I am in my first days of IOS app development, I am trying to build an authentication system for an already existent iOS App using Objective C.
The app's rootviewcontroller is a tabsview followed by navigationControllers.
What i've done so far:
1- creating the loginviewController class & designing it's UI in the storyboard
2- the same thing for the "registration" & "recover my password" classes
3- linking the root viewcontroller with the login page with a segue of type modal.
4- linking the login page with the registration & recover my password pages with segues of type push.
Now i don't know the steps that i should follow to make the login page appear to the user when he first enters the app & eventually store his state so he can access the app later without having to enter his credentials every time (unless he logs out).
Any help is greatly appreciated, thank you
I am available for any clarifications or eventually some screenshots/source code if needed.
Edit 1 : this is the content of my didFinishLaunchingWithOptions method in my appdelegate.m :
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
TabsViewController *controller = (TabsViewController *)self.window.rootViewController;
controller.managedObjectContext = self.managedObjectContext;
_observer = [[MyStoreObserver alloc] init];
[[SKPaymentQueue defaultQueue] addTransactionObserver:_observer];
//Create sub directories in doesn'n exist
NSString *documentsDirectory =[NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString *pathToFile = [documentsDirectory stringByAppendingString:@"export"];
BOOL isDir = YES;
BOOL isFile = [[NSFileManager defaultManager] fileExistsAtPath:pathToFile isDirectory:&isDir];
if(isFile)
{
//it is a file, process it here how ever you like, check isDir to see if its a directory
}
else
{
[self createSubDirectories];
//not a file, this is an error, handle it!
}
return YES;
}
What should I add/change ??
