Cut to the chase I have recreated my problem as it is fairly self explanatory.
this complies without error:
switch (n) {
case 1:
NSLog(@"");
NSString *aStr;
break;
default:
break;
}
this compiles with error and it's only missing the NSLog():
switch (n) {
case 1:
NSString *aStr;
break;
default:
break;
}
it throws an error at compile "Expected expression before 'NSString'"
Am I missing something here?
In normal C you'd have to enclose this in brackets in both cases. I suspect this may fix your problem:
case 1:
{
NSLog(@"");
NSString *aStr;
break;
}
See this SO question for more info.
Another way to get around this problem is to put a statement between the case label and the first declaration as you've done in your working example above. See the comments and Quinn Taylor's answer for more info.
