* Don't use `@synthesize` unless the compiler requires it.
* Instance variables should be prefixed with an underscore (just like when implicitly synthesized).

## Control Structures
## Expressions

* Use object literals, boxed expressions, and subscripting over the older, grosser alternatives.
* Comparisons should be explicit for everything except `BOOL`s.
* Prefer positive comparisons to negative.
* There shouldn't be a space between a cast and the variable being cast.

``` objc
NewType a = (OldType)b;
```

## Control Structures

* Always surround `if` bodies with curly braces if there is an `else`. Single-line `if` bodies without an `else` should be on the same line as the `if`.
* All curly braces should begin on the same line as their associated statement. They should end on a new line.
* Put a single space after keywords and before their parentheses.
