問題描述
最近在學習過程中發現ionic2專案執行在真機上,啟動頁後會有3-5秒的白屏時間,使用者體驗不是太好。
解決過程
一、安裝Cordova splash screen外掛
- $ cd myapp
- $ ionic plugin add org.apache.cordova.splashscreen
二、配置config.xml檔案
<?xml version='1.0' encoding='utf-8'?>
<widget id="com.lishan.sidemenu" version="0.0.1" xmlns="http://www.w3.org/ns/widgets" xmlns:cdv="http://cordova.apache.org/ns/1.0">
<name>Sidemenu</name>

三、配置app.component.ts initializeApp() {
this.platform.ready().then(() => {
// Okay, so the platform is ready and our plugins are available.
// Here you can do any higher level native things you might need.
StatusBar.styleDefault();
Splashscreen.hide();//新增程式碼
});
}
