PushViewController breaks my program when in if statement
I have already created a navigation controller in another class with a root view controller(the login screen). When I hit the login button I want it to push to the dashboard view controller. Here is my code
- (IBAction)logInHit:(id)sender {
if (passWord == true) {
DashBoardViewController *dash = [[DashBoardViewController alloc] initWithNibName:@"DashBoardViewController" bundle:nil];
[self.navigationController pushViewController:dash animated:YES];
}
else if (passWord == false){
UIAlertView *alert = [[UIAlertView alloc] init];
[alert setTitle:@"Incorrect Password"];
[alert setMessage:@""];
[alert setDelegate:self];
[alert addButtonWithTitle:@"Try Again"];
[alert show];
}
}
It works when it pops a view controller and it also works when it is not in the if statement but for some odd reason it breaks when using the code above. The alert view works fine! It is just the push! Please help!
In the App Delegate.h:
NavigationViewController *navView;
Here is the App Delegate (This creates an instance of the navigationController class that I made which is based off of the generic one):
LogInViewController *logInView = [[LogInViewController alloc] init];
navView = [[NavigationViewController alloc] initWithRootViewController:logInView];
[self.window addSubview:navView.view];
Here is the Log:

Ok I got it!
In the NIB file of "LogInViewController", you created an Action called "textEnded", and after that you removed that method, but not the reference from the NIB.
To fix this, go to the LogInViewController NIB to see the Interface Builder, click on your UITextFields, and look inside the Connections Inspector for the method "textEnded" on the Sent Events category. After that, click on the "X" icon to remove the reference.
