推荐答案

我认为您现在无法更改 iOS 中 NavigationBar 的默认高度.您可以查看此答案以获取更多信息:

I don't think you can change the default height of NavigationBar in iOS right now. You can check this answer for more information:

它可能适用于具有此线程中解决方案的早期 iOS 版本:

And it may work with earlier iOS version with solutions in this thread:

我建议您隐藏该页面中的默认 NavigationBar 并在那里添加自定义 NavigationBar，然后您可以为自定义 NavigationBar 设置任何您想要的高度.

I would recommend you to hide the default NavigationBar in that page and add a custom NavigationBar there, then you can set any height you want to the custom NavigationBar.

在页面中，隐藏默认的NavigationBar:

In the Page, hide the default NavigationBar:

public AboutPage()
{
    InitializeComponent();

    NavigationPage.SetHasNavigationBar(this,false);
}

然后添加您的自定义导航栏:

And then add your custom NavigationBar:

<StackLayout>

    <StackLayout HeightRequest="150" BackgroundColor="Yellow" Orientation="Horizontal">

        <Button Text="Menu" HorizontalOptions="Start" Padding="5"/>
        <Label Text="I'm custom navigationBar" VerticalOptions="CenterAndExpand" HorizontalOptions="CenterAndExpand"/>

    </StackLayout>

    <Grid>
       <!--... my layout-->
    </Grid>

</StackLayout>

如果您想更改项目中所有导航栏的高度，您可以在那里拥有一个带有自定义 NavigationPage 的 basePage.

If you want to change the height of all the navigationBar in your project, you can have a basePage with custom NavigationPage there.

我在这里上传了一个示例项目，并在 AboutPage 中添加了自定义导航栏.您可以查看它并随时问我任何问题.

I uploaded a sample project here and added the custom navigationBar in AboutPage. You can check it and feel free to ask me any question.
