It doesn't work how? Does it compile? If not, what errors or warnings are you getting? If it does compile, are you getting any run-time errors? If it's crashing, have you looked at the crash log?
Debugging descriptions is hard. When you talk about the code doing things, please provide that code, as much of the code as possible. All the code you've provided so far is just very small snippets and wouldn't even compile (for example, it's missing the needed @synthesize directives). If you don't want to reveal what your actual app is doing, then put together a small test app to demonstrate the concept that you are trying to implement. And then post that code here. Also, it would probably help to apply some basic debugging skills to verify that what you think is going on is actually going on. Hope that helps.

Before I take the time to download and look at your project, what debugging have you done already and what have you discovered?This is my "app" is a simple database
in listView there is a var "TAG" that I want to pass in appDelegete as "variabileID"
Except your code shows an instance method (-) and not a class method (+).
I arrange with what I find and what I understand of english document. I think i understand what you say, I have to create a method like this-(int) varID{
PassTag = 1;
return PassTag;
}-(int) cambia {
ListView *my_ID = [[ListView alloc] init];
variabileID = [my_ID varID];
return variabileID;
}-(int) varID{
PassTag = 1;
NSLog(@"PassTag = %d",PassTag);
return PassTag;
