iPhone – Add Tabbar to iOS

loginController = [[LoginController alloc] init];
[window addSubview:tabcontroller.view];
[window addSubview:loginController.view];
[window makeKeyAndVisible];
return YES;

loginController = [[LoginController alloc] initWithNibName:@"login" bundle:nil];
[window addSubview:loginController.view];
[window makeKeyAndVisible];

[window addSubview:tabcontroller.view];

I have an application that contains a tab bar view, and I have a login xib in the same application (login.xib ) And its corresponding class file (LoginController). I hope that when my application starts, the login file should be loaded first, and then once I click the login button, my TabBar view should start.

Tried many methods, but no effect.

The latest one is that I tried to put the following code in the AppDelegate file at the end of the application didFinishLaunchingWithOptions but faced an error:

< /p>

loginController = [[LoginController alloc] init];
[window addSubview:tabcontroller.view];
[window addSubview:loginController.view];
[window makeKeyAndVisible] ;
return YES;

The error is that “loginController” is not declared.

What I missed. If there are other ways to meet my requirements, please let me know.< /p>

In addition, on the clickButton() in login, I am using the event Touch Up Inside.

loginController = [[ LoginController alloc] initWithNibName:@"login" bundle:nil];
[window addSubview:loginController.view];
[window makeKeyAndVisible];

After completing the login check, add the following line .

[window addSubview:tabcontroller.view];

Also, please check where loginCont is used?

Thank you,
