found that NS recently switched from

问题 Im just now trying to get my hooks into nativescript with javascript and have a very basic question: let costFormatter= { toView(value){ console.log('Got:' + value); return '$' + value; }, toModel(value){ console.log('Got:' + value); return '$' + value; } }; http.getJSON("<My API Call>").then(function (r){ page.bindingContext = { deals: r, costFormatter:costFormatter }; }, function (e){ //// Argument (e) is Error! //console.log(e); }); In the above code, I define the cost formatter I just
