Short way to write conditional assignment in ObjC

Question

Does Objective-C have an even shorter way of writing this line of code? ``` a = b ? b : c; ``` That is, a way to say, `a` is equal to `b` as long it is not `nil`, else `c`. This is like Ruby's operator `||=`

Accepted Answer

Does the following work for you:

```
a = b ? : c;
```

(This syntax is a GNU extension to C, so you might have to use the GCC and not LLVM - http://gcc.gnu.org/onlinedocs/gcc-3.2.3/gcc/Conditionals.html#Conditionals).
