首次打开的应用程序所有时间都转到教程屏幕

Question

I want to show a screen tutorial only first time you open the app. But the problem is when i navigate to my app first time and go back to rootviewcontroller all time shows tutorial screen. And i want to show "Menu" screen.

How could i set like RootViewController my MenuViewController after tutorial screen?

Thank you!

I have this code in appdelegate.m :

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if ([[[NSUserDefaults standardUserDefaults] valueForKey:@"ISFIRSTTIME"] isEqualToString:@"NO"]) {
    controller = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
}
else {
    controller = [[TutorialViewController alloc] initWithNibName:@"TutorialViewController" bundle:nil];
}
_navController = [[UINavigationController alloc] initWithRootViewController:controller];
[self.window setRootViewController:_navController];

[self.window makeKeyAndVisible];

Answer 1

set in else condition,

[[NSUserDefaults standardUserDefaults]setValue:@"NO" forKey:@"ISFIRSTTIME"];
[[NSUserDefaults standardUserDefaults] synchronize];

Here I am doing like this in my one project,

NSString *identifier;
BOOL isSaved = [[NSUserDefaults standardUserDefaults] boolForKey:@"loginSaved"];
if (isSaved)
{
    identifier=@"home1";

}
else
{
    identifier=@"dis1";
}
UIStoryboard *    storyboardobj=[UIStoryboard storyboardWithName:@"Main" bundle:nil];
UIViewController *screen = [storyboardobj instantiateViewControllerWithIdentifier:identifier];


[self.window setRootViewController:screen];

hope this will help :)

Do something like,

self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
if ([[[NSUserDefaults standardUserDefaults] valueForKey:@"ISFIRSTTIME"] isEqualToString:@"NO"]) {
    controller = [[MenuViewController alloc] initWithNibName:@"MenuViewController" bundle:nil];
}
else {
    controller = [[TutorialViewController alloc] initWithNibName:@"TutorialViewController" bundle:nil];
}
_navController = [[UINavigationController alloc] initWithRootViewController:controller];
[self.window setRootViewController:_navController];

[self.window makeKeyAndVisible];

//Setting "ISFIRSTTIME" to "NO" : it will be "NO" after first time you open the app

[[NSUserDefaults standardUserDefaults]setValue:@"NO" forKey:@"ISFIRSTTIME"];
[[NSUserDefaults standardUserDefaults] synchronize];

1. Set the NO to your Nsuserdefault object in else condition

2. Compare it with the object not the method. Like take bool isfirsttime = your NSuserdefault method. Use if (isfirsttime)

   {} Else {}
