Question

Objective-C question : Cannot initialize UIViewController in switch case?

switch(anIntegerIndex) {
  case 1:
    UIViewController *vc = [[UIViewController alloc] init];
    break;
  default:
    break;
}

the above has compile error in the UIViewController line. I’m using iOS 5 SDK + xCode 4.2

It’s a common C restriction for switch statements —

You cannot declare local variables inside an individual case unless you put them inside {} brackets.

Simplest thing to do is to put the UIViewController *vc; declaration ahead of the switch and just put vc = [[whatever.. inside the case.
