Question

I have a simple block of code that needs to set an NSString as one thing or another. In it’s most basic form, it looks like this:

if (conditionMet){
   NSString *outputString=[NSString stringWithString:@"A"];
} else {
   NSString *outputString=[NSString stringWithString:@"B"];
}
return outputString;

But, I’m getting a “Use of undeclared identifier ‘outputString'” error. What is a better way to do this?

I understand this is a pretty basic question, so any quick pointers on how to do this would be terrific. Thanks for reading.

What about ?

NSString *outputString;
if (conditionMet){
   outputString=@"A";
} else {
   outputString=@"B";
}
return outputString;

You need to learn about scope

Shorter version :

return conditionMet ? @"A" : @"B" ;

It’s called ternary condition
