问题 There's nothing in the docs about this. I've just read a blog post on ionics website saying that it's possible to swipe to go back (like ios7) and I've seen the latest ng-conf where they talked about it as well, but nowhere to they mention on how to implement the damn thing. 回答1: No need to do a on-swipe-left.

问题 I am investigating using Ionic 4/ Capacitor to target Windows via the Electron option, for an application where I want to use SQLite. Using the Ionic Native SQLite plugin, which wraps this Cordova plugin, out of the box, as far as I can see, the Windows support is for UWP, and not Desktop, which runs using Electron in Ionic Capacitor wrapper.

问题 I am building a simple app with Ionic. But my app has a performance issue with initial loading time on cold start. Here is what I have done: collection-repeat instead of ng-repeat with 'track by' native scroll: overflow-scroll='true' use no cache with $ionicConfigProvider.views.maxCache(0); I cannot use crosswalk-webview because of one of the library I am using.
