#鸿蒙通关秘籍#关于App首页加载时长，如何通过自定义组件优化？

自定义组件的生命周期管理至关重要。在aboutToAppear回调中，避免阻塞性操作，建议将长耗时任务放在异步流程中执行，参考如下：

@Entry @Component struct Index { @State private text: string = ""; private count: number = 0;

aboutToAppear() {
    this.computeTaskAsync();
    let context = getContext(this) as Context;
    this.text = context.resourceManager.getStringSync($r('app.string.startup_text'));
}

computeTask(): void {
    this.count = 0;
    while (this.count < 10000000) {
        this.count++;
    }
}

private computeTaskAsync(): void {
    setTimeout(() => { 
        this.computeTask();
    }, 1000);
}

}
