iOS Question Problem getting height of NavigationBar ?

[henrywood]

I am trying to get the height of the NavigationBar (don't want to hardcode any values).
I've tried:

  Dim NativeMe2 As NativeObject = Main.NavControl
  ' self.navigationController.navigationBar.frame.size.height;
  Dim NativeMe3 As NativeObject = NativeMe2.GetField("navigationBar").GetField("frame").GetField("size").GetField("height")
  Dim h As Object = NativeMe3.AsNumber

I am getting this error:

Application_Start
Application_Active
Error occurred on line: 110 (modshare)

Any ideas what's wrong ?

Why do you need this code? Handle Page_Resized event and you will get the correct values.

 

[henrywood]

Well the code is in a shared, reusable code module so all code related to the functionality of the shared module should be contained within it.
But did you mean to say that you can have multiple Page_Resized Handlers in multiple code modules ?

 

[Erel]

You cannot have multiple handlers. However the correct way to find the page size is by handling Page_Resize event. You can call any sub you like from this event.
