nativescript

问题 I am using Nativescript to create an Android and iOS App. As it is a kind of a calculator there are a lot of input fields for numbers. The numbers are decimal and can be negative.

问题 I need to rename my application and I'm not sure where to start. I tried manually changing the names of a few folders/files, but everything broke, I think because there were way more things using the original name than I had anticipated.

问题 I was wondering how to handle login/logout of the user so I did this: store.commit('load_state'); store.subscribe((mutations, state) => { ApplicationSettings.setString('store', JSON.stringify(state)); }); new Vue({ store, render: h => h('frame', [h(store.state.is_logged_in ?

问题 I am trying to get images into a grid on a Nativescript Angular App and then be able to tick them and move to the next page with the id's or names of those images. i can do the image grid but i can't make them tickable.
