Question

Hello I’m trying to use Three20 with my Monotouch Application with no luck.
I have added the Three20 dll file that I made and all the *.a files that created, to my project.
I have added the argument in my project option and everything was compiled witch means I did that part in the right way.

-gcc_flags "-framework QuartzCore -L${ProjectDir}} -|libThree20CoreSDK -|libThree20NetworkSDK -|libThree20SDK -|libThree20StyleSDK -|libThree20UICommonSDK -|libThree20UINavigatorSDK -|libThree20UISDK -ObjC"

I created a view for testing :

public partial class ViewForTesting : DialogViewController
{

    public ViewForTesting () : base (UITableViewStyle.Grouped, null)
    {
        Section section = new Section();
        TTTabBar strip = new TTTabBar(new RectangleF(0,0,200,40));

        NSMutableArray arr = new NSMutableArray();
        NSString a = new NSString("abc");
        arr.Add(a);
        arr.Add(a);
        strip.TabItems = arr;       

        section.HeaderView = srtip;

        root.Add(section);
        this.Root = root;
    }
}

and this is the error that i get

  at (wrapper runtime-invoke) <Module>.runtime_invoke_void_object (object,intptr,intptr,intptr) <0xffffffff>

=================================================================
Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries 
used by your application.
=================================================================

Also I have updated the monoTouch to 5.2.4

any idea?

Answer 1

You are setting the tabItems property of a TTTabBar to an array of NSStrings, were it should be an array of TTTabItem objects.
