How to set desktop icons and startup page in uniapp

With the continuous development of mobile application technology, the appearance and user experience of applications have also become important factors that developers need to consider. When developing mobile applications, desktop icons and startup pages are indispensable elements, which can add beauty to the application and improve user experience. In uniapp, setting desktop icons and startup pages is also very simple.

1. Set desktop icon

In uniapp, you can set the desktop icon by setting the icon path in the manifest.json file. In the manifest.json file, find the "icons" node and add desktop icon paths of different sizes under this node. For example:

{
  "name": "uni-app",
  "icons": [
    {
      "src": "/static/favicon-16x16.png",
      "sizes": "16x16",
      "type": "image/png"
    },
    {
      "src": "/static/favicon-32x32.png",
      "sizes": "32x32",
      "type": "image/png"
    },
    {
      "src": "/static/favicon.ico",
      "sizes": "64x64 32x32 24x24 16x16",
      "type": "image/x-icon"
    }
  ]
}

In the above code, three icon paths of different sizes are set. It should be noted that the set icon must exist in the static directory.

2. Set the startup page

In uniapp, setting the startup page requires the use of the plug-in uni-app-plus-splashscreen. This plug-in provides rich startup page setting functions. Through this plug-in, you can set the background color, pictures, animation effects, etc. of the startup page.

First, you need to install the uni-app-plus-splashscreen plug-in into the project. You can install it through npm. The command is as follows:

npm install uni-app-plus-splashscreen

After the installation is complete, introduce the plug-in in main.js ：

import Vue from 'vue'
import App from './App'
import uniSplashScreen from 'uni-app-plus-splashscreen'

Vue.config.productionTip = false

App.mpType = 'app'

Vue.prototype.$uniSplashScreen = uniSplashScreen

const app = new Vue({
  ...App
})
app.$mount()

Next, set the startup page in App.vue.

<template>
  <div>
    <view>
      <!--在这里放启动页内容-->

    </view>
  </div>
</template>

<script>
  export default {
    mounted() {
      // 设置启动页
      this.$uniSplashScreen.open({
        image: '', // 启动页图片路径
        color: '#ffffff', // 启动页背景颜色
        // 启动页动画 (可选项: 'none', 'fade', 'slide'。默认为 'none')
        animationType: 'none'
      })
    }
  }
</script>

In the above code, the image path and background color of the startup page are set. The animationType property is used to set the startup page animation effect. The default is 'none', which means there is no animation effect.

Through the above method, you can easily set the desktop icon and startup page in uniapp. The optimization of these small details can increase the aesthetics of the application and make the user experience better.
