I was just asked yesterday if there is any shorthand in Objective-C for "if this thing = nil, then instantiate a new instance from the class"
Something like this:
NSString x;
if ([x isEqualtoString:nil]) {
x = @"yo";
}
Feel free to replace NSString with any class.
And we messed around a bit looking for any shorthand and though it looked like a terrible idea since the comparison is done against integers using the ternary operator, I'd like to know exactly why it's a terrible idea.
NSString x;
x = (x) ?: @"yo";
Thanks in advance.
