ionic2

问题 I'm looking for ionic2 best practice to show loadings, alerts and console logs.. so instead of repeat the code below in each page so I can call it once. For example code to show loading: showLoading() { this.loading = this.loadingCtrl.create({ content: '' }); this.loading.present(); } Is it the best practice to create a provider, and show the loading from the last? or the provider doesn't support loading or something similar ? Thanks. 回答1: I usually create a lib folder (or module if you want)
