Question

I’m working with my first grasping of a settings screen. I set a boolean or something like that from within the settings screen which then would change something in the main viewcontroller.

For example, “Enable Private Browsing?”
^ Declared within the settings viewcontroller, returns a “YES” or “NO” boolean.

And if it returns yes, it would be enabled within the main viewcontroller. However, I need to know how it’s possible to obtain that boolean in the main viewcontroller to actually enable/disable it using the value set in the settings viewcontroller.

Thanks for your time, and I greatly appreciate it.

Answer 1

you can use NSUserDefaults

save on settings viewcontroller with:

[[NSUserDefaults standardUserDefaults] setObject:@"somecustomsetting" forKey:@"enablePrivateBrowsing"];

retrieve on mainviewcontroller with:

[[NSUserDefaults standardUserDefaults] objectForKey:@"enablePrivateBrowsing"];

this will be persistant(will be saved even after the app is closed) so remember to do
on your settings view controller

if( [[NSUserDefaults standardUserDefaults] objectForKey:@"enablePrivateBrowsing"]){
privatebrowsingswitch.on = NO;
}else{
    if([[[NSUserDefaults standardUserDefaults] objectForKey:@"enablePrivateBrowsing"] isEqualToString:@"somecustomsetting"]){
    privatebrowsingswitch.on = YES;
        }else{
       privatebrowsingswitch.on = NO;
             }

}
