Question

I have the current code:

if ([fetchedObjects count] == 0){
    Timetable *info = nil;
} else {
    Timetable *info = [fetchedObjects objectAtIndex:0];
}
// Return Data
return info;

Inside a method in one of my classes. This code should run but xcode gives me the errors:

Use of undeclared identifier 'info'

for the return info and

Unused variable 'info'

for the Timetable *info parts.

I have no clue why this is happening and the app does crash if I try to run it due to this. If i were to set the timtable without the if statement like this, it would work:

Timetable *info = [fetchedObjects objectAtIndex:0];

Can someone tell me what i’m doing wrong? Thanks.

Answer 1

You are declaring info variables in two different places, inside the if or else. info is not visible outside of the block. (This is basic C language stuff.)

This reads a little better:

Timetable* info = nil;
if ([fetchedObjects count] > 0)
{
   info = [fetchedObjects objectAtIndex:0];
}
return info;
