Cocos2d and UIScrollView

I am developing an IPhone cocos2d app with a scene like the the one depicted in the following image (I hope you can see that):

On the right there is a vertically scrollable menu contained in a separated layer (menulayer) which is itself contained in the main scene's layer. On the left there is a back button contained in the main scene's layer. I am trying to exploit the UIScrollView as described in this link. However,开发者_C百科 despite I can see the UIScrollView working I am experimenting some problems:

1) while the menulayer actually scrolls it seems the menu does not. In fact when a press the menu item 8 the menu item 4 is selected, when I press the menu item 7 the menu item 3 is selected and so on.

2) the back button only works when the menulayer is at its first position

Do you have any idea of how shall I do to fix it?

You need to check you selectors. calls selectors from proper controls. check it carefully.Your problem shows your menu item 8 th selector bind with 4th same for others. some mis binding of selectors is present in your code so check them properly.
