我在 exrin 中使用 MasterDetailPage 这是我的 ViewContainer 公共类 MainViewContainer ： Exrin.Framework.ViewContainer, IMasterDetailContainer { private readonly MasterDetailPage r_MasterPage;
public MainViewContainer(MenuStack i_MenuStack, MainStack i_MainStack)
: base(eContainer.Main.ToString())
{
r_MasterPage = new MasterDetailPage();
MasterDetailProxy masterProxy = new MasterDetailProxy(r_MasterPage);
NativeView = masterProxy.View;
Proxy = masterProxy;
DetailStack = i_MainStack;
MasterStack = i_MenuStack;
RegionMapping.Add(eRegions.Menu, ContainerType.Master);
RegionMapping.Add(eRegions.Main, ContainerType.Detail);
}
public IHolder MasterStack { get; set; }
public IHolder DetailStack { get; set; }
public IMasterDetailProxy Proxy { get; set; }
public bool IsPresented
{
get
{
return r_MasterPage.IsPresented;
}
set
{
r_MasterPage.IsPresented = value;
}
}
public void SetStack(ContainerType i_ContainerType, object i_Page)
{
switch (i_ContainerType)
{
case ContainerType.Detail:
r_MasterPage.Detail = i_Page as Page;
break;
case ContainerType.Master:
r_MasterPage.Master = i_Page as Page;
break;
}
}
}
这是我的 IMasterDetailProxy 公共类 MasterDetailProxy ： IMasterDetailProxy { private readonly MasterDetailPage r_MasterPage;
public MasterDetailProxy(MasterDetailPage i_MasterPage)
{
View = i_MasterPage;
r_MasterPage = i_MasterPage;
}
public object DetailNativeView
{
get
{
return r_MasterPage.Detail;
}
set
{
r_MasterPage.Detail = value as Page;
}
}
public object MasterNativeView
{
get
{
return r_MasterPage.Master;
}
set
{
Page page = value as Page;
if(string.IsNullOrEmpty(page.Title))
{
page.Title = "Please set your MasterPage Title";
}
r_MasterPage.Master = page;
}
}
public object View { get; set; }
}
我正在使用它在主页面上显示菜单，在详细信息部分显示页面。我的菜单视图是

我有几个问题：1.在Android上我自动有汉堡菜单按钮但在iOS上我没有任何图标，我尝试为iOS的菜单视图设置一个图标使用
<base:PageProxy.Icon>
<OnPlatform x:TypeArguments="FileImageSource">
<On Platform="iOS" >Icon-Small.png</On>
</OnPlatform>
</base:PageProxy.Icon>
在菜单视图上，但它不起作用。2. 在 iOS 上，页面标题是“请设置您的 MasterPage 标题”（如果页面标题为空，代理会设置它）但是您可以在菜单视图中看到我为页面设置了标题，这仅在 iOS 上发生。 https://drive.google.com/file/d/0B3YFjr58f7_OMC04Y0FreVRvVlE/view?usp=sharing
当按下菜单上的链接时，我希望母版页消失，它当前保持打开并隐藏部分详细信息页面，直到我按下详细信息页面。
在详细信息页面上，我有一个返回按钮，所以如果我想导航到另一个页面，我必须先按返回，然后我可以看到菜单图标以显示主页面并选择另一个链接。如何替换后退按钮以始终显示汉堡菜单按钮？这是我的堆栈
