New issue 182 by daniel....@gmail.com: Switch case in protected scope
http://code.google.com/p/j2objc/issues/detail?id=182

The translation of this method in Java:

private static int testMethod(int value) {

switch (value) {
case 1:
String test = "test";
return 2;
default:
return 4;
}
}
}

Produces this output:
+ (int)testMethodWithInt:(int)value {
switch (value) {
NSString *test;
case 1:
test = @"test";
return 2;
default:
return 4;
}
}

XCode complains (error) for both cases "1" and "default" - "Switch case is
in protected scope".
This happens when you define a String inside a case, it's not a problem
with an int (I am not experienced enough in Objective-C to answer why is
this a problem at all).

The fix is to move the declaration of test variable above the switch
statement.

Oops, I didn't notice that it already exists. But maybe this code example
is a bit more simple and easier to track down the problem.

The temporary variable is now moved outside of the switch statement, inside
a block to avoid clashing with other variables with that name:

{
NSString *test;
switch (value) {

case 1:
test = @"test";
return 2;
default:
return 4;
}
}
