升级到“@nativescript/core”后找不到 xxport“topmost”

如何解决升级到“@nativescript/core”后找不到 xxport“topmost”

在我的 Nativescript Vue 应用程序中，从 tns-core-modules 更改为 @nativescript/core，现在我遇到了一些问题。我创建了一个类似于 this video 的模态服务。在那里我使用了导入：

import * as frameModule from 'tns-core-modules/ui/frame';

我现在改为：

import * as frameModule from "@nativescript/core";

第一个问题是如果那是正确的。刚刚找到this。

为了将 Modal 放在前面，我使用：

frameModule.topmost()

现在导致警告：

export 'topmost' (imported as 'frameModule') was not found in '@nativescript/core'

哪一堆可能的出口。但它们听起来都不是我需要的。

感谢任何帮助或猜测。

解决方法

Nativescript 8 的导入略有不同

import { Frame } from '@nativescript/core';

// and you can use it like this:
Frame.topmost()
