[myButton addTarget:self selector:@selector(clicked:)....and so on whic sends us to your method:
-(void)clicked:(id)sender {
//your code and such
//now lets say we are setting this to DISABLED (lets call it 'NO', unless you wanna get into some weird typedef stuff, lets not for simplicity)
[[NSUserDefaults standardUserDefaults] setBool:NO forKey:@”myDefualt”]
}
now what we just did there was create a user default that can be referenced from here on out via the key term @”myDefault”. so, in your applicationDidLaunch method, you can add something like:
if([[NSUserDefaults standardUserDefaults] boolForKey:@”myDefault”]==YES) {
//perform code for enabled button
} else {
//perform code for disabled button
}

hope that helps! and the code here isnt 100% because I am on my PC, just check out the documentation for other support NSUserDefaults, I do like the bool one, I use it in my applications constantly to see whether or not the user has run it before

I was wondering though, do you know how to save the state of a UIButton using NSUserDefaults? I have a button that becomes disabled when the user taps it, and I just need to find a way to save the disabled state for the next time the user launches the application. Any help would be great -thanks again Great tutorial, thank you for the info.
