I have a question that is similar to this SO question, but slightly different (or my skills don’t allow me to follow the directions with confidence). I have an existing game app that has one view controller and one nib and works fine. I want to convert it to have a tab bar controller. I want the original, existing view controller to be on the first tab, and I wrote a new view controller and a new nib for the second tab, which will be dedicated to game settings. At this stage, the app builds and runs fine with the new nib and view controllers in the project (but with no further edits — no attempt to add the tab bar controller etc). The modified app should simply have two views each accessible from one of the two tabs.
Sorry for the long bkgnd. I’m following the accepted answer to the above-referenced question. The first 4 steps I have done or can do. The 5th step is to Delete the old version of your Main View Controller from the NIB file and also remove the IBOutlet property from the Application Delegate. I don’t think I have such an IBOutlet in my app (which is different from the OP’s app). Should I delete the object view controller shown in this list? Or am I on the wrong track here?
Additional Info
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
// Set up view controller & load a clean view
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
self.viewController = [[P3ViewController alloc] initWithNibName:@"P3ViewController" bundle:nil];
self.window.rootViewController = self.viewController;
NSLog(@"P3ViewController now active");
[self.window makeKeyAndVisible];
return YES;
