<h4 class="subsection">8.9.2 C99-Like Fast Enumeration Syntax</h4>
|
||
|
|
|
||
|
|
<p>A c99-like declaration syntax is also allowed:
|
||
|
|
|
||
|
|
<pre class="smallexample"> id array = ...;
|
||
|
|
|
||
|
|
for (id object in array)
|
||
|
|
{
|
||
|
|
/* Do something with 'object' */
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
<p>this is completely equivalent to:
|
||
|
|
|
||
|
|
<pre class="smallexample"> id array = ...;
|
||
|
|
|
||
|
|
{
|
||
|
|
id object;
|
||
|
|
for (object in array)
|
||
|
|
{
|
||
|
|
/* Do something with 'object' */
|
||
|
|
}
|
||
|
|
}
|
||
|
|
</pre>
|
||
|
|
<p>but can save some typing.
|
||
|
|
|
||
|
|
<p>Note that the option <samp><span class="option">-std=c99</span></samp> is not required to allow this
|
||
|
|
syntax in Objective-C.
