<p><p>如果 <code>object</code> 有时是 NSDictionary 有时是 NSString 你可以检查它并以不同的方式处理它:</p>
<pre><code>+(CGFloat)heightForViewWithObject:(id)object inColumnWidth:(CGFloat)columnWidth {
NSString *titleText = ] ? : object;
}
</code></pre>
<blockquote>
<p>(BOOL)isKindOfClass:(Class)aClass</p>
<p>Returns a Boolean value that indicates whether the receiver is an instance of given
class or an instance of any class that inherits from that class.</p>
