“Expected Expression” when declaring and initializing NSInteger in a switch statement
I ran across a strange problem today. Tried something like this:
switch(controlVariable) {
case 0:
NSInteger x = kSomeConstant;
// some other code…
break;
case 1:
// …
default:
// …
}
And to my surprise, XCode complained saying that “Parse error: Expected Expression”. Upon googling, this is what I found.
So, the solution is to put some statement before you initialize NSInteger. If there is no statement that logically fit, you can simply insert a semi-colon “;” before declaring and initializing the integer.
switch(controlVariable) {
case 0:
;
NSInteger x = kSomeConstant;
// some other code…
break;
case 1:
// …
default:
// …
}
