在Ios中的主详细信息页

Question

我在Ios中有主详细信息页面，现在我需要在详细信息页面中显示一些值，当点击母版页中的按钮时。可以帮助我实现它。

public class StoresTabletPage : MasterDetailPage 
{ 
    public StoresTabletPage() 
    { 
     Title = "Stores";   
     Detail = new ContentPage 
     { 
      IsVisible = true, 
      MinimumWidthRequest = 100, 

      Content = new StackLayout 
      { 
       VerticalOptions = LayoutOptions.Center, 
       HorizontalOptions = LayoutOptions.Center, 
       Children = 
       { 
        new Label { Text = "Label1", FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label)) } 
       } 
      } 
     }; 
     Master = new ContentPage 
     { 
      MinimumWidthRequest = 500, 
      Title = "string", 
      Content = new StackLayout 
      { 
       VerticalOptions = LayoutOptions.Center, 
       HorizontalOptions = LayoutOptions.Center, 
       Children = 
       { 
        new Button{ Text = "1", FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Button)) } 
       } 
      } 
     }; 

所以，按钮被点击的母版页时，应详细页面显示LABEL1。
