| <h4 class="subsection">8.9.2 c99-like fast enumeration syntax</h4> |
| |
| <p>A c99-like declaration syntax is also allowed: |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample"> id array = …; |
| |
| for (id object in array) |
| { |
| /* Do something with 'object' */ |
| } |
| </pre></div> |
| |
| <p>this is completely equivalent to: |
| </p> |
| <div class="smallexample"> |
| <pre class="smallexample"> id array = …; |
| |
| { |
| id object; |
| for (object in array) |
| { |
| /* Do something with 'object' */ |
| } |
| } |
| </pre></div> |
| |
| <p>but can save some typing. |
| </p> |
| <p>Note that the option <samp>-std=c99</samp> is not required to allow this |
| syntax in Objective-C. |
| </p> |
