ionic4

[uniquejava]

优点:

真实设备上比如iphone调试太方便了 (safari)

坑点:: 使用form的地方, 要在xxx.module.ts中手动加入如下代码

@NgModule({
  imports: [CommonModule, FormsModule, ReactiveFormsModule, IonicModule, RouterModule.forChild(routes)],
  declarations: [Step2Page]
})
export class Step2PageModule {}

注意不是app.module.ts

每个用到module都要分别imports一次. 坑

[uniquejava]

setup

npm uninstall -g ionic
npm i -g ionic
ionic start hello blank --type=angular
cd hello
ionic serve

集成capacitor

ionic integrations enable capacitor
ionic build # and/or ionic build --production
ionic cap add ios
ionic cap sync
npx cap open ios

折行

在toast或actionsheet的header/title中使用换行符?

.toast-message {
  white-space: pre;
}

and \n for a line-break. 见: https://stackoverflow.com/questions/38597297/is-it-possible-to-have-newline-character-in-ionic2-toast

在capacitor项目中使用cordova pluglin

ionic cordova plugin add call-number

如下

npm i call-number
npm i @ionic-native/call-number

配色

src/theme/variables.scss

比如要把primary的颜色从默认的 #3880ff 改为 #38a1ea,一共要调整下面的4个值. 可以到这个页面计算出它的shade和tint颜色
