Question

BUT! add a random statement before:

Any thoughts?

Answer 1

This isn’t a switch-statement bug, it’s a limitation in the C language. In C, the first statement after a case label cannot be a variable declaration. You can get around this by either declaring the variables before the switch statement or creating the variable inside a block of code (see below). Obviously, you can also re-order your code (if possible) so that another statement comes before the variable declaration.

Example 1:

CGRect newRect = CGRectZero;
switch( var ) {
  case 0:
    // do some stuff
    break;
  case 1:
  default:
    newRect = [someVar someMethodThatReturnsARect];
    // other code
    break;
}

Example 2:

switch( var ) {
  case 0:
    // do some stuff
    break;
  case 1:
  default: {
    CGRect newRect = [someVar someMethodThatReturnsARect];
    // other code
    break;
  }
}

Example 3:

switch( var ) {
  case 0:
    // do some stuff
    break;
  case 1:
  default:
    // some code re-ordered to here
    CGRect newRect = [someVar someMethodThatReturnsARect];
    // rest of the other code
    break;
}
