Nativescript Angular如何切换组件(选项卡模板)

import { Component } from "@angular/core";
import { TabView, TabViewItem } from "tns-core-modules/ui/tab-view";

public tabs: Array<any> = [
    { title: "Tab 1", content: "This is the content of Tab 1" },
    { title: "Tab 2", content: "This is the content of Tab 2" },
    { title: "Tab 3", content: "This is the content of Tab 3" }
];

<TabView>
    <ng-template ngFor let-tab [ngForOf]="tabs">
        <TabViewItem [title]="tab.title">
            <StackLayout>
                <Label [text]="tab.content"></Label>
            </StackLayout>
        </TabViewItem>
    </ng-template>
</TabView>
