如何在nativescript angular中隐藏ios的水平滚动指示器

import { Component, OnInit } from "@angular/core";
import { ScrollView } from "@nativescript/core";

@Component({
  selector: "app-my-component",
  template: `
    <ScrollView id="scrollViewId">
      <!-- Your content here -->
    </ScrollView>
  `
})
export class MyComponent implements OnInit {
  constructor() {}

  ngOnInit() {
    const scrollView = <ScrollView>this.page.getViewById("scrollViewId");
    scrollView.ios.showsHorizontalScrollIndicator = false;
  }
}
