This library allows you to show and play Leadbolt ads.
You need to first register with Leadbolt: www.leadbolt.com

To show an ad:
1. Add this line to disable https limitations:
2. Initialize LeadBolt object with your key.
3. Call LoadModuleToCache to load an ad (module should be inapp or video).
4. Call ShowModule to show a previously loaded ad.

Monitor the logs for relevant messages.

Sub Process_Globals
   Public App As Application
   Public NavControl As NavigationController
   Private Page1 As Page

   Private lb As Leadbolt
End Sub

Private Sub Application_Start (Nav As NavigationController)
   NavControl = Nav
   lb.Initialize("lb", "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxbXNCRKiQGgP")
End Sub

Private Sub Page1_Click
   lb.ShowModule("inapp", Page1)
End Sub

Private Sub lb_Loaded

End Sub

Private Sub lb_Failed

Library installation

The zip file contains three files with the following extensions: .xml, .a and .h.
You need to copy the xml file to the internal libraries folder on the Windows computer.
If you are using a local Mac builder then you need to
- Copy the .a and .h files to the Mac Libs folder.
- Download Leadbolt SDK and copy libAppTracker.a to the Mac Libs folder.

I need a problem with event in my library:

In a event of my library started by

in ObjectiveC (library)
[B4IObjectWrapper raiseEventFromDifferentThread:self :@"_onselected:" :@[pRet];
in B4i
Sub omyobj_onSelected(ItemName As String)

   hd.ProgressDialogShow("Downloading Messages...")


Problem: The HUD and TOAST not appear, but if is out of this event the HUD appear normally.

Obs: The event _onSelected works perfectly

i have write them, but they haven't a b4i library (only b4a).

can you post here the libAppTracker.a compatible with iLeadbolt library b4i (Ver.1.32 with last b4i Ver. 2.51)
I have a mac builder, i suppose the remote builder work fine.

Or update iLeadbolt library b4i to last sdk, 7.0 support also the native.
