Question

is there in objective-c something similar to ruby’s:

foobar = foo || bar

while foo is nil and bar is 1… so foobar will become 1 or something else if foo wouldn’t be nil 🙂

Answer 1

Use C’s ternary conditional operator:

foobar = foo != nil ? foo : bar;

In general, it takes the form

<var> = <condition to test> ? <true value> : <false value>;

As Wevah noted, if you enable GNU C99 extensions (-std=gnu99) you can also do

foobar = foo ?: bar
