Heute erkläre ich den Verzögerungseffekt für das Startbild bei der Uniapp-Entwicklung, da das Startbild sonst zu schnell ist und blitzschnell vergeht;
1: Ändern Sie die Konfigurationsdatei: manifest.json
"app-plus" : {
"splashscreen" : {
"alwaysShowBeforeRender" : false,
"autoclose" : false,
"delay" : 3000, // 设置延时时间为3000毫秒
"waiting" : true
},
}
2: Führen Sie einige Verarbeitungen auf der App.vue-Schnittstelle durch
onLaunch() {
setTimeout(() => {
plus.navigator.closeSplashscreen();
}, 3000);
},
Drittens: Schließen Sie dies
OK, das war's, führen Sie es aus und sehen Sie sich den Effekt an, es ist perfekt!
1. Laden Sie die offizielle Vorlage und Storybord-Datei herunter und entpacken Sie sie dann!
2. Öffnen Sie die LaunchScreen-Datei mit Hbulider und nehmen Sie die entsprechenden Änderungen vor. Weitere Informationen finden Sie in der Beschreibungsdatei (redme.md).
LaunchScreen lautet wie folgt:

3. Platzieren Sie die Startbilder xxx@2x und xxx@3x direkt unter dem Projekt, nicht unter der Bilddatei:
4. Cloud-Verpackungstest, der Effekt ist erst nach dem Verpacken sichtbar;
Er widmet sich seit mehr als 30 Jahren der Technologieforschung und beherrscht verschiedene Sprachen wie Java, Linux, Javascript, PHP, CSS usw. Er hat viele Beiträge im Open-Source-Bereich geleistet Entwicklerdokumentationsstation, um einige Themen in der Technologieentwicklung als zukünftige Referenz zu teilen
