Answer 1

You could use the open or focus event to pick up when someone hits the screen and then either:
If this is a connected app, and you're downloading the user profile on login, you could store a flag to say tutorialSeen or similar. Check this when the window opens / focuses or
if not connected or you want to store locally, store the flag in the Ti.App.Properties under a user profile.
(you could equally store a count value that increments when they hit the screen but since you just want the first time captured, I'd go with a) capture event, b) check property, c) if false, set to true and show tutorial, d) if true, skip.)
Hope that helps!

I think you do not need to store the user visit count if your only purpose is to show the Instruction window only when user login into the app for first time.
You can do it this way:
someController.js
function onLoginSuccess() {
// getInt() will return the value of INSTRUCTION_WINDOW property, you can name this property whatever you want.
// if this property does not exist, then it will return the value of the second parameter.
var showInstruction = Ti.App.Properties.getInt("INSTRUCTION_WINDOW", 1);
if (showInstruction) {
Alloy.createController('instructionWindow').getView().open();
} else {
Alloy.createController('nextWindow').getView().open();
}
}
// logout function can be anywhere
// remember to set the property to 1 if you want to show the instructions again after logout and then login.
function logout() {
Ti.App.Properties.setInt("INSTRUCTION_WINDOW", 1);
}
instructionWindow.js
$.instructionWindow.addEventListener('open', function () {
// after opening the instruction window, set this property to 0
// so it won't be shown up the next time the already logged-in user opens the app
Ti.App.Properties.setInt("INSTRUCTION_WINDOW", 0);
});

first you set the nsuserdefaults value #"1".
[[NSUserDefaults standardUserDefaults] setObject:#"1" forKey:#"showtheinstruction"];
[[NSUserDefaults standardUserDefaults] synchronize];
after this you have to compare this string and shows the instruction message.
NSString *str_savedValue = [[NSUserDefaults standardUserDefaults]
stringForKey:#"showtheinstruction"];
if (str_savedValue isEqualToString:#"1") {
// show the instruction window.
}
else
{
// don't show the instruction window.
}
