In xCode, I get the error "The tip was loaded, but the exit point has not been set"?

Question

I know that there are several questions asking the same thing, but none of their solutions worked for me.

I made my own class viewController (Home), and I made .xib separately. (In fact, I will have 2 tips - one for loading the ipad and one for the iphone).

When I try to instantiate a home class, I got the error that I mentioned in the question.

In the xib file, all I did was drag the viewcontroller object from the library onto the screen, and it automatically added a viewcontroller icon below the file owner and the first responder. Then I went into the inspector of the viewController object and changed the class from viewController to Home.

The next step that I determined from the solutions is to connect the output for viewing from the inspector. I'm not quite sure what I should connect to. The solutions I found say to connect it to the view icon, but again, all I see is the owner of the file, the first responder and the vc object. He does not connect with any of them.

Here is what I added to the application delegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { Home *homePage = [[Home alloc] initWithNibName:@"HomeIpad" bundle:nil]; UINavigationController *navController = [[UINavigationController alloc] initWithRootViewController:homePage]; [self.window addSubview:navController.view]; [self.window makeKeyAndVisible]; return YES; } 

Answer 1

the problem was that for the file owner I did not set the class Home

Answer 2

I suggest you create a Nib using Xcode File-> New-> New File → Cocoa Touch-> UIViewController subclass-> with XIB for the user interface (do it twice, once when Targeted for iPad is checked), I believe that this The most reliable way to create and connect XIB.

Even if you want to use two XIBs for the same controller, create a second VC subclass using any temporary name (e.g. tempvc). Now rename tempvc.xib to HomeIpad.xib. Right-click on HomeIpad.xib and select Open As-> Source Code. In the source, find tempvc and replace it with the name of your controller for all occurrences. Everything should be fine now.

You do not need to drag the view controller. Just drag and drop the UIView and attach the file owner view to this UIView.
