Case in protected switch [duplicate]

You should wrap each switch statement with {} braces. For example:

switch (someInt) {
    case 0:
    {
        NSLog(@"Case 0");
    }
    break;
    case 1:
    {
        NSLog(@"Case 1");
    }
    break;
}

This has been answered already here by the way – When converting a project to use ARC what does “switch case is in protected scope” mean?
