Question

Is there any way to [edit] have a fresh [/edit] redeploy your app from xcode onto the iOS simulator when you hit run, without have to delete [edit] the existing data from the app [/edit] every time?

Answer 1

You shouldn’t have to delete it every time… you should just be able to hit run and it will overwrite or otherwise update the version that is loaded there.

I normally have a debug button to remove all data and add in fake data if necessary and wrap them in a DEBUG flag. This allows me to control it without having to restart the app.

- (void)viewDidLoad
{
    #if DEBUG
        // Make Button and hook it to clearAllData
    #endif
}

- (void)clearAllData
{
    // Clear the Core Data databases
    SDAppDelegate *myDelegate = [[UIApplication sharedApplication] delegate];
    [myDelegate clearAllData];

    // Clear the UserDefaults
    [[NSUserDefaults standardUserDefaults] removePersistentDomainForName:[[NSBundle mainBundle] bundleIdentifier]];

    // Run the initial Setup again
    [self setup];
}
