How to set different AppDelegate for different tar

Question

I'm very very new to the target concept in Xcode. I have followed this tutorial to learn to create two targets in the same project. I just want to know how to make target A use AppDelegateA.swift as its designated app delegate, and target B use AppDelegateB.swift as its designated app delegate. Because on the tutorial, it actually teaches how to make two apps from the same AppDelegate. But I make two (almost) completely different apps, that share a lot of resources and libraries.

And while we're on the subject, can I also have target A use a storyboard called Main, and target B also use a storyboard called Main, but they are actually a different storyboard (but put together inside the same project)?

Answer 1

Yes you can create 2 different based upon the target make following changes:

in the projects

main.m

you could do something like

int main(int argc, char *argv[])
{
    @autoreleasepool {

        NSString *appDelegateName;
        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone){
            appDelegateName =  NSStringFromClass([AppDelegateIPhone class]);
        } else {
            appDelegateName =  NSStringFromClass([AppDelegateIPad class]);
        }
        return UIApplicationMain(argc, argv, nil, appDelegateName);
    }
}

But IMO you should not do it.

Instead doi it as apple does it to, in app delegate load different view controllers or different XIBs.

    @implementation AppDelegate

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
    {
        self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
        // Override point for customization after application launch.
        if ([[UIDevice currentDevice] userInterfaceIdiom] == UIUserInterfaceIdiomPhone) {
            self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPhone" bundle:nil] autorelease];
        } else {
            self.viewController = [[[ViewController alloc] initWithNibName:@"ViewController_iPad" bundle:nil] autorelease];
        }
        self.window.rootViewController = self.viewController;
        [self.window makeKeyAndVisible];
        return YES;
    }

@end

Hope my answer here helps for second part of including multiple AppDelegate files based on targets. https://stackoverflow.com/a/43227300/2715840

For first part of using multiple targets you can do so by simply doublicating the base target , you will get your plist already copied , change name based on new target or keep it same name plist.info but in different path. for separating code files(like Appdelegates) , storyboards and Assets , or firebase plist config files you can find my answer in the above like valid for these purposes.

Hope this helps.
