What's the shortest way to negate a BOOL in Objective-C?
I remember in Java you could just go
bool yesNo = YES;
!yesNo;
and it would be NO automatica开发者_高级运维lly. I've tried this a few times in Objective-C but it doesn't seem to work. Is there a language specific way to do this in Objective-C?
It works more or less the same way - you just have to remember to assign the result of the negation expression back to the variable, like so:
yesNo = !yesNo;
