iOS Question call page to tabbar

Please use [code]code here...[/code] tags when posting code.

You will need to make the page variable in each of the modules public, initialize it when the program starts and set it with tbc.Pages = Array (Module2.Page, Module3.Page)

There is a single module in the project you uploaded.

im so sorry , wrong occur . this is correct project

Use the debugger to go over the program execution one line after another.

I haven't run your code but I'm pretty sure that the problem is here:
psignup.pagesignup.TabBarItem = t1

This page was not initialized.

@Erel mate did you see my code ?
its correct ?
i initialize pagesignup in psignup module with this code :
pagesignup.initialized("pagesignup")
its true ? or not ?
if not how i initialze page ?

I saw your code. Your code is incorrect. See my previous post. The page was not initialized when you try to set the TabBarItem.

You must learn to use the debugger. This is a simple issue that shouldn't take more than a few minutes to solve with the debugger.

i can use debugger , and when i create break point to my code and then run the application , app pause on my break piont
and in when i equal my page to tabBaritem application crash and say object was not initialzed ,
and i dont know what i do , i initialize my page in module whit this code :
page.initalze("page1")

Test whether this code is called before the other code.

i must initialize page before set tabBaritem to my page ? like this : ?
module1.page1.initialize("page1")
module1.page1.tabBarItem = tabBaritme1

Any object with an Initialize method must be initialized before you can do anything with it.

At this point I recommend you to go over your project and debug it until it works.

@Erel mate thanks a lot , i initialize and application not crash but two tab of them instead of show page , show black screan and dont show anything . what's wrong ?

I'm sorry but I cannot debug the program for you. Bumping the question will not help.

You need to work with the debugger and find out what is happening.

dear @Erel i dont say debug for me ,
i use debug tools and when check point arrive to module1.page1.tabBarItem screan become black and dont show any error ,
if you have example for tabBar with module page please give me that i can see that and understand what i do ,

It doesn't matter whether you use a single module or multiple modules. The result is exactly the same. If it is simpler for you to use a single module then use a single module.
